Compression-resistant cement modifier

Abstract

The invention discloses a compression-resistant cement modifier prepared from the following raw materials in parts by weight: 2.5-3.8 parts of gleditsia sinensis, 1.5-3.6 parts of calcium oxide, 2.5-5 parts of zeolite powder, 3-8 parts of modified soybean protein powder, 2.5-5 parts of methanol, 0.8-2.2 parts of gamma-trimethoxysilylpropanethiol, 1.5-3.6 parts of an aminosilane coupling agent and 3.5-6.8 parts of a bisphenol A epoxy resin aqueous emulsion. Compared with the existing cement modifier, the compression-resistant cement modifier is low in cost and capable of better solving the technical problems such as cement hardening, poor water resistance, small cementing power, no wear resistance and no frost resistance; and a great number of experiments prove that all the performances of Portland cement are greatly improved after the modifier disclosed by the invention is added into the Portland cement.

Description

Technical field [0001] The invention involves a cement anti -voltage modified agent, which is the field of building materials. Background technique [0002] At present, the cement used in the building is prone to hardened phenomenon, mainly due to calcium hydroxide, calcium silicate and hydration.Such cement is prone to cracking, which in turn leads to low strength and low toughness.In order to solve this problem, it is generally necessary to add a modified agent to such cement to improve the phenomenon of cement sclerosis.However, some ordinary cement also has defects such as poor waterproofing, small adhesion, abrasion resistance, and non -freezing.In order to solve these problems of ordinary cement, a variety of different modified agents, additives, etc. are needed. Although the performance of the cement is good, it greatly increases the cost of cement.Due to the different components of each additive, the components in different additives may also react, resulting in the pheno...
