Study on the Compressive Strength of Lime Mortar Using Admixtures

Abstract

Lime is a binding material which is used from ancient times for the construction of buildings. Since the strength of lime is very less compared to cement, cement has been used as the major construction material. Due to environmental aspects, there is a need to reduce the usage of the cement in the construction industry. So, in this study an effort is made to improve the strength parameters of the lime mortar by using natural admixtures. The natural admixtures that are found to improve the strength are kadukkai and Jaggery. The compressive strength of varying proportions of admixtures is found out by experimental study and the values are compared with the conventional lime mortar. The proportions of admixtures are varied from 2.5% 5% 7.5% 10% 12.5% and 15%. The results show that the admixtures improved the strength of the lime mortar.
