Question

What is the minimum to maximum water to cement ratio for a concrete mix?

1) .40 to .60
2) .40 to .50
3) .50 to .60
4) .50 to .40

Answer 1

The correct water to cement ratio for a concrete mix typically ranges from 0.40 to 0.60, ensuring the proper balance between workability and strength.

Step-by-step explanation:

The minimum to maximum water to cement ratio for a concrete mix generally varies but can be around 0.40 to 0.60. This means option 1) is correct. A lower ratio leads to higher strength and durability, but may be harder to work with. A higher ratio can be easier to work with but can reduce strength and durability.

Specific ratios depend on the requirements of the mix and its intended use. It is always important to follow established guidelines and standards for mixing concrete to ensure the safety and structural integrity of construction projects.
