Strength of light weight concrete containing fly ash cenosphere

Abstract

The study's main focus is on finding a modern substitute for grit in light-weight concrete (LWC). The researcher is concentrating on partly replacing sand with readily available solid wastes like cenospheres, which are likely to support waste management and also provide a potential replacement for the most exploited. Three different series of mortar cubes with three identical specimens each were used in the experimental research. The observed outcomes have demonstrated the better compatibility of using fly ash up to 25% and cenospheres at 30% as a sand replacement in LWC with improved strength characteristics. In the construction of concrete structures, Light Weight Concrete (LWC) is quickly gaining acceptance for a variety of uses. When building concrete structures, Light Weight Concrete (LWC) is quickly becoming satisfactory for a variety of uses. Fly ash and cenospheres are added to concrete to improve its workability, strength, and longevity. They serve as pozzolanic components. In order to determine the best replacement for mineral admixtures like fly ash and bagasse ash in concrete, various ages of the materials were used to examine the strength characteristics such as cube compressive strength, cylinder compressive strength, and split tensile strength. The ideal replacement amount of fly ash and cenosphere was determined after comparing the strengths. According to the effects of the various fly ash and cenosphere fractions used to substitute the sand, the mechanical properties change to utilise cenosphere and fly ash.
