Calcium silicate-based cements: composition, properties, and

WebbThe M3 polymorph is not found in pure tricalcium silicate. In industrial clinkers, the M1 and M3 polymorphs are mostly stabilised at room temperature by the presence of sulfate or magnesium impurities respectively (Maki and Goto 1982): these clinkers will be hereafter referred to as M1-type and M3-type clinkers. WebbThe presence of tricalcium silicate in cement a- hydrates the cement rapidly b- generates less heat of hydration c- offers high resistance to sulphate attack d- all of these 5. An excess of flaky particles in concrete aggregates a- Decreases the workability b- Increases the quantity of water and sand c- All the above.
