What sets perlite apart from other volcanic glasses is that when it is heated to its softening range, it expands from four to twenty times its original volume. This expansion is due to …

Crude perlite is ground. and subjected to the short thermal treatment at temperature 900–1000 C. This results in expandation of material due to the presence of 2–6 % chemically bound water releasing with the formation of numerous pores in the structure. The pores are surrounded by an amorphous, sintered mass.

It was explained by a significant impact of ground expanded perlite on the loss of concrete mix fluidity. Therefore, despite using superplasticizers, at low water to binder ratios (<0.35) the hardened concrete showed increased porosity and therefore lower density and strength [18]. As per test results, application of the ground EP as an
