Abstract

The invention discloses a concrete additive and concrete thereof, belonging to the technical field of concrete. The concrete additive comprises the following raw materials by weight: 5 to 15 parts of bentonite, 1 to 9 parts of silicon dioxide powder, 5 to 15 parts of polypropylene fiber, 2 to 8 parts of calcium powder, 2 to 8 parts of calcium lignosulphonate powder, 1 to 9 parts of dispersion emulsion powder and 5 to 15 parts of an acrylic emulsion. The concrete additive provided by the invention can improve toughness, compressive strength and service life of the concrete; and the concrete prepared by using the concrete additive in the invention has the advantages of good tensile, flexural and anticracking performances, low price, simple production process, low cost, and applicability to large-scale production.

Description

technical field [0001] The invention relates to a concrete additive and concrete thereof, belonging to the technical field of concrete. Background technique [0002] Concrete, referred to as "concrete" for short, usually refers to using cement as the cementitious material, sand and stone as the aggregate, mixed with water in a certain proportion, and mixed. Concrete has the characteristics of rich raw materials, low price and simple production process, which makes it widely used. It is not only used in various civil engineering, but also in shipbuilding, machinery industry, marine development, geothermal engineering, etc. Concrete is also an important material . [0003] In practical engineering applications, concrete is often exposed to various harsh environments, such as the intrusion of corrosive media around the environment, changes in ambient temperature and humidity, freeze-thaw cycle damage, and some concrete projects are often subject to heavy load wear, etc. These ...
