Method for preparing chemical admixtures for alkali activated slag concrete and chemical admixtures manufacture by the same
The present invention relates to a method for making a chemical admixture for alkali-activated slag concrete, which comprises a step for mixing an oil-type polycarboxylic acid-based raw material synthesized by using di-acrylate and a dispersed polycarboxylic acid-based raw material having the pH of 6.0 or more with weight ratio of (40 to 60):(60 to 40) to make a raw solution (S10). Accordingly, the present invention aims to provide the chemical admixture, which can continuously exhibit fluidity and a water reducing effect due to properties of a polycarboxylic acid system even under a strong alkaline environment, thereby improving the workability and moldability.
