Initial Set
Final Set
False Set
True Set
The time required for the paste to harden to a certain degree. The time required for the gauged cement to acquire sufficient firmness to resist a certain definite pressure.
Initial Set
Final Set
False Set
True Set
This method of test is for determining the soundness of Portland cement, soundness is a physical property tested by determining the ability of a hardened cement paste to retain its volume after setting.
