摘要

The contents of calcium sulphoaluminate (C_4A_3S) mineral were set as a series 5-20 percent and accordingly fixed tricalcium silicate (C_3S) mineral contents at 30, 45, 60 percent respectively in alite-sulphoaluminate cement clinker. The burning and properties of clinker were investigated. Results showed that: For certain C_3S content, the clinker sintering is loose when the content of C_4A_3S mineral is 5%, and the free lime amount is low, the cement setting time is long, the early age compressive strength is low, and a significant increase in the 28 days compressive strength is observed. When the contents of C_4A_3S mineral are 10% and 15%, the free lime amount is low, the clinker sintering compacter, the main mineral formation are good, and the cements show proper setting time and high compressive strengths. When C_4A_3S mineral content is 20%, the free lime amounts are high, the setting time of the cements is shorter, the early age compressive strengths are higher, while the compressive strength growth are smaller.
