All the mentioned tests (slump test, flow test, and Kelly ball test) are used to measure the workability of concrete.

Question 10

&#34;Membrane curing required more water compare to water curing&#34;, is it true or false?&#10;A)true&#10;B)false&#10;C)none&#10;D)all

Accepted Answer

Membrane curing does not require more water compared to water curing. In membrane curing, a membrane-forming compound is applied to the surface of the concrete to reduce the loss of water, whereas water curing involves continuously wetting the surface of the concrete with water to ensure proper hydration of the cement.
