Influences of Eggshell Powder to reduce the collapse of soil gypsum

Abstract

Failure of different buildings built in the regions of gypsums soils in Iraq, particularly in the last three decades lead to find strategic projects to solve this problem. for this purpose, selected regions of gypsums soils in Iraq to study and find conclusions of gypsum. The investigational work includes testing of collapse soil before and after mixing gypsum soil with deferent percentage of eggshells powder (4%,8%,12%, 16% and 24%) and the cruelty the collapse potential classification. the soil before mixing is considered as Severe trouble, while after mixing the soil become no problem at 16% of eggshells powder.
