Sand Concrete Content

If you prepare concrete with your ration then the concrete will have too much sand Too much sand causes shrinkage and this will not give highdensity concrete Hence use 123 for good strength and 12535 for moderate strength If you want to increase strength then reduce the water content and use Chemical admixtures like super plasticisers
