Multi-effect concrete water reducer

Abstract

A multi-effect concrete water reducer is prepared from raw materials in parts by weight as follows: 3-8 parts of modified straw ash, 5-7 parts of polyethylene wax, 3-6 parts of urea, 1-4 parts of sugar calcium, 7-11 parts of animal hair hydrolysate, 5-10 parts of metolachlor, 6-8 parts of bentonite, 3-8 parts of eucalyptus oil, 5-8 parts of fulvic acid potassium, 8-13 parts of melamine, 4-9 parts of alcohol ethoxylate, 6-9 parts of phenol, 2-8 parts of sodium chloride, 5-9 parts of sodium sulfate and 7-9 parts of calcium chloride. The multi-effect concrete water reducer has the benefits as follows: the water reducing effect is enhanced, the frost resistance and strength of concrete are improved simultaneously, and the concrete water reducer has a delayed coagulation effect.

Description

technical field [0001] The invention relates to a multi-effect concrete water reducer. Background technique [0002] Water reducing agent refers to the admixture that can reduce the mixing water consumption and improve the concrete strength under the condition of constant workability and cement dosage of concrete; or save the dosage of cement under the condition of constant workability and strength. The requirements for high-efficiency water-reducing agents for the construction of high-performance concrete are also strict. Both the water-reducing rate of the water-reducing agent and the air-entraining components of the water-reducing agent will affect the quality of high-performance concrete. The existing water reducing agents have the disadvantages of single performance, poor adaptability and unsatisfactory water retention effect. High-efficiency water reducers have always been a direction of research. Contents of the invention [0003] Aiming at the deficiencies of the...
