Abstract
In India, masonry structures are still practiced on major scale. Causalities majorly happens in masonry structures during earthquakes in earthquake prone zones due to less bond strength and non-structured designs. The main aim of afore mentioned paper is to find solution to increase this compressive strength, so that practice of masonry structures in rural area can made safe and economic with respect to strength. This study of bond strength can be carried out by analytic approach as well as experimental approach. In analytic approach, finite element method is used for the study, which requires large numbers of properties to model materials, which are not available in literature for the Indian scenario because literature focuses about results not properties. Hence this compressive strength study is carried out by experimental approach to give it more practical and meaningful direction. In mortar, arbitrarily dispersed fibers and alccofine 1203 are generally used for fortification to resist proliferation of crack and also helps to improve strength and ductility behavior which will help the structure to get less damage and to enhance the performance during earthquakes in earthquake prone zones. This will reduce the causalities. The use of recron 3s fibers is economic and alccofine 1203, easy to practice and effective approach as well. These experimental studies are started by making mortar cubes and ended up with making masonry prism and columns by using recron 3s fibers and alccofine 1203 with different mortar bed thicknesses. The studies on brick masonry prism suggests that use of recron 3s fiber and alccofine 1203 in mortar can increase the compressive strength to enhance the performance of the masonry structure. Use of 8 mm thick mortar bed gives more convincing when compressive strengths of masonry wallets are compared.
