Abstract
The invention discloses a high temperature resistant concrete. The high temperature resistant concrete is prepared by using the following raw materials, by weight, 105-125 parts of cement, 90-115 parts of , 9-13 parts of sodium dodecanesulphonate, 7-9 parts of heavy calcium carbonate, 25-35 parts of quartz sand, 12-16 parts of calcium formate, 80-100 parts of bentonite, 11-14 parts of calcium lignin sulphonate, 25-30 parts of polycrystalline mullite fibers, 95-115 parts of blacktop waste residues, 35-50 parts of waste clothes, 4-7 parts of an assistant and a proper amount of water. The aggregate of the concrete prepared in the invention contains the blacktop waste residues, so the consumption of natural sandstones is reduced, and the production cost is reduced; and the polycrystalline mullite fibers and waste clothes are added to the raw materials, so the toughness and the heat insulation performance of the concrete are increased, thereby the concrete prepared in the invention has the advantages of unlikely cracking, good workability, high temperature resistance, improved pore structure and pore gradation, and improved impervious capability.
Description
Technical field
The present invention relates to building concrete technical field, be specifically related to a kind of refractory concrete and preparation method thereof.
Background technology
Concrete is normally made gelling material with cement, sand, masonry gather materials, coordinate by a certain percentage with water (can contain admixture and adulterant), through stirring and cement concrete, also claim normal concrete, it has advantages of that easy-formation, energy consumption are low, good endurance, low price and be combined and can be made into various support mechanisms with steel, is contemporary most widely used material of construction, and the development of human society is played a very important role
The consumption that gathers materials that one of must addition material as concrete is very large, and natural aggregate overexploitation, makes it quality and also cannot meet the demand that existing concrete is produced, and concrete also exists intensity difference at present, frost resistance is low, dry shrinkage is large, and the deficiencies such as cracking easily occur.Therefore, develop various artificial aggregates and find suitable substitute material, thereby develop a kind of high strength, frost resistance is good, dry shrinkage is little, the new concrete of not easy to crack, the antibacterial function such as heat-resisting, become this area and be badly in need of the technical barrier solving to meet the needs of high quality construction project.
In recent years, along with growth in the living standard and social progress, the various solid wastes that people's daily life and Industrial processes produce and urban construction are removed and are remake the solid waste brought etc. and perplexing always resident's living environment, and the processing of the waste and old clothes that more particularly can not continue to wear is a difficult problem always.The present invention adds in concrete solid waste as starting material, has realized the cyclic utilization of waste, has reduced the pollution to environment, meets strategy of sustainable development requirement.
Summary of the invention
Object of the present invention is just to provide a kind of refractory concrete and preparation method thereof, to overcome the deficiencies in the prior art.
The object of the present invention is achieved like this:
