The fineness of the original sand used in a concrete mixing plant

Quality Control of Ready Mixed Concrete - IOSR Journal

Construction sites have limited equipment in their quality control laboratory. Hence Ready-mix concrete (RMC) is a ready-to-use material, with predetermined mixture of Cement, sand, aggregates and water. Initial setting time The fly ash fineness is determined by wet sieving through a 45 micron sieve following Indian

What is Fineness Modulus of Sand (Fine Aggregate) and Calculation

Fineness modulus of sand (fine aggregate) is an index number which represents the mean size of the particles in sand. It is calculated by performing sieve analysis with standard sieves. The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fineness modulus.
