Problems solved by technology

The photovoltaic pavement prepared by this invention has poor compressive strength and flexural strength and short service life
[0004] The mechanical properties and durability of concrete will be affected by factors such as chloride salts, chemical corrosion, carbonization and microorganisms in the environment. At present, concrete still has shortcomings such as poor strength, low frost resistance, large drying shrinkage, and easy cracking. It is used in Transparent concrete on photovoltaic roads has high requirements on durability. Therefore, it is urgent to design a new type of durable concrete with high strength, good frost resistance, small drying shrinkage, not easy to crack, and heat resistance to meet the needs of high-quality construction projects. The need to become a technical problem that needs to be solved urgently in this field

preparation example Construction

[0032] As a kind of preferred preparation method, the preparation method of described a kind of antibacterial concrete comprises the steps:

[0033] S1. Weigh all the raw materials according to the weight percentage, mix the weighed epoxy resin, curing agent, polyethylene glycol, and ethanolamine, heat to 150-180°C, and stir to make the epoxy resin, curing agent, Polyethylene glycol and ethanolamine are completely dissolved to form a transparent solution to obtain a resin compound;

[0034] S2. Put the titanium dioxide in the weight percentage into the resin glue and stir for 10-30min, mix evenly to make resin glue mortar;

[0035] S3. mixing the glass particles in the weight percentage into the resin mortar and stirring for 30-60min to obtain transparent concrete;

[0036] S4. The transparent concrete is introduced into a mold for compaction, placed at room temperature for curing and molding, and the durable concrete specimen is obtained after demoulding.

[0037] The prese...

Embodiment 1

[0039] A highly durable concrete made from the following components by weight percentage:

[0040]

[0041] The epoxy resin is formed by mixing epoxy resin AFG-90 and epoxy resin TDE-85 in a weight ratio of 1:1; the curing agent is cyclohexanone peroxide; the polyethylene glycol is preferably polyethylene glycol Alcohol 20000 and polyethylene glycol 400 are mixed in a weight ratio of 1:0.1; the ethanolamine is preferably prepared by mixing diethanolamine and triethanolamine in a weight ratio of 1:0.1.

[0042] The preparation method of durable concrete described in the present embodiment comprises the steps:

[0043] S1. Weigh all the raw materials according to the weight percentage, mix the weighed epoxy resin, curing agent, polyethylene glycol, and ethanolamine, heat to 150°C, and stir to make the epoxy resin, curing agent, polyethylene glycol Glycol and ethanolamine are completely dissolved to form a transparent solution to obtain a resin compound;

[0044] S2. Put the t...

Embodiment 2

[0048] This embodiment provides a high-durability concrete. Compared with Embodiment 1, the difference is that it is made of the following components in weight percentage: 10% epoxy resin; 5% curing agent; 70% glass particles; titanium dioxide 5%; polyethylene glycol 5%; ethanolamine 5%.

Abstract

The invention discloses a high-durability concrete and a preparation method thereof, which is made of the following components in weight percent: 5-20% of epoxy resin, 1-5% of curing agent, 60-80% of glass particles, and 5-10% of titanium dioxide %, polyethylene glycol 5‑10%, ethanolamine 1‑5%. Due to the interaction forces such as ionic bond, covalent bond, hydrogen bond and van der Waals force between the components of the present invention, the internal structure of the concrete is more stable, the durability of the concrete such as compression resistance, corrosion resistance, and frost resistance is improved, and the increase in The toughness and anti-radiation performance of concrete can improve the service life of concrete and make the concrete not easy to crack and have good workability. Moreover, the preparation process is simple and the cost is low.

Description

technical field [0001] The invention relates to the field of polymer material science, in particular to a high-durability concrete and a preparation method thereof. Background technique [0002] The load-bearing high-speed photovoltaic pavement converts the collected solar energy into electrical energy, which has been widely studied in recent years. The top layer of the photovoltaic road is transparent concrete similar to frosted glass, which allows sunlight to pass through the solar cells below to convert light energy into electrical energy. . At present, there are three main forms of transparent concrete preparation in China. One is to prepare transparent concrete by pouring cement mortar outside the prefabricated resin block; the other is to pour cement or asphalt concrete around the fixed optical fiber to prepare light-conducting concrete; It is mixed with cement as a binder and aggregate to prepare translucent concrete. The light transmittance of concrete prepared by ...
