4.2. Based on Fineness Modulus: The fineness modulus is also considered as the indi ion of quality of aggregate. According to IS recommendations the aggregate should posses the F.M to the range of 2.6 to 3.2. Greater than 3.2 should be rejected. The Classifi ion of sand based on Fineness modulus is as follows,

While trial batches are still recommended for previously unused aggregates the modifi ion proposed for the old fineness modulus method permits the design of equally workable batches of varied cement contents from data on trial mixes of a single cement factor. This materially reduces the number of test batches where a range of cement contents is to be used with a set of aggregates. The method ...
