L’effet de la substitution progressive de 10 % \u00e0 50 % du volume de ciment par le laitier granul\u00e9 et la pouzzolane naturelle sur les propri\u00e9t\u00e9s physico-m\u00e9caniques des p\u00e2tes et des mortiers \u00e0 base de verre recycl\u00e9 a \u00e9t\u00e9 \u00e9tudi\u00e9. L’effet de ces additions sur la consistance et les temps de prise des p\u00e2tes de ciment ainsi que sur les propri\u00e9t\u00e9s physiques et m\u00e9caniques des mortiers a \u00e9t\u00e9 determin\u00e9.

Elle provoque aussi un besoin en eau important. Elle am\u00e9liore les propri\u00e9t\u00e9s m\u00e9caniques et la rigidit\u00e9 des mortiers et peut r\u00e9duire les expansions et les pertes de performance m\u00e9caniques dues \u00e0 la RAS.<\/p>\n
