Abstract
The aim of this study was to use industrial by-products such as micro silica and cenosphere as replacement for cement and fine aggregate respectively to produce M55 grade concrete. One of the main problem associated with high strength concrete is autogenous shrinkage due to low water-binder ratio and hence a study was conducted by addition of non-perforated and perforated cenosphere in to M55 grade concrete mix as a replacement of fine aggregate (5% and 10%). Specimens were casted by addition of cenosphere (perforated and non-perforated) in to the control mix of M55 grade concrete obtained by addition of micro silica as cement replacement and were tested for fresh property and hardened properties after 28 days. Present investigation focuses on studying and evaluating the performance of M55 grade concrete and M55 concrete which is modified by addition of cenosphere in terms of workability, density and compressive strength. Thus exploring a new internal curing agent and this promotes sustainable development.
