What can be done to minimize the thermal gradient in a mass concrete pour?

$q,$

Use micro silica Use set accelerators

Plasticizers are sometimes also referred to as "water reducers" because they act to reduce the water that has been added to the concrete to improve compressive strength.

True

False

Question $16($Mandatory$)$

When calculating the compressive strength of concrete, it is necessary to know:

rate of loading and date of specimen molding.

diameter of the speciment and final compressive load.

none of these.

source of aggregates and absorption of both coarse and fine aggregates.
