what are the ratios for fine aggregate concrete

Construction aggregate WikipediaDesigning Concrete Mixtures Civil Engineering

Construction aggregate or simply aggregate is a broad category of coarse to medium grained particulate material used in construction including sand gravel crushed stone slag recycled concrete and geosynthetic aggregatThe lower the w/c ratio the higher the concrete strength Whereas strength depends on the w/c ratio economy depends on the percentage of aggregate present that
