Concrete Technology - Section 1 (3)

The process of proper and accurate measurement of concrete ingredients for uniformity of proportion, is known

For the construction of cement concrete floor, the maximum permissible size of aggregate, is

Curing a concrete for long period ensures better

If 20 kg of coarse aggregate is sieved through 80 mm, 40 mm, 20 mm, 10 mm, 4.75 mm, 2.36 mm, 1.18 mm, 600 micron, 300 micron and 150 micron standard sieves and the weights retained are 0 kg, 2 kg, 8 kg, 6 kg, 4 kg respectively, the fineness modulus of the aggregate, is

The commonly used material in the manufacture of cement is

Workability improved by adding

To ensure constant moisture content in aggregates

The ratio of the length to breadth of a wooden float, is
