Abstract

The present invention discloses a special water reducing agent for machine-made sand. The special water reducing agent is prepared from the following raw materials: a, prenol polyoxyethylene ether, b, acrylic acid or methacrylic acid, c, allyltrimethylammonium chloride, d, ammonium persulfate, e, sodium hypophosphite, f, mercapto propionic acid or mercapto acetic acid, and g, sodium hydroxide, wherein a mol ratio of a to b to c to g is 1:2-3:0.2-0.3:1-2, the amount of the raw material d is 0.2-0.5% of the total amount of the raw material, the amount of the raw material e is 1-2% of the total amount of the raw material, and the amount of the raw material f is 0.1-0.3% of the total amount of the raw material. The present invention further discloses a synthesis method of the special water reducing agent. According to the present invention, the special water reducing agent product has characteristics of good adaptability to machine-made sand concrete and effective machine-made sand concrete quality improving, and has broad market prospects.

Description

technical field [0001] The invention relates to a water reducer, in particular to a special water reducer for machine-made sand and a synthesis method thereof. Background technique [0002] As the demand for concrete continues to rise, the supply of concrete material river sand is seriously insufficient. Many cities at home and abroad use machine-made sand instead of river sand. Concrete using machine-made sand generally has poor workability, poor fluidity, and poor compatibility with water reducing agents, which brings hidden dangers to the quality of concrete. Contents of the invention [0003] In view of the above shortcomings, the object of the present invention is to provide a special water reducer for machine-made sand, and also includes its synthesis method. [0004] The technical solution of the present invention is realized in the following way: a special water reducer for machine-made sand, made of the following raw materials: [0005] a. Isopentenol polyoxyeth...
