Pressed lightweight concrete containing calcined diatomite ...

At the high temperature of 1000 °C, the coarse aggregate was stable and strong and this contributed to the strength of the pressed lightweight concrete. At the calcination temperature of 600 °C, the fine diatiomite aggregate was reactive. Calcined diatomite is a suitable lightweight aggregate for making pressed lightweight concrete blocks.

Sieve analysis - Wikipedia

A sieve analysis (or gradation test) is a practice or procedure used (commonly used in civil engineering) to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass.
