Leakage-proof concrete

Abstract

The invention discloses leakage-proof concrete, and relates to concrete for preventing leakage. The leakage-proof concrete comprises cement, sand, stones and water, and the concrete is characterized in that the concrete is obtained by mixing of a fiber filament and bentonite; and the bentonite accounts for 5-15% of concrete components, and the fiber filament accounts for 5-10%of the concrete components; the bentonite is sodium bentonite, and the fiber filament is plant fibers such as sisal fibers and flax fibers; and the length of the fiber filament is 5-50mm. The leakage-proof concrete provided by the invention has the characteristics of reasonable components, a wide application range, an excellent effect and the like, and therefore the leakage-proof concrete belongs to novel leakage-proof concrete which integrates economy and practicability.

Description

technical field [0001] The anti-leakage concrete of the invention relates to a kind of concrete for preventing leakage. Background technique [0002] As a common building material in the construction industry, cement is widely used in many places such as buildings, bridges, and floors; after long-term use, the cement floor of the underground garage often cracks, and groundwater will slowly seep upward through the gaps. The main reason for this phenomenon on the ground is that the ground is cracked due to repeated rolling by vehicles and the foundation is not stable, and when the components of the concrete poured into the ground are unreasonable, cracks appear. After cracking, the crack will only gradually increase, and will not heal. [0003] Due to the unreasonable mix ratio design of concrete (water-cement ratio design, aggregate gradation, admixture dosage, type and dosage of mineral admixture, etc.), the rheological properties of concrete are not good, and a dense inter...

Problems solved by technology

[0003] Due to the unreasonable mix ratio design of concrete (water-cement ratio design, aggregate gradation, admixture dosage, type and dosage of mineral admixture, etc.), the rheological properties of concrete are not good, and a dense internal structure cannot be formed. Or the honeycomb, pockmarked surface, and holes caused by uneven vibration during construction, or the cracks in the concrete due to poor maintenance after pouring, resulting in structural leakage
