Concrete mix ratio is a vital topic in concrete mix design. The four basic ingredients for making concrete are: Portland cement, sand, aggregate (stone) and water. The strength of concrete mixture depends on the ratio in which these four ingredients are mixed.

Concrete mix design is the process of detrmining right proportions of cement, sand and aggregates for concrete to achieve target strength of concrete. For concrete mix design, we have to perform many laboratory testing and calculations to find right mix proportions.

2. Nominal mix concrete may suggest more cement than other materials, and concrete mix designs gives the accurate quantity of cement consumption. Thus it is an economical solution for large projects. It is possible to save up to 15% of cement for M20 grade of concrete with the help of concrete mix design. In fact higher the grade of concrete ...

Mar 27, 2017· In IS:, the different grades of concrete are given as M10, M25, M20, M25, M30, M35, and M40. In the classification of concrete mix, the letter M denotes the Mix and the numbers 10, 15, 20, 25, 30, 35, 40 represent the predetermined works cube .

Roller compacted concrete is a zeroslump concrete, low water content, dense mix consisting of coarse aggregate, sand, cementitious materials, and water. By using conventional vibrators, it is very difficult to compact for larger thicknesses. There is a chance of getting honey combing and inconsistency with respect to laboratory values.

Fine Aggregate : Mix of River Sand and and Robo sand. Concrete : Design Mix M20 (As designed by reputed Institutions) Reinforcement Steel : Fe 500 ...

The lower the w/c ratio, the higher the concrete strength. All materials used for a design including the water quality should be to a high standard. A general rule of thumb is, if the water is palatable then it is suitable for mixing concrete.

The scope ... codes are summarised by illustrating the design steps. A typical M20 mix design is presented using these methods. Dr Deepa, (2014) [4] The ...

The strength of the concrete is termed by grade. The grade reflects the compressive strength which is the characteristic strength of concrete after 28 days. It is depicted by a letter M followed by a number. For instance, if the grade of the concrete is said to be M20, it means that the concrete mix (M) has a compressive strength of 20 N/mm2.
