Abstract

The invention provides a concrete additive and relates to the technical field of building engineering materials. The concrete additive comprises, by weight, 15-25 parts of modified concrete, 10-15 parts of gypsum, 5-10 parts of carbon black, 10-20 parts of bentonite, 1-3 parts of silicon dioxide, 10-25 parts of polypropylene fiber, 1-5 parts of a high efficiency slushing agent, 2-4 parts of calcium lignosulfonate, 0.3-0.7 part of hexadecylsulfonic acid sodium salt, 1-9 parts of dispersed latex powder, 0.2-0.6 part of a stabilizer, 1-7 parts of a corrosion inhibitor, 0.5-5 parts of a waterproofing agent, 5-15 parts of an acrylic emulsion and 10-25 parts of deionized water. The invention further provides a preparation method of the concrete additive. The concrete additive has high performance, capabilities of water seepage and compressive deformation, good duration and certain anti-rust function.

Description

[0001] field of invention [0002] The invention belongs to the technical field of building engineering materials, and in particular relates to a concrete additive. Background technique [0003] 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 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 is the most widely used and used building material in civil engineering. [0004] At present, with the development of the economy and the acceleration of urbanization, cement concrete has become the most widely used building material in the world, and there are various requirements for the performance of concrete. Therefore, it is necessary to add...
