High-effective concrete compound additive and its production method

Abstract

The composition of high-efficiency composite additive for concrete is formed from (wt%) triethanolamine 10-50, sodium metnylene bis-naphthalene sulfonate 20-50, bone glue 4-8, tartaric acid 10-20, rosin 3-6, stearic and 8-10 and water 105-210. Said invention is low in cost, small in addition quantity, easy to transport and store and convenient for operation and construction, and said additive can resist the corrosion action of preembedded metal, can improve plasticity and workability of concrete, can greatly reduce water gain and segregation and can make poured concrete more homogeneous and compact, etc.

Description

Technical field: [0001] The invention relates to a concrete admixture and a production method thereof, in particular to a high-efficiency concrete composite admixture and a production method thereof. Background technique: [0002] As we all know, mixing some effective component additives in concrete can effectively improve the quality and performance of cement products. As early as the 1930s, the United States widely used air-entraining admixtures in road construction to improve concrete construction. In recent years, through a large number of scientific experiments, people have continuously improved concrete admixtures and developed concrete admixtures with different properties, such as early strength agents, water reducing agents, and film release agents. , antifreeze, waterproof leak-proof agent, curing agent, etc., the existing concrete admixtures have the following defects: first, the function is single, and the overall performance is poor; second, the dosage is large, ...

[0002] As we all know, mixing some effective component additives in concrete can effectively improve the quality and performance of cement products. As early as the 1930s, the United States widely used air-entraining admixtures in road construction to improve concrete construction. In recent years, through a large number of scientific experiments, people have continuously improved concrete admixtures and developed concrete admixtures with different properties, such as early strength agents, water reducing agents, and film release agents. , antifreeze, waterproof leak-proof agent, curing agent, etc., the existing concrete admixtures have the following defects: first, the function is single, and the overall performance is poor; second, the dosage is large, mostly in a few thousandths, and some even as high as a percent The number of times brings difficulties to transportation and storage. At the same time, it is difficult to mix during construction, and the work efficiency is low. Third, the cost is relatively high.
