摘要

Abstract This work highlights the reactivity of soda-lime glass powder on cement CEM IV-B-L 32.5R. Three colors of soda lime glass were used with varying amount of powder from 0 to 35 wt. The water demand for standard consistency have increased from 28.40 to 45.93 wt. The compressive strength increased from 26.46 to 31.66?MPa and the flexural strength also increased from 5.89 to 7.14?MPa after 28?days. The optimal value of 10 wt of glass powder gave the maximum value of mechanical strength at 28?days. The soda lime glass powder obtained from waste breweries drink bottles improves mechanical properties of cement up to 25 wt due to the pozzolanic reaction. The excess of soda lime glass powder up to 25 wt reduce the lime saturation factor, increase significantly the quantity of equ Na2O (Na2O?+?K2O) in the mixture, increase the silica modulus and reduce the hydraulic modulus that affecting the mechanical strength of soda-lime glass cement.
