The raw material used is thus collected (cleaned bottles glass of same type) then manually broken into small pieces. Once crushed, the obtained material is sifted through a series of screens, according to AFNOR standards. By separating the different sieve fractions, we selected the fraction with the same particle-size characteristics as our sand, in accordance with the coefficient of uniformity and the coefficients of classification, as shown in figure (1). Various physico-chemical parameters of the studied glass are grouped in Table (2)
