Influence of granite fine powder on the performance of cellular light weight concrete

As increasing the utilization of granite stone wares, the quantum of granite fine powder substantially increases these days, causing social and ecological issues to the society. This research attempts to use granite fine powder (GFP) as an alternative resource of raw material for making foam based cellular light weight concrete (CLWC). The weight ratios of GFP and binder used in this present study were 0.8:1, 1:1, and 1.2:1. Three different foam-binder ratios, such as 0.025, 0.05 and 0.1 were used in this study. The outcomes obtained from experimental study showed that, comparing with GFP-binder ratio, the foam-binder ratio have a predominant effect on bleeding capacity, flowability, strength, absorption and permeable voids of CLWC. The voids distribution of CLWC during fresh and hardened states is considerably influenced by GFP-binder ratio and foam-binder ratio as inferred from microscopic image analysis. The experimental investigation of this study addresses consensus behavior of GFP based CLWC from materials point of view.
