**1)what is concrete and its types and properties**

You are preparing a ready mix concrete for casting of slab which shall be at 3″, 4″, 5″, 6″, 8″, 10″ & 12″ thick then what will be their weight per sq ft & how do you calculate concrete quantity.

Cured concrete generally weigh around 4050 pounds per cubic yard or 150 pounds per cubic foot which is approximately equal as 2400kg/m3 in metric system. In United States volume of concrete measured in yard (short form of cubic yard) and their weight measured in pounds (lbs).

When we poured fresh concrete for your slab, it will take 24 hours for initial setting, after this curing of concrete is required, curing practices involves keeping the concrete damp or moist until the hydration of concrete is completed and strength is attained. The curing increases the strength and reducing permeability of concrete.

**How much does a square feet (sq ft) of concrete weigh?**

Weight of concrete is calculated by multiplying volume and their density and volume is multiplication of their square footage and thickness of slab. Weight of concrete per square feet is calculated by dividing by their thickness.

Generally 1 cubic foot of cured concrete weigh around 150 pounds, divide this weight by thickness of concrete in feet to get weight of concrete per square foot such as with a standard thickness of 4 inches, normal weight concrete weighs approximately 50 lbs per square foot (4″ = 0.33 feet, 0.33 × 150 = 50 lb).

Regarding this, “**how much does a square feet (sq ft) of concrete weigh?”**, with a standard thickness of 1.5 inches, normal weight concrete weighs about 19 lbs per square foot, for 2 inch deep it will be weigh around 25 lb/ sq ft, for 3 inch deep – 38lb, for 4 inch deep – 50lb, for 5 inch deep – 62lb, for 6 inch deep – 75lb, for 8 inch deep – 100lb, for 10 inch deep – 125lb and for 12 inch deep concrete will weigh about 150 pounds per sq ft.

**How do you calculate concrete**

**You can calculate concrete in following steps:-**

● Determine how thick you want the concrete and measure the length and width that you’d like to cover

● Multiply the length by the width to determine square footage of concrete

● Convert the thickness from inches to feet by dividing with 12

● Multiply the thickness in feet by the square footage to figure out cubic feet

● Convert cubic feet to cubic yards by multiplying by .037

For example consider a concrete patio 10 feet by 10 feet of standard 4 inch thick, then calculate concrete quantity in cubic yard by following ways:-

● Multiply the length by the width to determine square footage of concrete such as 10′ × 10′ = 100 sq ft

● Convert the thickness from inches to feet by dividing with 12 such as 4÷12 = 0.33 फीट

● Multiply the thickness in feet by the square footage to figure out cubic feet such as = 100 sq ft × 0.33 feet = 33 cubic feet

● Convert cubic feet to cubic yards by multiplying by .037 such as 33 × 0.037 = 1.221 cubic yards.
