To calculate water-cement ratio for mix design we need to collect some data like. Target mean strength of concrete. We can calculate it from ft = fck 1.65 S. where fck – The characteristic compressive strength of concrete Grade of concrete which you want to design S – The standard deviation obtained from the below table

You will need: 24.93 bulk bags of this aggregate type. You will need: 935.00 mini bags of this aggregate type. The exact conversion depends on a number of factors beyond our control for example moisture method and degree of compaction type of sub-base etc.
Step-2-Batching of aggregate by volume Gauge Box. A gauge box is used as shown in the picture for batching of fine and coarse aggregate by volume. The box should not be too shallow. It should be completely filled with aggregates. The top of the materials should be struck off level with a straight edge.
The concrete mix design available on this site are for reference purpose only. Actual site conditions vary and thus this should be adjusted as per the lo ion and other factors. These are just to show you how to calculate and we are thankful to all the members who have emailed us these mix designs so that these could be shared with civil
Mix design with Cement and Fly Ash 133 lbs. fly ash 667 Total lbs. Cm = 20% ash It’s about volume Note: lower water demand due to fly ash - for same slump Mix design with Cement and Fly Ash Proportion the mix to yield 27 ft3 … but how much sand stone … what ratio? Sand / Aggregate ratio is by volume It’s about volume
Understanding Concrete Grades . Based on strength concrete is classified into different grades like M5 M7.5 M10 M15 M20 etc. In concrete grades the letter “M” stands for “Mix” and the following number stands for characteristic compressive strength of concrete in 28 days in the Direct Compression test.
Sand–aggregate ratio water dosage and water–cement ratio are three basic parameters for the calculation of concrete mix proportion. Amongst them water–cement ratio can be calculated with the help of Bolomey formula but sand–aggregate ratio and water dosage are mainly determined by referring table which are fairly arbitrary.

The last step in the calculations adjusts the amount of water in the mix design based on the input of the moisture content and degree of moisture absorption of coarse and fine aggregates. It is important to consider the amount of water the aggregates give to the mix and retrieve from the mix because this causes variation in the water/cement ratio.

We will show you how to use this formula in our final example. Volume With Custom Density; Let’s imagine that I want to fill a space measuring 40 ft³ with a custom aggregate costing $20 per ton. I am unsure of its density but when buying by bulk the sand weighs 240 pounds per 4 cubic feet. I can therefore calculate its density:
