CONCRETE MIX DESIGN USING CRUSHED SAND

Mix design aims to achieve good quality concrete at site economically. I. Quality concrete means • Better strength • Better imperviousness and durability • Dense and homogeneous concrete II. Economy a) Economy in cement consumption It is possible to save up to 15% of cement for M20 grade of concrete with the help of concrete mix design. In fact higher the grade of concrete more are the savings. Lower cement content also results in lower heat of hydration and hence reduces shrinkage cracks. b) Be
