The goal of pavement design is to specify the characteristics required for quality performance for a given application two key components are mix design and structural design these processes must also take into account external parameters including subgrade characteristics, traffic loading, and the environment. Sir i want to know how can we calculate the quantity of water required for mix design example for full details mix design what is 32 ,33, please tell us four mulla read more guys its not design mix but it is nominal/standard mix where values are already standardized and given he is making. 3)the water cement ratio should be 045 of all mix 4)mix the all ingredients such as cement ,affregates and water 5)after mixing the freshly mixed concrete should be used for its application the initial setting time of concrete is 30 mins and final setting time sholud be less than 10 hrs so this was about the mix design for m20. Concrete mix design is the process of finding the proportions of concrete mix in terms of ratios of cement, sand and coarse aggregates for eg, a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the ratio 1 :2:4 or the mix contains one part of cement, two parts of fine.
