In respect to this, and only as a rough guide, the ratio of water to cement should be around 0.55. If your total cement requirements were 25kg, then the calculation would be: 25 x 0.55 = 13.75kg (litres) of water. Water in litres = Total volume of cement required x 0.55.
As per BS 8500-2 British/European standards, the grade of concrete is denoted as C10, C15, C20, C25, etc., 'C' which means 'Concrete Strength class', and the number behind C refers to characteristic Compressive strength of Concrete in N/mm2 @ 28 days when tested with the 15 cm dia. & 30 cm height cylinder in a direct compression test.

Also, red mud could be used as an aggregate in common application concretes, where red mud content could be 15 … 40% by mass (350 … 900 kg/m 3) for concrete classes C15 … C40. For pressed materials red mud content could reach 90% by mass of the material, meeting the specified requirements for road base.
WebNominal mixes for grades of concrete such as M15, M20, M25 are generally used for small scale construction. Large structures have high strength requirements, thus they go for higher grades of concrete such as M30 …
It was observed in Fig. 9 that both size and quantity of the tire rubber in the concretes had marked effects on the characteristic length in the positive way. Indeed, plain concrete had characteristic length of 324.5 mm which increased to almost 600 mm at the concretes with 5% tire rubber, irrespective of the size. From 5% to 25% replacement ...

The GCR–GFA-C05, GCR–GFA-C10, GCR–GFA-C15, and GCR–GFA-C20 concretes showed the highest temperature rises of 14, 15, 17, and 18 °C, respectively, after mixing for 22–24 h. The peak temperature rise of the GCR–GFA concretes containing Portland cement was still much lower than that of the OPC concrete.

In 1944, Tremper 5 in the United States performed the pull-out test on concretes of different ages, different water-to-binder ratios, and different coarse aggregates. Through a regression analysis, the correlation between the pull-out force and concrete compressive strength was obtained. The experiment showed great improvement over the …
However, the increase in compressive strength is not necessarily required in most applications (Pelisser et al., 2018). Also, these concretes always have high cement consumption. The methodology proposed in this study was successful in the reverse direction, and included concretes with reduced cement consumptions and low …
Compacted sand can generally be used as a blinding layer for the application of pavements. It is rarely used as a blinding layer beneath footings as the stress concentration for these applications is usually too high. If compacted sand is used as a blinding layer for pavements it is generally adopted in conjunction with a damp proof membrane.

For M 15 grade of concrete mix, the ratio is 1:2:4, which means 1 part cement, 2 part sand, and 4 part aggregate used to prepare concrete mix with water. If you are using M 20 grade of concrete then you have to use a mix ratio of 1:1.5:3. In which 1 is part of cement, 1.5 is part of sand, and 3 is part of cement. Grade of Concrete.
