36.
Pick up the incorrect statemnt from the following. For performing compressive strength test of cement
cement and standard sand mortar are used in the ratio of 1 : 3
water is added at the rate of 
+ 3.0 percentage of water where P is the percentage of water for standard consistency
+ 3.0 percentage of water where P is the percentage of water for standard consistencyA cube mould of 10 cm x 10 cm x 10 cm is used
The perpared moulds are kept in a atmosphere of 90% relative humidity
The temperature of water in the submerged tank for curing moulds, should be 27° ± 2°C.
