Abstract

The invention discloses a kind of concrete formulation, it is related to building material field, land plaster, agstone, alum powder have been used in the concrete formulation, by being reacted with the cement in concrete, water hydratable to produce the crystallization that volume becomes big, so as to cause volume of concrete to expand, certain prestressing force is produced, to help control Shrinkage Cracking of Concrete.The steel wire and polypropylene fibre of random distribution are also mixed with concrete, the extension of inside concrete microcrack and the formation of macrocrack can effectively be hindered, tension, bending resistance, shock resistance and the anti-fatigue performance of concrete are significantly improved, there is preferable ductility.

Description

A kind of concrete formulation

Technical field

The present invention relates to building material field, it is more particularly related to a kind of concrete formulation.

Background technology

Concrete typically refers to make binder materials with cement, and sand, masonry gather materials, and coordinate by a certain percentage with water, warp Stir the construction material of gained.Concrete has abundant raw material, cheap, the characteristics of simple production process, it is used model Enclose quite varied, not only used in various civil engineerings, be exactly shipbuilding industry, mechanical industry, the exploitation of ocean, geothermal engineering Deng concrete is also important material.

Currently in order to improving compensating shrinkage of concrete ability, the materials such as calcium sulphoaluminate are often added in concrete formulation. Although Shrinkage Cracking of Concrete can be alleviated to a certain extent, the overall tensile strength of concrete and shock resistance can not be improved Performance.

The content of the invention

Problem to be solved by this invention is to provide a kind of impact-resistant concrete formulation.

To achieve these goals, the technical scheme taken of the present invention is：A kind of concrete formulation, it is characterised in that should Concrete includes following component：150~190 parts of water, 130~220 parts of cement, 260~290 parts of sand, 420~510 parts of stone, steel 45~65 parts of silk, 20~35 parts of polypropylene fibre, 8~12 parts of land plaster, 11~16 parts of agstone, 6~9 parts of alum powder.

Preferably, the particle diameter of the stone is 22~32mm.

Preferably, the steel wire is by carbon structure steel making, and between 1~3mm, steel wire length is not less than steel wire diameter 20cm。

Preferably, the granularity of the land plaster is 110~210 mesh, and the granularity of agstone is 110~210 mesh, alum powder Granularity be 110~210 mesh.

Beneficial effect：Land plaster, agstone, alum powder have been used in the concrete formulation, by with concrete Cement, water hydratable are reacted to produce the crystallization that volume becomes big, so as to cause volume of concrete to expand, produce certain prestressing force, with Help control Shrinkage Cracking of Concrete.The steel wire and polypropylene fibre of random distribution are also mixed with concrete, can be effective Ground hinders the extension of inside concrete microcrack and the formation of macrocrack, significantly improves the tension of concrete, bending resistance, anti- Impact and anti-fatigue performance, have preferable ductility.

Embodiment

Embodiment 1：

The concrete includes following component：155 parts of water, 135 parts of cement, 265 parts of sand, 450 parts of stone, 45 parts of steel wire, gather 25 parts of tacryl, 8 parts of land plaster, 11 parts of agstone, 6 parts of alum powder.The particle diameter of stone is 25mm.Steel wire is by carbon structure Steel making, steel wire diameter 1mm, steel wire length are not less than 20cm.The granularity of land plaster is 120 mesh, and the granularity of agstone is 120 mesh, the granularity of alum powder is 120 mesh.

Embodiment 2：

The concrete includes following component：165 parts of water, 185 parts of cement, 275 parts of sand, 480 parts of stone, 55 parts of steel wire, gather 30 parts of tacryl, 10 parts of land plaster, 13 parts of agstone, 8 parts of alum powder.The particle diameter of stone is 28mm.Steel wire is by carbon knot Structure steel making, steel wire diameter 2mm, steel wire length are not less than 20cm.The granularity of land plaster is 160 mesh, the granularity of agstone For 160 mesh, the granularity of alum powder is 160 mesh.

Embodiment 3：

The concrete includes following component：185 parts of water, 215 parts of cement, 285 parts of sand, 500 parts of stone, 65 parts of steel wire, gather 35 parts of tacryl, 12 parts of land plaster, 16 parts of agstone, 9 parts of alum powder.The particle diameter of stone is 32mm.Steel wire is by carbon knot Structure steel making, steel wire diameter 3mm, steel wire length are not less than 20cm.The granularity of land plaster is 200 mesh, the granularity of agstone For 200 mesh, the granularity of alum powder is 200 mesh.

Land plaster, agstone, alum powder have been used in the concrete formulation, by with the cement in concrete, Shui Shui Change reaction to produce the crystallization that volume becomes big, so as to cause volume of concrete to expand, produce certain prestressing force, it is mixed to help control Coagulate native shrinkage cracking.The steel wire and polypropylene fibre of random distribution are also mixed with concrete, can effectively hinder coagulation The native internal extension of microcrack and the formation of macrocrack, significantly improve the tension of concrete, bending resistance, shock resistance and anti-tired Labor performance, there is preferable ductility.

Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair The equivalent structure or equivalent flow conversion that bright description is made, or directly or indirectly it is used in other related technology necks Domain, it is included within the scope of the present invention.
