Hence, to prepare 1 cubic meter of M20, M15 and M10 concrete, 1.57 cubic meters of "total dry volume" of cement, sand and aggregate are needed, whereas to prepare 1 cubic meter of M7.5 and M5 concrete, 1.52 cubic meters of "total dry volume" of cement, sand and aggregate are needed. Many websites are giving different values for the "total dry volume" of the ingredients.

Strength of PCC is defined as compressive strength after 28 days, expressed as M15, M20, where M stands for Mix and 15 stands for 15 N/mm 2 (n/mm 2 must be read as 'Newton's per millimeter Cubic') compressive strength at 28 days. The proportions of materials (cement, sand, coarse aggregate) for nominal mix/design mix concrete that are normally used are 1:3:6 or 1:4:8.

Concrete Mix Ratio Using Ballast. For typical domestic use, 1 cubic metre of concrete at 3500 psi (25 MPa) can be readily created by mixing seven 50 kg bags of cement with 0.7 cubic metres of sand and 0.7 cubic metres of stone aggregate. Concrete of this strength is ideal for patio slabs, footpaths and steps. By increasing the cement:aggregate ...

Rounded off it's basically a : 1 : 3 : 2.5 mix ratio. If I break the weights down per cubic yard of concrete it comes to: 1. Cement = 553 pounds. 2. Stone = 1630 pounds. 3. Sand = 1470 pounds. There are 94 pounds of cement in a "sack or bag" of cement. That means 3500 psi concrete is called a 6 sack mix or 6 bag mix of concrete.

The mixes of grades M10, M15, M20 and M25 correspond approximately to the mix proportions (1:3:6), (1:2:4), (1:1.5:3) and (1:1:2) respectively. Designed Mix Ratio of Concrete In these mixes the performance of the concrete is specified by the designer but the mix proportions are determined by the producer of concrete, except that the minimum ...

The density of concrete is 3.15 g/cm 3 while the density of aggregate will vary by the type of stone used. For instance, gravel has a much higher density than vermiculite. The density of a typical concrete mix is 2.4 g/cm 3 or 150 lbs/ft 3. Different mixes of concrete will use more or less aggregate as well.

This standard concrete mix (used for most premix applications) weighs about 133 pounds per cubic foot of concrete, so a cubic yard (which contains 27 cubic feet) will weigh in at about 3,600 pounds. With the given mix ratio, cured concrete is about 22 percent cement by weight.
