Abstract

An attempt was made to utilize the Egg Shell Powder (ESP) as a partial replacement for cement in concrete. ESP is a finely divided powder resulting from the grinding of cleaned and oven dried egg shells. The properties of ESP were found by the standard test procedures. It has more lime content so it can be effectively replaced for cement. Egg shells are known to have good prospects in minimizing the usage of cement. M20 grade concrete specimens were casted from 0 - 20% replacement of cement by ESP. The compressive strength of concrete varied from 27.96 N/mm2 to 10.73 N/mm2 respectively, after 28 days of curing. The splitting strength of concrete varied from 5.05 N/mm2 to 3.19 N/mm2 respectively, after 28 days of curing. The flexural strength of concrete varied from 4.91 N/mm2 to 3.28 N/mm2 respectively, after 28 days of curing. The mechanical strength properties satisfy the regulations, reinforcing the safety and suitability of utilizing the ESP in concrete. Based on the study 10% replacement was found to be optimum.
