To calculate the quantity of cement, sand, and aggregates required for a flat slab, first we need to calculate the volume. Area of flat slab = 1000 sq.ft =93 sq. m. The minimum thickness provided for the slab is 150 mm. ( According to IS 456) 150 mm = 0.15 metres. Hence Wet volume = Area of slab x Thickness of slab.

Example for concrete calculator in Yards, Here, I want to show you a calculation for a 20' by 20' and 3'' thickness concrete slab. 1 . 20×20 = 400 square feet. 2 . 3/12 = 0.25 feet. 3 . 400x 0.25 = 100 cubic feet. 4 . 100 x 0.037 = 3.7 cubic yards. The above example is solving for volume in yards.
Many builders and gardeners are faced with calculating or estimating the amount of sand they need to fill a given space with sand. Our sand calculatoris of great utility in such cases, but you should keep in mind that the results will only be as good as the measurements entered. The … See more

From the table in the previous section of this text, we need a mix ratio of 1:5:10 to make a 5.0 MPa (725 psi) concrete block. By adding the ratio's parts together, we obtain the total parts to be 1 + 5 + 10 = 16. Among these 16 parts, cement is one part of it, sand is another 5 parts of it, and gravel is the remaining 10 parts.
It may not seem like much, but by combining one part water with 99 parts dry sand, you are giving yourself the best chance of building the perfect, most stable sandcastle. The team concluded that 'if this optimum concentration is used, sandcastles reaching five metres in height can be built.'. That would certainly be enough to impress any kids.
material such as sand, gravel, crushed stone, blast-furnace slag, and lightweight aggregates that usually occupies approxi-mately 60 to 75% of the volume of concrete. Aggregate properties significantly affect the workability of plastic concrete and also the durability, strength, thermal properties, and density of hardened concrete.
Mixer calibration should be completed on a frequency that makes sense for the foundry's volume of work. This might mean calibrating once per shift or once per week. Mixer calibration checks should include measuring sand flow, sand additive level, binder flow, and catalyst flow. Changes in binder temperature can affect calibration levels, too.
