• C. Dura cement
• D. Low Heat Cement

Answer 1

Answer: (A)

Portland Cement

Portland cement is the most commonly used cement for construction purposes. It is made from 25% silica, 60% lime and 5% alumina, apart from iron and gypsum.
High alumina cement is used for the construction of refractories, foundries and other workshops where high temperature is required. Dura cement is used in mass concreting work where environmental conditions are not so suitable for use of normal cement. Low heat cement is also used in mass construction work.
