Abstract

The invention discloses a high-performance composite cement grinding aid and a preparation method thereof. The high-performance composite cement grinding aid is made from, by weight, 10-15 parts of triethanolamine, 2-5 parts of glycerol, 1-3 parts of sodium thiocyanate, 5-8 parts of diethylene glycol, 10-13 parts of sodium acetate and 56-77 parts of water. The high-performance composite cement grinding aid and the preparation method thereof have the advantages that the range of origin is wider for the materials, the preparation method is simple, the finished product made by compositing the materials can enhance cement strength and increase cement production efficiency and can also reduce strength developing change differences between composite cement and pure-silicon cement, durability andworking performance of concrete are changed, production cost is reduced, emission of carbon dioxide is reduced, and the high-performance composite cement grinding aid has a good application prospect.

Description

technical field [0001] The invention relates to the field of cement grinding aids, in particular to a high-performance composite cement grinding aid. Background technique [0002] The construction industry is an industry that revolves around the design, construction, decoration, and management of buildings. Urban architecture is an important part of the construction industry. Urban architecture inherits culture in its unique way, spreads the charm of life, and continuously penetrates into the In people's daily life, create a harmonious and peaceful spiritual home for people. [0003] Building materials are a general term for materials used in urban construction. Building materials can be divided into structural materials, decorative materials and some special materials. Cement is a common building material. [0004] Cement is a powdery hydraulic inorganic gelling material. After adding water and stirring, it becomes a slurry, which can be hardened in the air or better har...
