Abstract

The invention discloses light-weight high-strength concrete. The concrete is composed of the following raw materials in parts by weight: 210-300 parts of cement, 10-18 parts of yellow sand, 5-7 partsof carbon powder, 1-4 parts of calcium carbonate, 0.05-0.2 part of zinc sulfate, 1-2 parts of a polycarboxylic acid high-efficiency water reducing agent and 1.7-3.4 parts of polypropylene fibers. According to the lightweight high-strength concrete provided by the invention, through activation, the obtained light-weight concrete has engineering value of concrete and extremely high strength.

Description

technical field [0001] The invention relates to the construction field, in particular to a lightweight high-strength concrete. Background technique [0002] Concrete, referred to as "concrete" for short: refers to the collective name of engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to cement as cementing material, sand and stone as aggregate; mixed with water (with or without admixtures and admixtures) in a certain proportion, and obtained by stirring, molding and curing. Cement concrete, also known as ordinary concrete, is widely used in civil engineering. However, the existing concrete imposes a strong burden on construction due to its heavy weight. Contents of the invention [0003] The object of the present invention is to provide a lightweight high-strength concrete to solve the above-mentioned technical defects. [0004] To achieve the above object, the present ...
