2020/10/02For a good fine aggregate, the FM should be between 2.3 and 3.1 (ASTM Range for fine aggregates). A FM of 4 can be interpreted to means that the fourth sieve from bottom i.e. sieve No. 16 is the average size of the aggregate particles in the given sample. Get price >>
2021/01/22Higher the Aggregate/Cement ratio leaner the concrete mix, as cement content is lower. Concrete mix can be made more workable by fine tuning Aggregate/Cement ratio. The same is governed by particle size and shape of aggregate used. Get price >>

2017/11/24Concrete mix design is the process of finding the proportions of concrete mix in terms of ratios of cement, sand and coarse aggregates. For e.g., 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 [] Get price >>
