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.

Both weathered chert and sound quartz pieces are common constituents in stream gravels. Both have the chemical formula SiO2. Yet the weathered chert is an unsound material in concrete when subjected to freezing and thawing cycles, whereas quartz does not have this problem. Explain why this is the case.
The width of the expansion joint is 20mm in a cement concrete pavement. The laying temperature is 20 °C and the maximum slab temperature in summer is 60 °C. The coefficient of thermal expansion of concrete is 10 x 10-6 mm/ mm / °C and the joint filler compresses upto 50% of the thickness. The spacing between expansion joints should be
