Problems solved by technology
[0003] As one of the necessary additives to concrete, the amount of aggregate used is very large, and the natural aggregate is over-exploited, so that its quality cannot meet the needs of existing concrete production. At present, the concrete still has poor strength, low frost resistance, large drying shrinkage, and is prone to Insufficiency such as cracking

Embodiment Construction
[0015] The described high temperature resistant concrete is characterized in that it is made of the following raw materials in parts by weight: cement 105, yellow sand 95, sodium lauryl sulfonate 9, heavy calcium carbonate 7, quartz sand 25, calcium formate 16. Bentonite 81, calcium lignosulfonate 14, polycrystalline mullite fiber 25, asphalt road waste 95, waste clothes 35, additives 4. appropriate amount of water.
[0016] The auxiliary agent is made of the following raw materials by weight: kaolin 8, tung oil 2, urea 11, neem bark 9, aluminum hydroxide 13, waste glass 7, sodium dodecyl benzene sulfonate 0.03, magnesium powder 0.02, super Micro-wax powder 0.3, pitch 2, rose essential oil 0.03, the preparation method is to pulverize and mix the materials, add appropriate amount of water, stir for 30-40 minutes, granulate, the particle size of the ball is 2-5mm, and it is obtained by drying.
[0017] The production method includes the following steps:
[0018] (1) After cleaning the...

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 [0001] The invention relates to the technical field of building concrete, in particular to a high-temperature resistant concrete and a manufacturing method thereof. Background technique [0002] Concrete is usually made of cement as a cementing material, sand and stone as aggregates, mixed with water (which may contain additives and admixtures) in a certain proportion, and the cement concrete obtained by mixing is also called ordinary concrete. It has the advantages of molding, low energy consumption, good durability, low price, and can be made into various load-bearing mechanisms in combination with steel. It is the most widely used building material in modern times and plays a very important role in the development of human society. [0003] As one of the necessary additives for concrete, the amount of aggregate is very large. Natural aggregate is over-exploited, making its quality unable to meet the needs of existing concrete production. At present, concrete stil...
