Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of concrete preparation, and in particular to a high-altitude high-cold freeze-thaw resistant concrete and a preparation method thereof. BACKGROUND

[0002] The air is thin, the water vapor and dust content are less, and the atmospheric transparency is high on the plateau. During the day, the solar radiation reaches the ground through a short atmospheric path, and due to the high atmospheric transparency, the weakening effect is also correspondingly small, so that the ground receives more solar radiation, and the temperature is relatively high. At night, due to the weak heat preservation effect of the thin gas on the ground, the temperature drops rapidly, and the temperature often drops below zero, resulting in large daily temperature changes in the plateau environment, with an annual daily temperature difference of about 14℃, and a maximum daily temperature difference of more than 30℃. In some areas, the number of days with alternating positive and negative temperatures can reach 180d, which is much larger than that in plain areas and hilly areas. Due to the frequent alternation of seasons and dry and wet changes, various factors lead to higher average freeze-thaw times of concrete in the plateau environment, especially the freeze-thaw damage to the terrace concrete is serious.

[0003] The climate characteristics of low air pressure and large temperature difference on the plateau result in large loss of air content in concrete, unstable air bubbles, and poor air entraining effect, which leads to poor freeze-thaw resistance of concrete.

[0004] During the hardening of concrete, a large amount of hydration heat is generated by cement hydration, and the internal temperature rises continuously. Due to the large diurnal temperature difference on the plateau, the temperature difference between the surface and the interior of the concrete is large, at this time the surface of the concrete will be subjected to tensile stress, and the early tensile strength of the concrete is very low, thus cracks occur, and the concrete is easily damaged by freeze-thaw in winter.

[0005] The aggregate has a high water absorption rate, and the aggregate shrinks and deforms greatly when frozen, causing large-area cracking and peeling of the concrete.

[0006] In the industry, when preparing freeze-thaw resistant concrete, air-entraining agents, reducing the water-binder ratio, and adding organic fibers are often used to improve the freeze-thaw resistance of concrete, among which the effect of air-entraining agents is the most obvious. The currently published patent CN120208612A discloses a high-altitude freeze-thaw resistant concrete and a preparation method thereof, but this method still has many defects. The surface and internal temperature difference of the concrete needs to be monitored throughout the process, and when the temperature difference exceeds 15℃ within 28 days of the curing period, a 10-20mm foam insulation layer needs to be added, which is more suitable for three-dimensional structures. However, for terrace structures, even if the surface layer is insulated, the bottom layer is still frozen. This method is not suitable for terrace structures and cannot ensure the freeze-thaw resistance of the concrete in the later stage.

[0007] Therefore, the present application is proposed. SUMMARY

[0008] The application aims to provide a highland alpine freeze-thaw resistant concrete and a preparation method thereof.

[0009] The application aims to achieve the above-mentioned purposes through the following technical solutions. The highland alpine freeze-thaw resistant concrete comprises the following components in parts by weight: 6-15 parts of silicate cementing material, 20-35 parts of fine aggregate, 20-35 parts of coarse aggregate, 10-20 parts of ABS aggregate, 5-8 parts of water, 0.5-1 part of plasticizer, 0.01-0.03 part of composite modified air entraining agent, 0.5-1 part of modified composite plant powder, 0.5-1 part of modified loofah sponge, 0.5-1 part of inorganic fiber, 0.05-0.1 part of graphene oxide and 0.5-1 part of animal fat.

[0010] The application also provides a preparation method of the highland alpine freeze-thaw resistant concrete. The fine aggregate, the coarse aggregate and the ABS aggregate are added into a forced mixer and continuously stirred for 1-2 min, then the water, the silicate cementing material, the plasticizer, the composite modified air entraining agent, the animal fat and the graphene oxide are added and continuously stirred for 2-3 min, and finally the modified composite plant powder, the modified loofah sponge and the inorganic fiber are added and continuously stirred for 2-3 min until the concrete mixture is uniform.

[0011] Compared with the prior art, the highland alpine freeze-thaw resistant concrete and the preparation method thereof have the following beneficial effects. The modified plant powder, the modified loofah sponge and the inorganic fiber are added to absorb and retain water in the concrete, prevent plastic shrinkage cracks of the concrete, improve the tensile strength of the concrete, resist the damage caused by large shrinkage due to high temperature difference, improve the freeze-thaw resistance, form a nano water-resistant film in the concrete to prevent water from entering, thus eliminating the conditions for freeze-thaw cycles, the ABS aggregate is added to the concrete to reduce the water absorption rate of the aggregate, reduce the crushing index and obtain good freeze-thaw deformation resistance, the graphene oxide is added to the concrete to reduce the internal water freezing temperature and improve the freeze-thaw resistance, the composite modified air entraining agent is added to the concrete to reduce the air content loss and improve the stability, and the freeze-thaw resistance of the concrete reaches F400 through the simulation of the highland freeze-thaw cycle test, thus reducing the freeze damage of the concrete and prolonging the service life of the concrete member.

[0019] The schemes provided by the present application are described in detail below.

If the reagents or instruments used in the embodiments of the present application are not specified by the manufacturer, they are all conventional products that can be purchased on the market.

