Abstract
The invention discloses a kind of water-tight concrete mixture and its construction methods, it solves and contains a large amount of chlorion in marine environment, the reinforcing bar and concrete of inside concrete can be caused to damage in itself, the problem of influencing the using effect of water-tight concrete, its key points of the technical solution are that a kind of water-tight concrete mixture, include following raw material, the mass fraction of each raw material and each raw material is as follows：250 ~ 420 parts of portland cement, 65 ~ 80 parts of flyash, 650 ~ 850 parts of sand, 1000 ~ 1080 parts of rubble, 5 ~ 10 parts of water-reducing agent, 13 ~ 29 parts of calcium sulphoaluminate class swelling agent, 1 ~ 3 part of other auxiliary agents, 160 ~ 190 parts of water, the concrete obtained after curing have chlorion preferable tolerance.
Description
Technical field
The present invention relates to concrete, more particularly to a kind of water-tight concrete mixture and preparation method thereof.
Background technology
Concrete refers generally to using cement as major gelled material, and water, sand, stone, mix when necessary chemical admixture and
Mineral admixture is coordinated by proper proportion, the artificial stone formed by uniform stirring, closely knit molding and maintenance hardening.Coagulation
Soil good mechanical property, economy and is fitted environment as the construction material that dosage in the world is big, use scope is wide
Answering property has obtained extensive development in various countries and area, with the development of society, people propose higher to the performance of building
Requirement.
