Abstract
The invention discloses a kind of impervious cracking resistance machine-made sand concretes, it is characterized in that, it is calculated according to components by weight percent as follows: 450-480 parts of cement, 80-130 parts of coarse aggregate, 60-80 parts of fine aggregate, 60-90 parts of ultra fine sand, 650-750 parts of Machine-made Sand, 90-120 parts of diamond dust, 1100-1130 parts of rubble, impervious powder 10-18 parts, 24-32 parts of economization agent, 18-23 parts of water-reducing agent, 0-8 parts of defoaming agent.Beneficial effects of the present invention: high-performance is prepared with impervious agent, Machine-made Sand and coagulates the leading developing direction that soil is Concrete technical field, meet impervious, waterproof requirement, the present invention solves that river sand resource is in short supply, ensure that concrete engineering construction make smooth advances and concrete structure quality is excellent and convenient construction, low in cost.
Description
Technical field
Present invention relates particularly to a kind of concrete, and in particular to arrives impervious cracking resistance machine-made sand concrete.Belong to concrete skill
Art field.
Background technique
Water-tight concrete is generally used for the bottom plate and side wall of the basement bottom boards of civil buildings, wallboard and subway engineering,
Other than the intensity requirement for meeting concrete, impervious, waterproof performance is the performance of the most important thing of this kind of concrete.Both it requires to mix
Solidifying soil itself has good anti-permeability performance, while also requiring to pour the water-tight concrete entity structure finished and cannot split in the presence of nocuousness
Seam；Otherwise concrete impermeability is good again, if there are perforative harmful cracks, concrete solids for concrete solid structure
Structure can not meet impervious, waterproof requirement.Water is all-pervasive.The some surface defects of concrete such as honeycomb, hole, fiber crops
Face, dew muscle etc., all easily cause percolating water.Impermeability is the most important index of concrete durability, has reacted the hole knot of concrete
Structure and compactness are the bases of the performances such as anti-erosion, anti-carbonation.
Summary of the invention
In view of the above-mentioned problems of the prior art, the object of the present invention is to provide a kind of machine-made sand concrete compositions.
To achieve the above object, the technical solution adopted by the present invention is that: according to components by weight percent calculate it is as follows: cement 450-
480 parts, 80-130 parts of coarse aggregate, 60-80 parts of fine aggregate, 60-90 parts of ultra fine sand, 650-750 parts of Machine-made Sand, diamond dust 90-120
Part, 1100-1130 parts of rubble, impervious powder 10-18 parts, 24-32 parts of economization agent, 18-23 parts of water-reducing agent, 0-8 parts of defoaming agent.
Preferably, the coarse aggregate preferably uses continuous grading, and maximum particle diameter is not preferably greater than 40mm, and clay content must not be big
In 1.0%, clod content is not greater than 0.5%.
Preferably, the clay content of the fine aggregate is not greater than 3.0%, and clod content is not greater than 1.0%.
Preferably, the cement is portland cement, but its intensity is not less than 42.5 strength grades.
Preferably, the water-reducing agent is polycarboxylate water-reducer, solid content >=30%.
Preferably, the impervious powder is less than 100nm mainly by the nano silica (SiO2H2O) containing the crystallization water
Particle, ratio > 50%.
Preferably, the seepage-resistant grade is not less than P6 grades.
Compared with the prior art, beneficial effects of the present invention: preparing high-performance to coagulate soil with impervious agent, Machine-made Sand is concrete
One leading developing direction in preparation technique field, meets impervious, waterproof requirement, and it is in short supply that the present invention solves river sand resource,
Ensure that concrete engineering construction make smooth advances and concrete structure quality is excellent and convenient construction, low in cost.