[0020] The embodiment of the present application provides a high-altitude alpine freeze-thaw resistant concrete, which comprises the following components in parts by weight: 6-15 parts of Portland cement binder, 20-35 parts of fine aggregate, 20-35 parts of coarse aggregate, 10-20 parts of ABS aggregate, 5-8 parts of water, 0.5-1 part of plasticizer, 0.01-0.03 part of composite modified air entraining agent, 0.5-1 part of modified composite plant powder, 0.5-1 part of modified loofah sponge, 0.5-1 part of inorganic fiber, 0.05-0.1 part of graphene oxide, and 0.5-1 part of animal fat.

[0021] Preferably, in the concrete, the modified composite plant powder is a modified composite plant powder prepared by mixing and crushing wheat straw and cotton stalks in a mass ratio of 6:4, soaking the mixed powder in a 5% NaOH solution at room temperature for 20 hours for pretreatment, and then drying the pretreated powder in equipment.

[0022] Preferably, in the concrete, the modified loofah sponge is prepared by drying a plant loofah, mixing and crushing the dried loofah to obtain fiber filaments with a length of 1-3 mm, soaking the fiber filaments in a 4% NaOH solution for 24 hours for pretreatment, and then drying the pretreated fiber filaments in equipment.

[0023] Preferably, in the concrete, the silicate cementing material is ordinary Portland cement P.O 42.5, which is used as an inorganic cement main material to provide overall structural strength for the concrete.

[0024] The fine aggregate is at least one of machine-made sand, river sand, and recycled sand, and mainly provides a filling framework for the concrete during molding.

[0025] The coarse aggregate is at least one of gravel, pebbles, and recycled stones, and mainly provides a framework for the concrete during molding.

[0026] The plasticizer is a polycarboxylic acid high-performance water reducing agent, which can reduce the water consumption of the concrete, improve the construction performance, and increase the strength of the concrete.

[0027] Preferably, in the concrete, the ABS aggregate is a continuous grading aggregate with a particle size of 4.75 mm or more, an aggregate density of 1.21 g / cm3, and a water absorption rate of zero. The ABS aggregate is prepared by cleaning, crushing, heating to 200°C, cooling, and grinding a waste recycled ABS plastic to obtain a continuous grading aggregate with a particle size of 4.75 mm or more. The ABS aggregate can reduce the crushing index and has good anti-freeze-thaw deformation performance.

[0028] Preferably, in the concrete, the inorganic fiber is a basalt fiber with a nominal length of 9 mm, a single-filament nominal diameter of 15 μm, a tensile strength of 1800 MPa, an elastic modulus of 50 GPa, a breaking elongation of 3%, and an alkali-resistant strength retention value of 80%.

[0029] Preferably, in the above-mentioned concrete, the composite modified air-entraining agent is a composite modified air-entraining agent composed of sodium dodecylbenzenesulfonate and triterpenoid saponins in a mass ratio of 3:7; this composite modified air-entraining agent introduces tiny and uniform air bubbles into the concrete, improves the freeze-thaw resistance of the concrete, and enhances the workability of the system.

[0030] The graphene oxide used is nanoscale graphene oxide. It is obtained by oxidizing graphite with strong acid. The graphene oxide is mixed with concrete water to lower the freezing temperature of the water.

[0031] Preferably, in the above-mentioned concrete, the animal fat is obtained by grinding sheep wool to 3000 mesh, treating it with an alkaline solution at 40-50℃, and then fermenting it at room temperature. This animal fat forms a waterproof protective film inside the concrete, preventing external moisture from entering and improving the concrete's impermeability.

[0032] The present invention also provides a method for preparing the above-mentioned high-altitude and cold-resistant freeze-thaw concrete, characterized by comprising the following steps: Add fine aggregate, coarse aggregate, and ABS aggregate to a forced mixer and mix continuously for 1-2 minutes. Then add water, silicate binder, plasticizer, composite modified air-entraining agent, animal fat, and graphene oxide and mix continuously for 2-3 minutes. Finally, add modified composite plant powder, modified loofah sponge, and inorganic fiber and mix continuously for 2-3 minutes until the concrete mixture is homogeneous.

[0033] The principle of this invention for high-altitude, cold-resistant freeze-thaw concrete is as follows: By adding modified composite plant powder, modified loofah fiber, and inorganic fibers, the three fibers work synergistically to absorb and retain water within the concrete, preventing plastic shrinkage cracks, increasing tensile strength, and resisting damage caused by large temperature differences at high altitudes. Adding animal fat to the concrete forms a nano-water-resistant film inside, preventing water molecules from entering and thus eliminating conditions for freeze-thaw cycles. Adding ABS aggregate reduces water absorption and crushing index, while also achieving good freeze-thaw resistance. Adding graphene oxide to the concrete, which mixes with water, lowers the freezing point of water and improves freeze-thaw resistance. Adding a composite modified air-entraining agent to the concrete reduces air content and improves stability. The concrete of the present invention can effectively solve the following defects of the prior art: (1) due to the large temperature difference in the plateau, the concrete is prone to freeze-thaw damage in winter due to shrinkage cracks, micro-cracks, and fissures; (2) the surface water of the floor penetrates into the interior of the structure and is prone to freeze-thaw damage; (3) the water absorption rate of commonly used crushed stone aggregate is relatively high and the freeze-thaw resistance is poor; (4) the free water inside the concrete is prone to freeze-thaw damage.
