Anti-freezing concrete

Abstract

The invention relates to anti-freezing concrete and belongs to the field of concrete. The technical problem to be solved by the invention is to provide the concrete with better anti-freezing performance. The anti-freezing concrete comprises the following components in parts by weight: 325-350 parts of cement, 320-800 parts of sand, 435-1085 parts of gravel, 70-95 parts of preservative and 22-26 parts of TS type anti-freezing agent, wherein the preservative is at least one of 75-grade pulverized mineral powder, fly ash and silica fume. The anti-freezing concrete has the advantages of better anti-freezing performance, low cost and simple construction method, thereby providing a new choice for the field and having broad application prospects.

Description

technical field [0001] The invention relates to antifreeze concrete and belongs to the field of concrete. Background technique [0002] As a building material, concrete has the advantages of simple construction, high strength, good stability, good durability, and low maintenance cost, and has been widely used in construction. Our country has a vast territory, and the climate and environment of different regions are quite different. In the vast western and northern regions of our country, the temperature in winter is low, and ordinary concrete is prone to freezing cracks or false coagulation when pouring, which affects the quality of construction. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a concrete with better antifreeze performance. [0004] The antifreeze concrete of the present invention comprises the following components by weight: 325-350 parts of cement, 320-800 parts of sand, 435-1085 parts of gravel, 70-95...
