Improved concrete compression-resistant modifier

Abstract

The invention discloses an improved concrete compression-resistant modifier, which is made by the following raw materials in parts by weight: 2.5-7.4 parts of slag powder, 2.5-3.3 parts of sodium carbonate, 1.5-3.7 parts of ferric oxide, 2.3-3.5 parts of cetyl trimethyl ammonium bromide, 0.8-3.5 parts of polyvinyl alcohol, 1.5-2.9 parts of phenyl salicylate, 3.3-5.8 parts of propyl p-hydroxybenzoate and 0.8-2.4 parts of guanidine hydrochloride. The possibility in capturing air by the concrete is reduced, and the stability of the concrete is improved. The concrete is continuously stirred up to keep the suspended state of solid components in the concrete slurry, and the phenyl salicylate, the propyl p-hydroxybenzoate and the guanidine hydrochloride are added to reduce the possibility in mixing the air in the concrete and prevent foam from being easily generated. After the concrete sets, the internal structure of the concrete is stable without clearances, the compression-resistant performance of the concrete is improved, the service life of the concrete is prolonged, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to an improved cement anti-compression modifier, which belongs to the field of building materials. Background technique [0002] Cement slurries have been widely used for a variety of purposes for a long time. When using cement slurries to construct stable rigid substrates, buildings and parking structures, it is critical to reduce the amount of air trapped in the hardened cement. The trapped air will reduce the stability of the hardened cement. However, cement slurries tend to foam due to the necessity of continuous stirring to keep the solid components in the cement slurries in suspension and also due to additives such as cellulose ethers added to the cement slurries. Thus, there is a strong need for a new type of cement slurry in which the foam formed can disappear quickly. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the technical problem to be solved by the present invention is to prov...
