Abstract

The invention relates to the technical field of concrete mixing, and in particular to a frost-resistant concrete, which is prepared from the following material components in parts by weight: 5 to 15 parts of silica fume, 3 to 10 parts of fly ash, 50 to 80 parts of quartz sand, 8 to 15 parts of diatomite, 30 to 55 parts of cement, 10 to 18 parts of an antifreezing agent and 30 to 60 parts of water,and the antifreezing agent is prepared from the following material components in parts by weight: 25 to 40 parts of acrylic emulsion, 3 to 10 parts of hollow glass beads, 1 to 1.5 parts of tea saponin, 20 to 35 parts of carboxymethyl cellulose sodium, 5 to 15 parts of ethylene glycol, 25 to 40 parts of a water reducing agent and 80 to 150 parts of water. The frost-resistant concrete has frost-resistant and frost-proof properties, and moreover, the product is environment-friendly, and does not affect the quality and normal use of buildings. The invention further provides a processing techniquefor the frost-resistant concrete, which can prepare the frost-resistant concrete with good frost-resistant property.

Description

technical field [0001] The invention relates to the technical field of concrete mixing and processing, in particular to a frost-resistant concrete and a processing technology thereof. Background technique [0002] In building construction, whether it is foundation, pile foundation construction, or house construction, a large amount of concrete is required. In the process of concrete mixing and processing, the mixing and processing of concrete are basically done outdoors. When mixing and processing in winter, due to the increased difference between the temperature of concrete and the outside air temperature, heat exchange will occur between the concrete and the ambient temperature. When the ambient temperature is very low, this heat exchange will quickly reduce the temperature of the concrete. For fresh concrete, the speed of temperature drop directly determines the size of the hydration temperature, the faster the temperature drops, the slower the growth of concrete strengt...
