You can also watch our video here: Video on concrete mix ratio of various grades of concrete. Designed Mix Ratio of Concrete. So, what really does M10 or M20 mean or represent. Water content = 180kg. Prescribed Concrete Mixes. For example, for M20 grade of concrete mix, its compressive strength after 28 days should be 20 N/mm2. type mixer in my factory CONCRETE MIX DESIGN (GRADE M60) (a) DESIGN STIPULATION:-Target strength = 60Mpa Max size of aggregate used = 12.5 mm Specific gravity of cement = 3.15 Specific gravity of fine aggregate (F.A) = 2.6 Specific gravity of Coarse aggregate (C.A) = 2.64 Dry â¦ As per Table No. The concrete mix ratio refers to the proportion of the components in the concrete. To make ease in understanding we are finding the Concrete mix design of M20 grade concrete. As we know that Foundation footing is RCC structure so we can use minimum grade of M20 grade and concrete mix ratio 1:1.5:3 for Foundation & maximum grade of concrete m25, M30 and much higher are used as per design for Foundation footing. we use M5, M7.5, M10, M15 grade concrete. We keep proportion of cement, sand and coarse aggregate fix in case of nominal mix design to gain to characteristics strength after 28 days. (As per contract Minimum cement content 400 kg / m3). Concrete respectively, and. “M” stands for “mix”. LEAN CONCRETE. "M" stands for Mix of the ratio of cement:sand:aggregate. Assume cement content 400 kg / m3 = 0.4: 1: 1.65: 2.92. The Concrete mix ratio for M20 grade of concrete is 1:1.5:3 that mean 1 part of cement, 1.5 part of sand (fine aggregate) and 3 parts of aggregate (crushed stone) in volume and then batched for mixing. Greater the amount of water, higher will be the workability of concrete (more fluid) however it reduces the strength of concrete. Coarse Aggregate (20mm) = 2.65 We all know that on mixing cement with sand, stone/aggregates and water, a paste will form which can be used to bind the building materials together. 1. Target Mean Strength = 40 + (5 X 1.65) = 48.25 Mpa. Hence, a balance has to be found in the construction site during concrete mixing. Vikram Singh yadav. M20 :1:1.5:3. 4, IS: 10262) The volumetric mix ratio of M20 concrete is 1:1.5:3, hence 1 part of cement, 1.5 part of sand and 3 part of aggregate in volume is needed to prepare M20 grade concrete. Lean concrete is a mix where the amount of cement is lower than the amount of liquid present in the strata. (ca/Sca) ] x (1/1000). This concrete mixture ratio of 1 part cement, 1 parts sand, and 3 parts aggregate will produce a concrete mix of approximately 2500 to 3000 psi.
