75mm is the maximum clear cover of concrete
POUR THE CONCRETE OVER THE BRICK
A yard of Concrete is 3ft x 3ft x 3ft volume. It is usually poured over a 2" gravel sand mix for an additional four inches. So it should cover 36 "/4" = 9 (x 3ft x 3ft), or 81sq ft.The 'square feet' of area that it covers is 324/(depth of the concrete, in inches)
it is the clear cover for stirrups. effective cover of the reinforcement = nominal cover+ diameter of stirrups+half diameter of main bars
25 mm cover should be given
54sqare feet
75mm is the maximum clear cover of concrete
8.25 cubic yards of concrete
Depends on the area each concrete block can cover. The equation is: 150 sq ft / [area of each concrete block] sq ft = number of tiles. But in real life, it also depends on how tall and wide the 150 sq ft is, and how tall and wide the tiles are.
If it is the same as concrete it will cover 162 square feet. concrete covers 81 square feet by 4" deep

about 17 yards of concrete (it's sold by the cubic yard)
POUR THE CONCRETE OVER THE BRICK
the answer is 5kg the answer is 5kg
Given that the area of a rectangle is represented as A=l x w, where l =length, and w=width, and that a square is just a rectangle where all the sides are the same, the area of this square would = 2 feet x 2 feet. That yields a prodcut of 4 square feet, which is the area you would need to cover in poured concrete.
A yard of concrete is a cubic yard and cannot be converted directly to square feet of coverage. You must first determine the depth or thickness that the concrete will be. For instance, since 1 cubic yard equals 27 cubic feet, a 1 foot thick layer of concrete will cover 9 square yards of area. A 4 inch (1/3 foot) thick layer would cover 27 square feet of area.
An 80lb bag of concrete you can at your local home improvement store covers about 4 square foot at 2" thick. So you would need about 144 bags of 80lb concrete.
