Development of regression equation for optimizing the materials requirements of lime and sand stabilizing adobe based on consistency and linear shrinkage

This study investigate the determination of optimum quantity of materials required for construction of adobe by using stabilizing agent such as lime and sand with clay content. Lime was used for giving adhesive strength and sand was used to reduce the linear shrinkage of adobe. The aims of this study is to analyze the effect of the stabilizing agent on consistency and linear shrinkage behavior of adobe making clayey soil collected from Khulna region in Bangladesh. Besides that, regression equations were developed to quantify the materials required for a designed consistency and shrinkage of adobe and also to optimize the materials quantity, which makes the soil much more consistent and increase the ability against linear shrinkage.
