Experimental Study on Fresh Properties of Self Compacting Geo Polymer Concrete using Vermiculite as Fine Aggregate at Various Levels of Replacement

This investigation is mainly focused on the preliminary study on fly ash (FA) and ground granulated blast furnace slag (GGBS) based GPC using vermiculite (VM) as fine aggregate replacement at various levels (0%, 10%, 20%,30% ,40% and 50%). In this study, sodium silicate (Na2SiO3) and sodium hydroxide (NaOH) solution is used as alkaline activator. Test results revealed that the increased replacement level of vermiculite decreased the GPC properties. It can be concluded that the replacement levels of VM can be chosen based on the strength requirement GPC as per the requirement. The SCGC is suitably designed for vermiculite replacement with fine aggregate Up to 30% only and remaining percentage of vermiculite is not suitable like 40% and 50% Last and finally we are concluded 10%,20% and also 30% of vermiculite of fine aggregate is suitable for self-compacted geo polymer concrete (SCGC).
