Screed concrete used on the floor consists of cement as a binder, water and sand that passed through a 4 mm sieve.
Simple screed concrete is made by adding 500 kg of cement to 1 m³ of sand.
One cubic meter of sand weighs on average 1500 kilograms and 1 cubic meter of concrete weighs approximately 2400 kilograms.
If we take the screed concrete mixture ratios as 1 kilo of cement, 3 kilos of sand and 1 kilo of water, it equals 5 units. Three-fifths of 1 cubic meter of concrete (2400 kilograms), that is, 1440 kilograms, is sand.
Let’s say 5 cm of screed concrete will be placed. The volume of 1 square meter surface screed with a thickness of 5 cm is 1/20 cubic meter. In this situation, 1440/20 = 72 kilos of sand is sufficient for 1 square meter screed with a thickness of 5 cm.
