In placing concrete under water using Tremie method -------method is followed for less flowable concrete

In hydro valve method , ---------- & ---------are the resistive forces that is suddenly overcame by concrete weight

The ----------method of underwater concreting is suitable for cases where a large mass of concrete is required for stabilizing foundations and small amount of concrete is needed for different locations.

Concrete placed at an atmospheric temperature------- degree centigrade is considered as hot weather concreting

--------- is not an effect of hot weather concreting

------ is not a step to control defects in mass concrete

Water reducing admixtures are generally called by the name -----------

----- is not an effect of cold weather concreting

The ---------- underwater concreting is suitable for cases where a large mass of concrete is required for stabilizing foundations and small amount of concrete is needed for different locations.

------is not a method adopted for concreting in cold weather

Post cooling can be made by insulating concrete as soon as concreting is done in mass concrete. State whether the statement is true or false

----------are useful in cases where it is not possible to achieve full concrete cover on the reinforcement, or in repair situations.

The admixture that increases the cohesion of the cement paste without reduction of the workability and prevents washout of cement grout

-------------is used to pre cool materials for Mass concrete
