Fresher Engineer Should Know Reality of Industry & Demand for Skills before INVESTING Money In this video Er. Kishan Ojha, Corporate Trainer of Civil Guruji explaining about M25 Concrete Grade | How to Calculate Cement, Sand, and Aggregate for Mix Design Concrete is a composite mixture which consists of Cement, Sand and Aggregate. Concrete mix design is the procedure for finding the right quantities of these materials to achieve the desired strength. Accurate concrete mix design makes concrete construction economical. Large constructions such as Bridges, dams requires huge amount of concrete, using the right quantity of constituents make the structure economical. In order to calculate or find the right amount of cement, sand and aggregate required in 1m3 of concrete; you need to know about different grades of concrete. M25 Concrete Grade | How to Calculate Cement, Sand, and Aggregate for Mix Design || By CivilGuruji 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 of the concrete in N/mm2 @28 days when checked with 15cm×15cm×15cm cube in direct compression test. M25 Concrete Grade | How to Calculate Cement, Sand, and Aggregate for Mix Design || By CivilGuruji Concrete Mix design of M5, M7.5, M10, M15, M20, M25, M30 and higher grades of concrete is calculated as below: The procedure for finding the different grades of concrete mixes are same. The below mentioned method can be applied to any grade of concrete by changing the values. To make ease in understanding we are finding the Concrete mix design of M20 grade concrete. M25 Concrete Grade | How to Calculate Cement, Sand, and Aggregate for Mix Design || By CivilGuruji 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. Nominal Mix is generally adopted for small scale constructions. In this type of mix, the mix ratios and concrete constituent proportions are prefixed and specified. Eg: M20(1:1.5:3); the quantity of cement, sand and aggregate is batched in volume as per the fixed ratio 1:1.5:3. M25 grade, the concrete proportions are called as Nominal mix concrete. #civilguruji #Engineering #Construction #Concrete #Grade #Calculate #Cement #Sand #Aggregate M25 Concrete Grade | How to Calculate Cement, Sand, and Aggregate for Mix Design
