Geopolymer Concrete, Silica Sand, Mechanical Properties


The demand of cement (OPC) is increasing for satisfying the need of development of infrastructure facilities. OPC production releases more quantity of carbon dioxide to the atmosphere, it is harmful to the human health and also pollute environment. Therefore, it is essential to find alternatives to make the concrete environment friendly. In this respect, Davidovits (1988) proposed an alternative binder for the concrete technology and it shows a good results. These binders are produced by an alkaline liquid reacts with the silica (Si) and aluminium (Al) present in the source materials. The technology proposed by the Davidovits is commonly called as Geo-polymers or Geo-polymer technology. This paper presents the study on Mechanical properties of GPC of class f fly ash (FA-50%) & GGBS(50%) based GPC using silica sand as sand replacement at different levels ( 0%,10%,20%&30% ). These properties have been tested for 7, 28&90 days curing at ambient room temperature. From the results, it is concluded that the increased replacement level of Silica Sand from 0% to 20% increased the mechanical properties of GPC mixes.
