INFLUENCE OF TERMIANALIA BELLERICA ON AIR LIME MORTAR: FRESH STATE PROPERTIES AND STRENGTH ANALYSIS
The rehabilitation practice of historical structure is growing trend in current scenario, consists of restoration and maintenance. One of the practices is replacing the damaged material with a modified material of compatible characteristics. In this study use of sustainable, eco-friendly and economical natural polymer admixture is encouraged. The polymer extract which is incorporated into the lime mortar is Terminalia bellirica known as Belleric myrobalan. The main aim of this study is to study the change in fresh state properties and mechanical properties of air lime mortar using natural admixture. The admixture added in the air lime is added in different concentrations of 3% and 5%. The fresh state properties such as consistency, workability, and setting time test were done on modified air lime. The mechanical properties such as compressive, flexural strength test were done after 28 days. The admixture found to be influencing the properties on air lime to a greater extent. The addition of natural admixture showed positive result in the fresh state and mechanical properties when compared with the conventional mortar.
