Abstract
The invention discloses high-strength waterproof concrete and a preparation method thereof, wherein the preparation method comprises the following steps: cement, coarse aggregate, fine aggregate, kaolin, attapulgite, sodium lignosulfonate, ethylene Propylene Diene Monomer (EPDM) powder, waste sisal fiber, graphene fiber and amino-terminated hyperbranched polysiloxane HPSi-NH 2 1,3, 5-triglycidyl-S-triazinetrione, tricyclo (5.2.1) methacrylate.02,6]Decan-8-yl ester/7-fluoro-5-oxo-8- (4- (2-propenyl) -1-piperazinyl) -5H-thiazolo [3,2-a]Quinoline-4-carboxylic acid/N-vinylcarbazole/vinyltriethoxysilane copolymer, water. The concrete has the advantages of remarkable waterproof effect, good durability, high strength and sufficient anti-seepage and anti-cracking performances.
Description
Technical Field
The invention relates to the technical field of building materials, in particular to high-strength waterproof concrete and a preparation method thereof.
Background
The concrete is not separated from the national infrastructure projects of buildings, municipal administration, traffic, water conservancy and the like in all countries of the world, and plays a non-negligible role in construction. The artificial stone is prepared from cementing material, granular aggregate (also called aggregate), water, and additives and admixtures added if necessary according to a certain proportion through uniformly stirring, compacting, shaping, curing and hardening. The concrete has the characteristics of rich raw materials, low price, simple production process, larger and larger consumption, high compressive strength, good durability, wide strength grade range and the like.
The existing common concrete material cannot meet the engineering requirement of high strength. In wet and rainy areas or under water for civil engineering construction, the water resistance of concrete is one of the most important investigation indexes. Due to the characteristics of the structure of the conventional common concrete material, leakage phenomena often occur in the use process, especially for underground and underwater structural engineering, which seriously affects and restricts the application of the concrete material.
