Abstract
The invention relates to high crack resistance concrete including the following raw material components by weight: 300-330 parts of gravel, 20-40 parts of volcano ash, 200-250 parts of a coarse aggregate, 20-30 parts of a fluorinated alkyl sulfonate, 30-50 parts of trihydroxyethyl methyI ammonium methosulfate salt, 35-40 parts of silica and 300-320 parts of fine sand. The high crack resistance concrete perferably takes raw materials which are help to provide concrete work performance, strength and durability, through the rational collocation of all the components, the high crack resistance concrete preferably has the main characteristics of high admixture ratio and low cementitious material ratio, and the concrete with good workability, high strength, good crack resistance, good impermeability and long service life is ultimately formed.
Description
Technical field
The present invention relates to the cement-base composite material of building material field, specifically one kind improve cement slurry hole
Structure and the high crack-resisting of homogeneity.
Background technology
Engineering crackses have become the focal issue in construction, and the crack problem of wherein mass concrete is particularly subject to close
Note.The factor of impact cracking of reinforced concrete is divided into internal factor and external factor.For larger-size flat board thicker large volume
Concrete (general thickness more than 1m, size in 100m, hereinafter referred to as large-area backplane concrete) for, affect its cracking resistance
Property key factor be the self performance of concrete and foundation restriction power.Large-area backplane xoncrete structure is thicker due to thickness,
Easily form internal-external temperature difference during hydration reaction, produce temperature stress, especially it is subject to ground and internal reinforced binding larger,
Easily form larger shrinkage stress and ftracture, the crack resistance requirement to concrete is very high.
Content of the invention
The technical solution adopted for the present invention to solve the technical problems is: provides a kind of high crack-resisting, it is characterized in that:
Including rubble, volcanic ash, coarse aggregate, fluoroalkylsulfonic acids salt, trihydroxyethyl methyl amine Methylsulfate salt, silica and thin
Sand, its feed components by weight, described rubble 300-330 part, volcanic ash 20-40 part, coarse aggregate 200-250 part, fluorination
Alkylsulfonate 20-30 part, trihydroxyethyl methyl amine Methylsulfate salt 30-50 part, silica 35-40 part and fine sand 300-
320 parts.
Preferably, described high crack-resisting, it is characterized in that: its feed components by weight, comprises rubble 300
Part, 20 parts of volcanic ash, 200 parts of coarse aggregate, 20 parts of fluoroalkylsulfonic acids salt, 30 parts of trihydroxyethyl methyl amine Methylsulfate salt, two
35 parts of silica and 300 parts of fine sand.
Preferably, described high crack-resisting, it is characterized in that: described rubble is by gravelstone and great Shi according to volume ratio
Ratio for 3:7 combines, and the mould degree of counting accurately of rubble is 1.5.
Preferably, described high crack-resisting it is characterised in that: described trihydroxyethyl methyl amine Methylsulfate salt is
Polycarboxylic-acid retardation setting type high-performance trihydroxyethyl methyl amine Methylsulfate salt.
Preferably, described high crack-resisting, it is characterized in that being prepared by following methods:
(1) good various raw materials are configured by weight ratio；
(2) the various raw materials having configured are added in stirred reactor one by one, be evacuated to 0.2mpa, be 60rpm in rotating speed
Under conditions of stir 2h, you can prepared high crack-resisting.
The concrete of the present invention is preferred beneficial for providing the raw material of working performance of concrete, intensity and endurance quality, leads to
Cross the reasonably combined of each component, with high admixture usage ratio, low-cementitious material usage ratio as principal character, ultimately form work
The property made is good, intensity is high, crack resistance is good, the concrete of impervious good and life-span length.
