If aggregates completely pass through a sieve of size 75 mm and are retained on sieve of size 60 mm, the particular aggr…

The 28 days cube strength of mass concrete using aggregates of maximum size 5 cm for gravity dams should be

The top diameter, bottom diameter and the height of a slump mould are:

A suitable admixture added at the time of preparing the concrete mix, makes the concrete

For finding compressive strength of concrete, the minimum number of cubes required is

The mixer, which produces a steady stream of concrete as long as it is in operation, is known as

The workability of concrete is defined as the

The size of fine aggregated does not exceed
