Abstract
The invention discloses anti-crack type concrete. The anti-crack type concrete comprises the following ingredients in parts by weight: 50-70 parts of cement mortar, 17-23 parts of waste bricks, 11-15 parts of stones, 15-20 parts of reinforced fibers, 11-12 parts of aggregate and 1-3 parts of a cement foaming agent, wherein the cement foaming agent comprises the following ingredients in parts by weight: 5-7 parts of sand grains, 5-10 parts of calcium aluminate cement, 10-13 parts of limestone, 12-18 parts of coal ash, 8-10 parts of redispersible latex powder and 10-12 parts of bauxite. The anti-crack type concrete adopts the cement mortar containing the redispersible latex powder as a main ingredient, strength is much higher than that of the conventional cement mortar, no crack is produced, anti-crack effect is good, water retaining property is excellent, the reinforced fibers are disorderly distributed in the cement mortar, concrete is assisted to bear tensile stress and transmit the tensile stress, and extension of a macrorack is prevented, so that breaking strength and toughness of concrete are improved; and aggregate and stones are added, so that strength of the concrete can be enhanced, and influence of earth to the concrete is reduced; besides, the waste brick is extensive in source and low in price, and resources are saved.
Description
Technical field
The present invention relates to a kind of concrete, particularly relate to a kind of crack resistance type concrete.
Background technology
Concrete refers to be cemented to gathering materials the general designation of the engineered composite material of entirety by Binder Materials.Fast development along with real estate industry of current China, demand for concrete is the most increasing, various performances simultaneously for concrete are the most increasingly paid attention to, mix Design is a job critically important in concrete works, and it directly influences the smooth construction of concrete, the quality of concrete works and the cost of concrete works.The intensity of existing mixed earth is little, easy to crack.Therefore, the present invention proposes a kind of new technical scheme.
Summary of the invention
For solving the problems referred to above, the present invention provides a kind of crack resistance type concrete, and intensity is big, the most easy to crack.
A kind of crack resistance type concrete, it includes each composition of following weight portion: the cement mortar of 50-70 part, the useless brick of 17-23 part, the stone of 11-15 part, the reinforcing fibre of 15-20 part, the aggregate of 11-12 part and the cement blowing agent of 1-3 part, described cement mortar includes each composition of following weight portion: the grains of sand of 5-7 part, the aluminous cement of 5-10 part, the limestone of 10-13 part, the flyash of 12-18 part, 8-10 part redispersable latex powder and 10-12 part bauxite.
Described redispersable latex powder is vinylacetate and acrylate and higher aliphatic vinyl acetate ternary polymerization rubber powder.
It includes each composition of following weight portion: the cement mortar of 60 parts, the useless brick of 20 parts, the stone of 13 parts, the reinforcing fibre of 18 parts, the aggregate of 11 parts and the cement blowing agent of 2 parts, described cement mortar includes each composition of following weight portion: the grains of sand of 6 parts, the aluminous cement of 8 parts, the limestone of 11 parts, the flyash of 15 parts, 9 parts of redispersable latex powders and 11 parts of bauxites.
Beneficial effects of the present invention: using the cement mortar containing redispersable latex powder is major ingredient, intensity is significantly larger than traditional cements mortar, and flawless, effect of anti-cracking is good, water-retaining property is excellent, by the most disorderly and the most unsystematic distribution of reinforcing fibre in cement mortar, assists concrete to undertake tension and transmission tension, stop the extension of macrocrack, thus improve concrete flexural strength and toughness；Addition by aggregate and stone can increase the intensity of concrete, reduces the earth impact on concrete, and give up brick wide material sources, cheap, economizes on resources.
