#CONCRETE MIX DESIGN CALCULATOR XLS TRIAL#
Now add fine aggregate ( sand ) in trial mix drum and then add the cement.After weighing materials, put coarse aggregates 20 mm and 12.5 mm first in the trial mix drum.Take the weights of all material as described above.Now we calculate the quantity of materials for a trail mix.Īdmixture = 1.8 x 0.045 = 0.081 kg Trial Mix Procedure We should not take more quantity for the concrete trail mix because it doesn’t mix properly.Īs we calculated materials weight before for one cum. So assumed concrete quantity = 0.045 cum. We should take a little more quantity of concrete because it will stick on a trial mix drum and slump test purposes. So concrete quantity for 1 cube = 0.003375 cum.Ĭoncrete quantity for 12 cubes = 0.003375 x 12 = 0.0405 cum. You can increase the cube numbers for three3 days, 7 days, or 28 days as per your requirement.

To check the compressive strength of trial mix concrete, we have to cast at least 12 nos. Proportion of cement, coarse aggregate, fine aggregate, water, and admixture ( if required ).

In this trial mix, we design the following. We are describing here trial for M30 Grade of Concrete Mix Design, but you can use this trial procedure for any grade of concrete. The trail mix is required to define the workability ( slump ), density, compaction, and, most of all, the compressive strength of different concrete grades for various purposes. Trial Mix:1, (For M30 Grade Concrete Mix Design)

In moisture correction, Weights of Aggregate and water can be replaced by the weights of the free moisture on Aggregates. for M30 Grade of Concrete Mix Designĭosage of admixture, by the Weight of Cement This formula can be used for any grade of concrete mix design.įormula = material weight = material volume x percentage of total volume x material sp. Now we got a volume of each material for use in concrete.Ĭonvert Volume into Weight for Concrete Mix We are describing formula of concrete mix design calculation for M30 Grade of Concrete Mix Design but you can use this formula for any grade of concreteįormula : Volume of material content = material weight / ( material specific gravity * total volume )Ĭement Content = 360 / 3.15 x 1000 = 0.114 Cu.M. Hence Coarse aggregate content for MSA 20 mm: 60%Ĭourse Aggregate Proportions ( 20 mm : 10 mm ) : 50% M30 Grade of Concrete Mix Design Calculation Formula Proportion of Volume of Coarse and Fine Aggregate Content for M30 Grade of Concrete Mix Design
