Abstract

The invention discloses a fiber-enhanced cement admixture, and belongs to the field of building materials. The fiber-enhanced cement admixture is prepared from cement clinkers, synthetic fibers or plant fibers, coke slag, polymer emulsion, a wooden-calcium water reducing agent, silica fume, a retarder, an air entraining agent and a lubricating agent. According to the fiber-enhanced cement admixture, the ratio of conventional aggregates is reduced; the aggregates are synthesized by the coke slag and the silica fume, so that the forming strength of the admixture is guaranteed; furthermore, the mass of the admixture is greatly reduced, the construction intensity is reduced, and transportation and manufacturing are facilitated; by the adding of the fiber material, while the mass of the admixture is not greatly increased, the crack resistance and the impact resistance of the admixture are improved.

Description

technical field [0001] The invention relates to a mixed material, specifically a fiber-reinforced cement mixed material, which belongs to the field of building materials. Background technique [0002] The traditional cement mixture is based on cement clinker, and then supplemented with sand, fly ash and other materials. The existing cement mixtures are usually heavy in quality, which brings a lot of inconvenience to normal construction. It not only increases the construction dimension and strength, but also increases the cost of manufacturing and transportation, resulting in the consumption of a large amount of resources, which cannot adapt to economic and economic conditions. the needs of social development. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a fiber-reinforced cement mixture that is light in weight and convenient for transportation and construction.
