preparation example Construction

[0026] The embodiment of the present invention also provides a kind of preparation technology of concrete, comprises the following steps:

[0027] S1. Mix 5-20 parts of hollow glass microspheres and 3-15 parts of polypropylene fibers at a temperature of 50-70° C. to obtain a first mixed powder.

[0028] First mix the functional material composed of hollow glass microspheres and polypropylene fibers at a higher temperature, so that the polypropylene fibers can be coated on the surface of the hollow glass microspheres, increasing the intermolecular force and effectively reducing the size of the hollow glass. The distance between the microbead molecules enhances its thermal insulation and sound insulation effect. The mixing process needs to be controlled within a certain range. If the temperature is too low, it is not conducive to ensuring the uniformity of mixing. If the temperature is too high, it will easily cause side reactions between raw materials and affect the effect of h...

Embodiment 1

[0034] The present embodiment provides a kind of preparation technology of concrete, and it comprises the following steps:

[0035] Mix 5 parts of hollow glass microspheres and 3 parts of polypropylene fiber at a temperature of 50°C to obtain the first mixed powder; mix 30 parts of metamorphic marble powder, 20 parts of cement, 15 parts of sand, 2 parts of water and the first Blend the powders to mix.

[0036] This embodiment provides a concrete, which is prepared by the above concrete preparation process.

Embodiment 2

[0038] The present embodiment provides a kind of preparation technology of concrete, and it comprises the following steps:

[0039] Mix 20 parts of hollow glass microspheres and 15 parts of polypropylene fiber at a temperature of 70°C to obtain the first mixed powder; mix 60 parts of metamorphic marble powder, 50 parts of cement, 35 parts of sand, 10 parts of water, 2 parts Lignosulfonate (water reducing agent), 3 parts of water-resistant blending powder and the first mixed powder are mixed. Among them, the water-resistant blending powder includes 2.25 parts of water-resistant rubber powder and 0.75 parts of polyurethane.

[0040] This embodiment provides a concrete, which is prepared by the above concrete preparation process.

Abstract

The invention discloses a concrete, and a formula and a preparation method thereof, and belongs to the technical field of concrete. The concrete comprises, by weight, 30 to 60 parts of modified marble powder, 20 to 50 parts of cement, 15 to 35 parts of sand, 2 to 10 parts of water, 5 to 20 parts of hollow glass micro bead, and 3 to 15 parts of polypropylene fiber. According to the preparation method, full utilization of modified marble leftover materials is realized, and the cost of a base material is reduced greatly; hollow glass micro bead and polypropylene fiber are added into the base material, combination of the hollow glass micro bead and polypropylene fiber is capable of improving the thermal and sound insulation effect of concrete. According to the preparation method, hollow glass micro bead is mixed with polypropylene fiber firstly at a relatively high temperature, and an obtained mixture is mixed with the other ingredients so as to obtain the uniformly mixed multifunctional concrete. The preparation method is simple, and is convenient for industrial applications. The concrete prepared via the preparation method is high in compressive strength, and excellent in thermal and sound insulation performance.

Description

technical field [0001] The invention relates to the technical field of concrete, and in particular to concrete, its formula and preparation process. Background technique [0002] Concrete is one of the most important civil engineering materials today. It is composed of cementitious materials, granular aggregates (also known as aggregates), water, and additives and admixtures added when necessary, prepared in a certain proportion, uniformly stirred, densely formed, cured and hardened. artificial stone. Concrete has the characteristics of rich raw materials, low price and simple production process, so its consumption is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. [0003] However, the existing concrete has problems such as that the mechanical strength cannot meet the technical requirements or the manufacturing cost is relatively high. Contents of the invention [0...
