Which of the following is correct for Low Heat Cement Heat of hydration is reduced by tricalcium aluminate content Suitable for use in cold weather areas Suitable for use in Hot weather areas This cement requires longer period of curing Hydration of cement is due to chemical action of water with * Tetra calcium Aluminoferrite Tricalcium silicate and Dicalcium silicate Tricalcium aluminate and Tricalcium alumino ferrite Gypsum
In the solution with the same concentration, strength loss of the hardened cement paste soaked in magnesium sulfate solution was less than that in sodium sulfate solution. why?
Reinforced concretes are usually attacked by water and rusted. This is due to, a. Low density cements or high porosity that allow water to reach the steel b. The expansion of the rust as it has higher volume than steel push the cement cover and break it c. All the options d. None of the options e. The cover thickness is too small (the steel is too close to the end of the concrete block)

Hydration of cement is exothermic process that generates heat. The table below shows the heat generate with different cement components. Which component is recommended to build a dam wall which is a large amount of cement block? a. None of the above b. C2S only which generate less heat and less thermal stress c. A mixture of Low heat cements to avoid thermal stress and high energy released and other factors should be considered. d. C3A because it generates large amount of heat and dry the block faster.
