PH value is not applicable to weather as it is a measure of acidity or alkalinity of a solution.

• PH value is a measure of the concentration of hydrogen ions in a solution.

• It is used to determine the acidity or alkalinity of a solution on a scale of 0 to 14.

• Weather does not have a PH value as it is not a solution.

• However, PH value can be affected by weather conditions such as acid rain.

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

• It is an important factor in determining the strength and durability of concrete.

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

• The ideal water cement ratio varies depending on the type of concrete and its intended use.

• For example, a water cement ratio of 0.45 is recommended for concrete used ...read more
