What is the difference between fine aggregate and coarse ...

A small number indicates a fine grading, and a large number indicates a coarser material. The fineness modulus of the fine aggregate is required for mix proportioning, since sand gradation has the largest effect on concrete workability. Concrete made with a fine sand (low fineness modulus) has much higher paste requirements for good workability.
