1.54 is a factor that helps us to convert the Wet Volume of Concrete into Dry Volume. So that we can calculate the number of materials in dry condition. 1.54 is nothing but a 54 percent increment of Wet volume of concrete along with Wet Volume.

Besides, What is meant by dry volume of concrete?

1) dry volume means volume of ingredient of concrete like sand cement and aggregate in mix dry condition before adding water. Wet volume means volume of ingredient of concrete like sand cement and aggregate in wet mix after adding water. 2) dry volume of concrete is approx 54% is more than wet volume of concrete.

Keeping this in mind, Why is 1.54 dry volume? From there we obtain wet volume of concrete. So to calculate quantity of raw material we need to convert wet volume to dry volume. So , 1.54 is conversion factor of wet volume to dry volume of concrete.

1. Total Cost. = Builtup area × Approx cost per sq. ft. = 1000 × 1000. = 1000000.00 Rs. …
2. Amount of Aggregate Required. = Builtup area × 0.608. = 1000 × 0.608. = 608.00 Ton. …
3. Flooring. = Builtup area × 1.3. = 1000 × 1.3. = 1300.00 Sq.

## How do you dry concrete?

How Concrete Dries. Concrete dries as the water inside it evaporates through its surface. As this water evaporates through the surface, water from deep within the concrete moves through the capillaries and up to the surface to replace it. As long as the surrounding air can hold more water vapor, evaporation continues.

## How can you tell if concrete is dry?

24 to 48 hours – after inital set, forms can be removed and people can walk on the surface. 7 days – after partial curing, traffic from vehicles and equipment is okay. 28 days – at this point, the concrete should be fully cured.

## How long does concrete take to dry?

Concrete typically takes 24 to 48 hours to dry enough for you to walk or drive on it. However, concrete drying is a continuous and fluid event, and usually reaches its full effective strength after about 28 days.
