Abstract
The invention discloses a high-tensile-resistance concrete, belonging to the technical field of building materials. The high-tensile-resistance concrete is prepared from the following raw materials in parts by weight: 300-500 parts of cement, 600-800 parts of macadam, 600-800 parts of river sand, 5-15 parts of coal ash, 5-15 parts of ore powder, 5-15 parts of Grace fiber and 200-300 parts of water. The high-tensile-resistance concrete has the advantages of favorable tensile resistance, favorable bending resistance, favorable crack resistance, abundant raw materials, low price, simple production technique and low cost, and is suitable for large-scale production.
Description
Technical field
The present invention relates to a kind of concrete of high tensile, belong to building material technical field.
Background technology
Concrete, referred to as " concrete ", typically refer to and make gelling material with cement, sand, masonry gather materials, and coordinate by a certain percentage with water, through stirring gained.Concrete has abundant raw material, cheap, the simple feature of production technique, make its use range very extensive, not only use in various civil engineering work, be exactly the exploitation, geothermal engineering etc. of shipbuilding, mechanical industry, ocean, concrete is also important material.
Existing concrete material ubiquity tension, folding strength are low, and shock resistance is poor, cannot meet the demand of some special construction field; Meanwhile, existing concrete material is in Mass Concrete, and distress in concrete is comparatively general, have impact on construction quality.
Summary of the invention
The object of the invention is to make up the deficiencies in the prior art, a kind of concrete of high tensile is provided.The concrete tension of high tensile of the present invention, anti-folding, resistance to cleavage are good.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of concrete of high tensile, comprises the raw material of following parts by weight: cement 300 ~ 500 parts, rubble 600 ~ 800 parts, 600 ~ 800 parts, river sand, coal ash 5 ~ 15 parts, breeze 5 ~ 15 parts, Grace fiber 5 ~ 15 parts and 200 ~ 300 parts, water.
On the basis of technique scheme, the present invention can also do following improvement.
Further, the raw material of following parts by weight is comprised: cement 400 parts, rubble 700 parts, 700 parts, river sand, coal ash 10 parts, breeze 10 parts, Grace fiber 10 parts and 250 parts, water.
Further, the index number of described cement is 32.5 or 42.5.
Further, the particle diameter of described rubble is 5 ~ 25cm.
Further, the fineness modulus of described river sand is 3.0 ~ 2.3, and particle diameter is 0.5 ~ 0.35mm.
Further, the particle diameter of described coal ash is 30 ~ 50 μm.
Further, the particle diameter of described breeze is 30 μm.
The invention has the beneficial effects as follows:
(1) the concrete tension of high tensile of the present invention, anti-folding, resistance to cleavage are good.
(2) abundant raw material of the present invention, cheap, production technique is simple, cost is low, be applicable to large-scale production.
