Chemical additive used for calcium sulphoaluminate-modified Portland cement
The present invention discloses a chemical additive used for calcium sulphoaluminate-modified Portland cement, the chemical additive includes the following matters: (a) at least one alkanolamine borate; (b) at least one organic alcohol; and (c) at least one saccharide or a derivative thereof; and the matters and water are sequentially mixed and stirred to obtain the chemical additive used for calcium sulphoaluminate-modified Portland cement. The chemical additive used for calcium sulphoaluminate-modified Portland cement has better effects of regulation of calcium sulphoaluminate-modified Portland cement setting time and improvement of 3d / 28 strength increase rate, and also has grinding aid effect during grinding process.
