Resistant to weak acids and especially sulfates, this cement cures slowly and has very low durability and strength.(a) True(b) FalseThe question was asked in an interview for job.I need to ask this question from R.C.C.

Answer» Right option is (b) False The best explanation: Resistant to weak acids and especially sulfates, this cement cures quickly and has very high durability and strength. It was frequently used after World War II to MAKE precast concrete objects. However, it can lose strength with HEAT or time (conversion), especially when not properly cured. After the collapse of three ROOFS made of prestressed concrete beams using high alumina cement, this cement was BANNED in the UK in 1976. Subsequent inquiries into the matter showed that the beams were improperly manufactured, but the ban remained.
