Experimental investigation on mechanical behavior of geopolymer light weight concrete

ABSTRACT

The development of lightweight geopolymer concrete is the main goal of this research work, and the outcomes were evaluated in comparison to the control mix. In this work, geopolymer concrete was produced using fly ash as a binder, synthetic sand as M-sand as fine aggregate, and coconut shell as well as palm shell ash for coarse aggregate. For the purpose of selecting a mix proportion via trial mixes, an initial investigation was conducted. The quantity among binder, fine and coarse aggregate, sodium hydroxide molarity, sodium silicate: sodium hydroxide ratio, the alkaline binder ratio is some of the significant variables taken into account in the current study. Investigation of the effects of various factors on the engineering characteristics of geopolymer concrete. The trial mixes were utilized to evaluate the characteristics for geopolymer concrete with a ratio of 1: 2.36 :1.02 and a Molarity of 16 with binder ratio 0.6 The key findings of this investigation is to that the coconut shell waste and palm shell can be replaced instead of fine aggregate. In-depth research was done on the mechanical behavior with geopolymer concrete, such as the mechanical and durability characteristics with control mix.
