Cumulative percentage of weight retained on all the six sieves = 292 Fineness Modulus of Fine Aggregates = 292/100 =2.92 kg. Now, when it is desired to obtain a combined aggregate of a definite (required) fineness modulus, F, the amount of fine aggregate (x) to be mixed with 1 volume of the coarse aggregate of a given fineness modulus can be easily determined from the relationship:

You can often save money by selecting the maximum allowable aggregate size. Using larger coarse aggregate typically lowers the cost of a concrete mix by reducing cement requirements, the most costly ingredient. Less cement (within reasonable limits for durability) will mean less water if the water-cement (w/c) ratio is kept constant. A lower water content will reduce the potential for ...
