Abstract: In India, the construction field streams towards the hike with the advent of new innovative technologies. The increase in the quantity of construction seeks the superior quality from the researchers in terms of effective methodologies which reduce the requirement of manpower and material with increased efficiency and pace of construction. One of the most promising solutions for this issue suggested by the researchers is the precast construction. Precast construction entirely restructures the conventional construction process to improve the quality and pace of the construction. The predicaments with precast construction are shrinkage of filling material between the wall which leads to crack formation and also cause leakage of water. The occurrence of shrinkage is initiated and leaded by the compacting or filling problem in filling materials up to ground level due to the use of coarse aggregate and the usage of non flexible and improper bonding of sealant in the wall joints. In order to reduce these structural problems, we investigated the method of SIFCON (slurry infiltrated fibre concrete) with varies mix proportion 1: 1, 1:1.5 and 1:2 with the replacement of coarse aggregate by perlite. The sealant we used is poly sulphide sealant and the watercement ratio of the filling material varies between 0.3 and 0.4. Even though the conventional practical way of using fibres in SIFCON is limited up to 12%, we investigated the usage of fibres up to 20% in this experiment. The results obtained from the experiment shows that the filling material with the cement mortar ratio of 1:1.5 with 5% glass fibre applied in the method of Slurry Infiltrated Fibre Concrete successfully arrests the leakage of water between the wall joints.
