concrete mix design

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. And then present those amount as a ratio. You can also watch our video here: Video on concrete mix ratio of various grades of concrete. In return, We feature your name in author box with your social links. The total sum of these percentages divided by 100 gives the fineness modulus. Accurate concrete mix design makes concrete construction more economical. Dear Admin, This is very impressed and useful information to civilians. kindly add my mo no. Therefore, it cannot and should not be used interchangeably with concrete mix design. Comprehensive Excel spreadsheet for concrete mix design and batching can save up to 100 mixes. Concrete mix design is the procedure for finding the right quantities of these materials to achieve the desired strength. Concrete mix design (CMD) is therefore scientific and systematic process of choosing economical relative proportion of various ingredients from available material which gives cohesive concrete of desired workability in fresh stage and desired strength and durability in hardened stage. The following steps are followed to find the quantity of sand in  1m3 of concrete. Accurate concrete mix design makes concrete construction economical. The design begins by determining the requirements of the concrete. It is the usual method used for designing mixes for producing controlled concrete. 1326 kg of 20mm Aggregate is required for 1 cu.m of M20 grade concrete. Concrete mix design is a method of calculating right proportions of cement, sand, and aggregates for concrete to achieve target strength in structures. It is suitable for both ordinary and standard grades of concrete having compressive strength of 55 MPa (28-day strength) and slump range for workability 25 to 125 … 1 Concrete mix design for M45 2 Type of cement used OPC 53 grade cement conforming to IS 269 3 Maximum nominal size of aggregate : 20 mm. For M25 grade concrete the target mean strength = 31.6 MPa. All these make the task of mix design more complex and difficult. Hence we require 672kg of sand  for 1 cu.m of concrete. Concrete Mix design illustration for M25: f t.m.s = f ck + t X s = 25 + 1.65 X 4 = 31.6 MPa. What you have done is calculation of quantity of materials for nominal mixes of different grades. What is Construction Contingencies and Why It is Required. 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. Important Thumb Rules used in Construction by Civil Engineers, How to calculate Volume of concrete for Slabs, Columns, Beams, Retaining wall & Footings, https://forum.civilread.com/question/whats-the-gap-graded-agg/, Compressive strength test on Building materials, Quality check of building materials on site. The methods are: 1. For making concrete, required amount of water is added. For a mix design of concrete, we have to follow various steps, calculations, and laboratory testing to find the right mix proportions. In the Concrete Mix Design process each and every ingredient of concrete is tested in laboratory.
