Then, we obtain the free-water/ cement ratio from table 1. For OPC ( 7 days ) using crushed aggregate, water/cement ratio 36 N/mm2. After that, from the figure 2, the curve for 42 N/mm2 at 0.5 free-water ratio is plotted and obtained the free-water ratio is 0.45 at the target mean strength 43.12 N/mm2. Concrete Trial Mix 2 To increase the workability from 25 mm to 50-75 mm an increase in water content by 3% is to be made. The corrected water content 191.6 x 1.03 197.4 kg. As mentioned earlier to adjust fresh concrete properties the water cement ratio will not be changed.

And, fresh concrete mix of quarry dust concrete showed lower workability than river sand concrete for 124 mix ratio and water-cement ratio of 0.55. The higher slump interposed for quarry dust may be due to higher sand content in quarry dust.

Concrete Mix Ratio Calculator. An online on site concrete calculator to calculate the concrete mix ratio. It plays a major role in creating a strong, durable concrete block. The major materials needed in the preparation of concrete blocks are portland cement, sand, aggregate (stone), and water. Additionally, it was shown that a higher porosity of the concrete, e.g., due to a higher w/c ratio, also results in a lower electrical resistivity. These results are in agreement with the ...
