Tricalcium silicate Dicalcium silicate Calcium sulfate dihydrate Tetracalcium aluminoferrite 2. The weight percentage of Tricalcium silicate in OPC is nearly 50% 25% 30% 5% 3. Most of the heat liberated during Hydration of Portland Cement is contributed by Tricalcium silicate Tricalcium aluminate Tetracalcium aluminoferrite Dicalcium silicate 4. Early strength of OPC is contributed by Tricalcium silicate Tricalcium aluminate Tetracalcium aluminoferrite Dicalcium silicate 5. Final strength of OPC is contributed by Tricalcium silicate Tricalcium aluminate Tetracalcium aluminoferrite Dicalcium silicate 6. "Finely ground cements will hydrate more rapidly, but they give rise to higher rates of heat liberation during hydration." True False 7. Gypsum is added to cement in-order to prolong hydration increase strength after hydration decrease heat of hydration reduce curing time 8. The role of the pozzolan in Portland Pozzolan Cements are to react slowly with the calcium hydroxide that is liberated during cement hydration reduce the heat of hydration increase resistant to sulfate attack All of the above 9. Expansive cements were developed to prevent severe cracking may occur as a result of the shrinkage. True False 10. Which of the following cement type is used in High-Temperature applications? Expansive Cements High-Alumina Cement Portland Blast-Furnace Slag Cements Portland Pozzolan Cements Be sure to click Submit Quiz to see your results!Please enter your mail id to get the correct answers on your mail.
