Workability of a concrete mix with low water cement ratio is determined by (a) tensile strength test (b) water content test (c) cube compression test (d) compaction factor test
Answers
Tensile,
The aim of tensile test is to determine certain material properties like Modulus of Elasticity, Yield Strength, Ultimate Tensile Strength, Elongation till fracture, and Reduction in area of the specimen after it has been deformed.
Water Content,
Aim of the test:
Aim of the test:To sight a few, natural moisture content is used in determining the bearing capacity and settlement. The natural moisture content will give an idea of the state of soil in the field.
CubeCompression test
The compacting factor test is designed primarily for use in the laboratory but it can also be used in the field. It is more precise and sensitive than the slump test and is particularly useful for concrete mixes of very low workability and normally used when concrete is to be compacted by vibration.
...There fore option C is the correct
