Abstract

The invention discloses concrete for high-rise floor slabs. The concrete is formed by evenly mixing the following raw materials of, by weight, 170-180 kg / m<3> of water, 230-250 kg / m<3> of cement, 50-60 kg / m<3> of coal ash, 52-62 kg / m<3> of mineral powder, 785-795 kg / m<3> of sand, 1050-1060 kg / m<3> of fine stone, 110-220 kg / m<3> of silicon powder and 4.2-5.2 kg / m<3> of additives. The concrete for high-rise floor slabs has the advantages of being reasonable in structure and wide in application range.

Description

technical field [0001] The invention relates to the technical field of concrete for design buildings, in particular to a kind of concrete for high-rise floors. Background technique [0002] Concrete is a general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. concrete. Concrete is the most widely used and used building material in civil engineering. Design and manufacture concrete according to the predetermined performance, and develop new varieties of lightweight, high-strength, and multi-functional concrete. [0003] The existing concrete mix design is unreasonable, cannot be applied to the needs of existing production and life, and the cost is high. Conten...
