This is a Volumetric Calculation. The specification should also say if those proportions are by weight or volume. In a nominal mix quantity of cement, sand and aggregate are fixed. Previously the specification for concrete was proportion of Cement, Sand and Course Aggregates. Also, Read – How to Calculate Cement, Sand and Aggregate in Concrete? I hope now you understood how to calculate quantity of material for different concrete mix ratio. The values of fineness modulus more than this value make the concrete harsh, while a lesser value leads to an uneconomical mix. Step #2. If I have missed any information related to concrete mix ratio, you can mention it in the comment section. Concrete mix design is process of preparation of concrete with suitable proportion of ingredients to meet the required strength and durability of concrete structure. M15 = 1:2:4 M20 = 1:1.5:3 M25 = 1:1:2. Determine the proportion of fine aggregate according to the fineness of fine aggregate, maximum aggregate size, slump/Vebe time and W/C. The relation gives the proportion of the amount of fine aggregate (W) to be mixed with one part of the coarse aggregate. The fresh concrete properties like workability, setting time and hardened concrete properties like compressive strength, durability etc. It is best to use the ratio printed on the sack, but if none is given use 1:2:3. The design mix which is prepared from suitable ingredients in respective proportions itself improves the concrete properties. However, this method is simple and, if carefully considered, gives relatively satisfactory results. The mixture that shows the smallest volume for the same weight means one, which is the densest, is adopted. Concrete Ingredients Calculation. The proportion of the material is determined by the concrete mix expert in this method. Sand. The C20 concrete mix is a medium-strength concrete recommended for basic household constructions such as retention of posts, garden walkways and many more. It’s terrific to read an informtive article of some actual valuue to me. I have a residential-concrete specification that calls for a 1:2:4 concrete mix. 1:2:4, 1:3:6 are arbitrarily chosen by volume. Every ingredient of concrete consists different properties so, it is not an easy task to get economical and good concrete mix. It starts from M5 and goes up to M40. Designed Concrete Mix/Ratio. If I remember correctly, 1:2:4 concrete ran 2500 psi for the higher slumps and up to 3500 psi for the low to medium slumps. Concrete with good quality improves its properties such as strength, durability etc. The fixed ratio of these was to ensure the strength to the structure. Similarly, we can calculate the quantity of materials for different mix ratios. The design is done according to the requirements of concrete strength. Since DOE method presently is the standard British method of concrete mix design, the procedure involved in this method is described instead of out dated Road Note No 4 method. The proportions are either by volume or by mass. The proportion of the material is determined by the concrete mix expert in this method.

Mix ratios are decided based upon the type of construction structures and mix designs. For example if the concrete mix is of M20 Grade then the compressive strength will be 20 MPa. 1:2:4 therefore means, 1 part of cement : 2 part of fine aggregate : 4 part of coarse aggregate. The coarser the aggregate higher will be the fineness modulus while finer the aggregate lower will be the fineness modulus. Mixing Ratio is 1:1.5:3 ( 1cement part: 1.5 sand part: 3aggregate part). Water = 98.93 litres. The major materials needed in the preparation of concrete blocks are portland cement, sand, aggregate (stone), and water. now come to the ratio of concrete which is 1:2:4 so sum of the ratio will be 1+2+4=7 calculating separately each material: Cement: 1/7x154 = 22 cubic feet where 1 bag of cement measured 1.25 cubic feet approx therefore 22/1.25 = 17.6 bags of cement. Welcome to YYQX. The water used also is of good quality generally potable water is used. While Road Note No 4 or Grading Curve Method was specifically developed for concrete pavements, the DOE method is applicable to concrete for most purposes, including roads. What are the Properties of fresh Concrete? Concrete mix design belongs to the method of determining the ratios of concrete mix in terms of proportions of cement, sand and coarse aggregates. M15 = 1:2:4. Sometimes, a different cement:sand:gravel ratio such as 1:2:4 or 1:2:2 is printed on a sack of cement as a guideline for making concrete slabs. With the right amount of water and additives added in, this should result in a reliable mix that is appropriate for slab creation. Concrete Mix Ratio Calculator. The C20 concrete mix is a medium-strength concrete recommended for basic household constructions such as retention of posts, garden walkways and many more. In 1975 the note was replaced by the “Design of Normal Concrete Mixes”, published by the British Department of the Environment (DOE). M20 = 1:1.5:3. To do this, add slightly more aggregate so that you have a 1:2:4 ratio. If you found this informative, please don’t forget to share it. Just to keep everyone shaking their heads, My father & I used that proportion to place some in-fill slabs around the house in 1968, kept the slump low and had 4000 psi concrete. 0.45 for 1 : 1 : 2 concrete; 0.5 for 1 : 1.5 : 3 concrete; 0.5 to 0.6 for 1 : 2 : 4 concrete. – Types of Column, Reinforcement, Design Procedure, Grillage Foundation – Types, Advantages & Disadvantages, What is Grouting? For M-15 grade concrete (1:2:4) Cement = 6.336 bags. Where fine aggregate could be Sharp Sand or Stone dust and Coarse aggregate could be granite, gravel or stone-base (for certain project types). Therefore, Cement Quantity = (Cement Part / Concrete Parts ) * Concrete Volume The strength of nominal mix concrete varied widely for given workability due to variation of mix ingredients. From various experiments, specific values of fine, coarse, and mixed aggregate prove to be more economical than others, with the least amount of cement.
