Experimental investigation on concrete using animal bones as a partial replacement of coarse aggregate in addition of alccofine as an admixture

Abstract

An experimental study of the suitability of the machine crushed animal bones as a partial replacement for coarse aggregate and in addition to alccofine as an admixture in concrete works has been carried out. This project mainly focused on the preservation of coarse aggregate for future generation and the concrete works has been carried out in the reducing construction cost. Mechanical tests like compression, spilt tensile, flexural strength test conducted on cubes, cylinders of M20 concrete and cured for 14 days and 28 days. The samples were immersed in normal water and sea water for the purpose of curing and replacement level of normal coarse aggregate with animal bone by weight and comparative study has been made between normal concrete and animal bone concrete along with alccofine additive. From this experiment the use of alccofine found to increase the strength, workability, mechanical, durability properties and reduce the heat of hydration, segregation and permeability of animal bone concrete.
