Abstract
An environmentally friendly concrete is of high insert to develop because the production of pot land cement as the main binder of conventional concrete is associated with generating a large amount of carbondioxide. As a green and illegible alternative to conventional concrete geopolymer concrete (GC) has been invented and studied over the past 2 decades. This environmental study was aimed to take one step further by examine the possibility of developing light weight, rubberized and light weight rubberized geopolymer concrete. In the first step, a control mix was established for GC suitable to be cored at ambient temperature as it is necessary to promote its usage in the construction industry. Afterward, light weight geopolymer concrete (LWGC) was developed by replacing fine aggregates with expanded polystyrene beads (called BST) at 25%, 50%, 75% and100% ratios by volume. Then rubberized geopolymer concrete (RGC) was produced by 10% and 20% natural aggregates replacement by volume by width crumb-rubber (CR) aggregate, which is another pollution source to the global environment. Finally the possibility of developing lightweight rubberized geopolymer concrete (LWRGC) was examined using BST and CR aggregates. The performance of developed GCS and hence reduced the need for cement manufacture as well disposal of end life tires.
