Which of the following options matches the parameters and the values correctly?

Workability of concrete can be measured using slump, compaction factor and Vee bee time. Consider the following statements for workability of concrete:

(i) As the slump increases, the Vebe time increases

(ii) As the slum increases, the compaction factor increases

Which of the following is TRUE?

Consider the following statements for air-entrained concrete:

(i) Air-entrainment reduces the water demand for a given level of workability

(ii) Use of air-entrained concrete is required in environments where cyclic freezing and thawing is expected.

Which of the following is TRUE?

The composition of an air-entrained concrete is given below:

Water : 184 kg /m³

Ordinary Portland Cement(OPC) : 368 kg /m³

Sand : 606 kg /m³

Coarse aggregate : 1155 kg /m³

Assume the specific gravity of OPC, sand and coarse aggregate to be 3.14, 2.67 and 2.74, respectively. The air content is_________ liters/m³
