In order to achieve the above object, the present invention further provides a method for preparing the high strength waterproof concrete, comprising the following steps:
(1) adding the diluted epoxy resin heated to 40-60 ℃ into the fly ash according to the formula amount while stirring, continuously stirring for 10-20 minutes, adding the sand according to the formula amount, stirring for 5-10 minutes, and stirring until the mixture is uniform and stable to obtain a premixed material;
(2) adding the crushed stone and the portland cement into the premixed material, and uniformly mixing and stirring for 20-30 minutes;
(3) fully stirring the hydrophobic component and the dispersing component in the formula amount for 3-5 minutes, adding the water reducing component and the air entraining component in the formula amount, and stirring for 3-5 minutes to prepare the waterproof agent;
(4) and finally, adding the waterproofing agent and the water with the formula ratio, and stirring for 30-60 minutes to obtain the high-strength waterproof concrete.
In the invention, cement is used as a cementing material of high-strength concrete, broken stone is used as a coarse aggregate, sand and fly ash are used as fine aggregates, and diluted epoxy resin and a composite waterproof agent are used as additives to form the high-strength waterproof concrete.
The invention has the following beneficial effects:
1. in the practical application of waterproof concrete, the cost of the waterproof agent is high, but the fly ash and sand are used, and a large amount of middle powder and small particles physically absorb the waterproof agent, so that the using amount of the waterproof agent is increased, and the using efficiency of the waterproof agent is reduced. To solve this problem, highly diluted epoxy resins are added during the preparation of the premix. Unlike common epoxy resin as cementing material in concrete preparation, the diluted epoxy resin is not enough to be used as cementing material, but used as coating material of powder and small particle fine aggregate, and through stirring, coating and curing, the flyash and sand are coated and isolated to isolate the absorption of the waterproofing agent with high cost, reduce the amount of the waterproofing agent and raise the efficiency of the waterproofing agent.
2. The water reducing component is added in the waterproof agent, so that the water reducing effect in the concrete mixing preparation process can be promoted, the drainage efficiency is improved, and in combination with the diluted epoxy resin for coating the isolated powder and the small-particle fine aggregate, the water reducing efficiency can be greatly improved without excessively increasing the water reducing component, and the waterproof efficiency of the prepared concrete is improved.
3. Compared with the traditional silane emulsion water repellent, the fluorine-containing polyhedral oligomeric silsesquioxane F-POSS water repellent and the stearic acid hydroxyl chromium chloride water repellent are selected, and the hydrophobic effect can be improved through hydrophobic groups with higher hydrophobic efficiency and different action mechanisms by means of diversity complementation. The nanometer calcium carbonate with the particle size of 30-50nm and the nanometer calcium carbonate with the particle size of 130-150nm can be used for filling irregular pores with different sizes among particles in concrete, compared with the traditional method of adding the nanometer calcium carbonate with single particle size, the method has the advantages that the efficiency of filling the pores is higher, the cement hydration reaction can be promoted, and the compactness of the cement hydration reaction can be improved. In addition, due to the small size effect of the nanoparticles, a large amount of calcium carbonate particles are attached to the surface of concrete, and the specific surface area of the nanoparticles is increased due to the extremely large specific surface area of the nanoparticles.
4. And finally, the waterproof agent and the nano calcium carbonate with different particle sizes are added in the formula, so that the concrete has good compressive strength, anti-permeability, waterproof and hydrophobic functions, the construction is simplified, the construction period is shortened, the construction cost is reduced, and the service life of the concrete is prolonged.

Comparative example 1
The water repellent formulation and concrete formulation are shown in table one.

Experimental example:
the concrete prepared in examples 1 to 5 and comparative examples 1 to 3 were examined for the penetration height ratio and the 48-hour water absorption ratio according to standard JC474-2008 "mortar and concrete waterproofer".
The compressive strength of the concrete prepared in examples 1 to 5 and comparative examples 1 to 3 after standard curing for 7 days and 28 days was examined according to the GB/T50081-2019 "test method Standard for physical and mechanical Properties of concrete".
TABLE II examination results of the concrete prepared in examples 1 to 5 and comparative examples 1 to 3
Figure BDA0002434389220000091
As can be seen from comparison of example 2 and comparative examples 1 to 3, the concrete containing the water repellent alone, the water repellent alone without the water-reducing component, and the diluted epoxy resin was superior in the water repellency and compressive strength to the comparative example 3 containing no water repellent and diluted epoxy resin. The anti-seepage waterproof effect mainly comes from the waterproof agent, and the improvement of the compressive strength comes from the combined action of the nano calcium carbonate and the diluted epoxy resin in the waterproof agent, and comes from the isolation and wrapping action of the epoxy resin and the filling effect and small-size effect of the nano calcium carbonate with different particle sizes. Compared with the waterproof agent with no water reducing component and the comparative examples 1-2 with diluted epoxy resin, the embodiment 2 with water reducing component and diluted epoxy resin has better anti-seepage, waterproof and anti-compression effects because the water reducing component in the waterproof agent is combined with diluted epoxy resin to coat isolated powder and small-particle fine aggregate, and the water reducing efficiency can be greatly improved without excessively increasing the water reducing component, so that the whole application efficiency of the waterproof agent is improved, and the effect that one is added and the other is more than two is generated.
Comparing the experimental results of examples 1-3, it can be seen that increasing the amount of diluted epoxy resin and water repellent (especially the hydrophobic component of the core component) in the concrete formulation not only increases the water and gas barrier ability of the concrete, but also increases the compressive strength, mainly due to the formulation and cost choices, and example 3, although being the best in effect, is relatively more costly.
Comparing the experimental results of examples 2, 4 and 5, it can be found that the increase of the amount of the diluted epoxy resin can simultaneously improve the water-proof and impervious ability and compressive strength of the prepared concrete under the same formulation of the water-proofing agent. The concrete of example 4 with the best effect has the effect second to that of example 3, and the cost is relatively low, so that the concrete is a more economical and practical proportioning idea. The diluted epoxy resin is not enough to be used as a cementing material, but the fly ash and the sand are wrapped and isolated by stirring, coating and curing, so that the absorption of the diluted epoxy resin on a waterproof agent with higher cost is isolated, the using amount of the waterproof agent is reduced, and the efficiency of the waterproof agent is improved.
