The durability of concrete is proportional to
ANSWER= [D] Cement aggregate ratio
Explain:- Correct answer for the question Durability of concrete is proportional to (the durability of concrete is proportional to) is [D] Cement aggregate ratio
Water/Cement (W/C) ratio decides the workability and compressive strength of the concrete also. The higher the water/cement ratio means higher the workability of concrete and the lower will be its compressive strength.
Sand content help to decides the bulkiness of concrete prepared and also control the cement content quantity in concrete. Higher sand content means more bulky is concrete.
Aggregate ratio i.e. ratio of coarse aggregate to fine aggregates decides the volume of air voids in concrete and degree of gradation (whether the sample is well graded or poorly graded) of concrete sample.
Cement/Aggregate ratio decides the durability of concrete and also workability of concrete owing to volume changes due to differences in thermal properties of the aggregates and cement paste.
Some Other factors also affecting the durability of concrete are:
- Cement Content
- Concrete Compaction
- Curing Period
- Temperature
- Alkali-Aggregate Reaction
- Sulphate Attack
