The study deals with the usage of perforated foam of various percentages to that of coarse aggregate to produce light weight concrete. With the day to day increase in industries and civilization’s expansion it has become very much necessary to produce structures with proficiently lesser weight. Its usage has become more proficient in construction of building in earthquake prone areas. This experimental investigation deals with the study of strength parameters of light weight concrete by performing various strength test and its various behavior s such as compression, tensile and flexure are studied by adding preformed foam at various proportions of 0%, 2%, 5%, 10%, 20% and 40%. All these strength parameter test are performed on 7th day, 14th day and 28th day respectively from day of casting

This paper presents the experimental and analytical evaluation of the feasibility of a proposed fiber reinforced polymer (FRP) retrofit method to strengthen corroded steel columns. This method consists of two steps: (1) wrapping the corroded steel column with an FRP jacket, and (2) filling the jacket with expansive light-weight concrete. Seven steel columns were tested in the laboratory including five strengthened columns with the proposed technique. The first two were used as control units where one was a virgin shape and the second was notched in the center zone to simulate the loss of section due to corrosion. The remaining five were all notched, and confined with FRP composite pipes within the simulated corroded zone and subsequently filled with light-weight concrete. All specimens were axially loaded to failure while strain and displacement readings were measured to demonstrate the feasibility of this repair concept. Test results show that the proposed FRP retrofit method for steel columns can be successfully applied. Furthermore, an analytical model was developed that can predict the load capacity of the FRP retrofitted steel column.
