The Minimum grade of concrete for Reinforced Cement Concrete (RCC) is M20 Concrete Grade and Mix Ratio Table As per IS 456:2000, the grades less than M20 should not be used in RCC works 2.1. b) The applicability ofthe standard has been specified for ordinary and standard concrete grades only. Water quantity is depends upon the climatic factors and workability required. Actual site conditions vary and thus this should be adjusted as per the location and other factors. Concrete Mix Design Calculation : M20, M25, M30, M40 Grade Concrete Concrete mix design is a procedure of selecting the suitable ingredients of concrete and their relative proportions with an objective to prepare concrete of certain minimum strength, desired workability and durability as economically (value engineered) as possible. 0000001166 00000 n Hence we require 8 bags of cement for 1m3 of concrete. hiiii buddy….. Add 3 gallons of Super Plasticizer to the mix and you will get 7- to 8-in slump concrete without any water added. Scope. 429 18 For 1m3 of Concrete = 403.2Kgs of Cement is required. of bags required for 1 cum of cement. To make ease in understanding we are finding the Concrete mix design of M20 grade concrete. You can use same method to calculate any grade of concrete. 0000002123 00000 n It increases the volume of sand (bulking of sand). As per IS456:2000, Different grades of concrete are classified into M5, M7.5, M10, M15 etc., whereas M stands for Mix and the number behind M stands for Characteristic Compressive strength(fck) of the concrete in N/mm2 @28 days when checked with 15cm×15cm×15cm cube in direct compression test. Concrete is a composite mixture which consists of Cement, Sand and Aggregate. As we know that during concreting when we place wet concrete, it gets harden after certain standard time. Nominal mix concrete Traditional way of mix proportion specified in terms of fixed ratios of Cement : Sand : coarse aggregate (In general by volume) 4 2.5 â¢Useful for small works â¢Useful for routine concrete construction â¢Limited up to M20 grade â¢Requires high cement content 0000003209 00000 n Concrete mix design is the process of finding right proportions of cement, sand and aggregates for concrete to achieve target strength in structures. Large constructions such as Bridges, dams requires huge amount of concrete, using the right quantity of constituents make the structure economical. of Cement Bags required for 1m3 of Concrete = 403/50 = 8.06 ~ 8 bags. High strength concrete becomes high performance concrete with right concrete mix design. design procedure.
