Water cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix.

• Water cement ratio is a crucial factor in determining the strength and durability of concrete.

• A lower water cement ratio results in stronger and more durable concrete.

• Typical water cement ratios range from 0.4 to 0.6 for normal strength concrete.

• For high strength concrete, water cement ratios can be as low as 0.25.

Quality is the measure of excellence or superiority of a product or service.

• Quality is meeting or exceeding customer expectations.
