This makes it economically impractical to build up subgrade strength with thick layers of crushed stone or gravel.
THE WATER TO CEMENT RATIO Too much water and not enough cement means concrete will be weaker and less durable. The water to cement ratio (W/C) is the weight of the water divided by the weight of cement. Water 20 litres W/C = ie = Cement 40 kg The lower the ratio, the stronger the concrete.
