Abstract

The invention discloses a non-fired concrete brick, which is uniformly mixed with the following raw materials: ordinary silicon cement 20-30, fly ash 15-25, industrial waste slag 35-50, sand 5-15, Admixture 0.075~0.125, straw 1~5, water 15~20, the present invention can be applied to cast-in-situ concrete such as foundation, beam, column, frame, bridge of high-rise building, and the integral pouring of T-shaped joint. It can guarantee the quality of the overall building and meet the building standards.

Description

technical field [0001] The invention relates to the technical field of concrete for design and construction, and in particular relates to an unfired concrete brick. 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. C...
