Abstract
Geopolymer is formed as result of reaction of two materials containing aluminosilicates and a concentrated alkaline solution to produce an inorganic polymer binder. The geopolymer cement is categorized as environmentally friendly, more durable, and has higher mechanical properties compared to ordinary Portland cement. The aim of this study is to investigate the possibility for utilization of aluminosilicate wastes such as ceramic (CW), red clay brick (RCBW) and concrete wastes (CoW) as well as ground granulated blast furnace slag (GGBFS). Firstly, the GGBFS was activated using mixture of 3wt. % sodium hydroxide (NaOH) and 3wt. % liquid sodium silicate (Na2SiO3). Also, the effect of CW, RCBW and CoW on the physico-chemical and mechanical properties of alkali activated slag (AAS) has been studied. The results showed that, the CW, RCBW and CoW potentially affect the physico-chemical and mechanical properties of AAS. Secondly, the possibility for the production of geopolymer resin by alkali activation of CW, RCBW has been investigated. In this part, CW was activated by 3&3, 6&6, 9&9, 12&12 and 15&15 wt. % NaOH &Na2SiO3. The results showed that, the compressive strength increases with increase alkali content. All CW specimens activated 3&3, 6&6, 12&12 and 15&15 wt. % NaOH &Na2SiO3 are destructed after 24h of water curing. Alkali activated CW containing 9&9 wt. % NaOH&Na2SiO3 gave relatively higher compressive strength with good resistivity to water curing. The compressive strength of alkali activated RCBW are higher than that of alkali activated CW. In order to produce geopolymer cement, alkali activated CW and RCBW was replaced by 10 and 30 wt. % CoW and GGBFS. The results have been showed that, the compressive strength of alkali activated CW or RCBW decreases with the increase of CoW content up to 30 wt., %. Different instrumental analyses such as XRD, FTIR and SEM are applied to investigate the hydration products formed along geopolymer matrix.
