Problems solved by technology

[0003] When the existing concrete is used in the northeastern region where the temperature difference changes greatly and in areas with high altitude, the change in the temperature difference will cause the concrete that has been poured soon to undergo freeze-thaw cycles, and the process of multiple freeze-thaw cycles will make the concrete inside The damage accumulates, the strength and bearing capacity gradually decrease, and then there are hazards such as loose cracking

Abstract

The invention discloses freeze-resistant concrete and a preparation method thereof, and relates to the technical field of concrete. Raw materials of the concrete comprise the following materials in parts by weight: 280-310 parts of cement; 85-95 parts of mineral powder; 105-115 parts of fly ashes; 640-680 parts of yellow sand; 1030-1040 parts of crushed stone; 1-3 parts of air-entraining agents; 100-150 parts of first additives; and 180-200 parts of water. The method has the effect of improving the frost resistance of the concrete.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a frost-resistant concrete and a manufacturing method thereof. Background technique [0002] Concrete usually refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate, and then mixed with water (may contain admixtures and admixtures) in a certain proportion and stirred. Concrete has the characteristics of rich raw materials, low price and simple production process, so its consumption is increasing. Concrete is not only used in various civil engineering, but also in shipbuilding, machinery industry, marine development, geothermal engineering, etc. Concrete is also an important material. [0003] When the existing concrete is used in the northeastern region where the temperature difference changes greatly and in areas with high altitude, the change in the temperature difference will cause the concrete that has been poure...
