“…Optimum values of maximum deflection, peak load, and flexural strength, achieved by series II of the specimens. This finding confirms the study [15] of that concrete sandwich beam (2.5 m x 20 cm x 20 mm) containing EPS (and also Textile Reinforced Cementitious Composites, TRCs) can have maximum deflection about 45 mm and peak load about 5 kN.Hence, the optimum length of EPS concrete sandwich beam is 100 mm, which can be implemented to field application. .…”

Expanded Polystyrene (EPS) concrete sandwich structure has been developed and investigated since few years ago. It has advantage of high heat resistance, impact, acoustic and vibration absorption, and easy to built. However, it is important to make benchmarking of the local product of (EPS) concrete sandwich structure and the global product. Therefore, this research aims to investigate the flexural deformation of local product of EPS concrete sandwich beams such as its deflection, peak load, and flexural strength. There are 9 EPS concrete sandwich beams were tested for flexural strength with dimension of L x 200 x 7.5 mm, where L were three specific lengths of 50, 100, and 100 mm. The flexural test carried out by Universal Testing Machine, LVDT, and data logger. The experiment has shown that Optimum values of maximum deflection, peak load, and flexural strength, achieved by series II of the specimens. There was a "jigsaw phenomenon" during the loading of series II and III. Optimum values of EPS concrete sandwich beam achieved by series II with length of 100 mm. It has peak load of 4.39 kN, flexural strength of 3.42 MPa and maximum deflection of 2.47 mm. The research found that the local product of EPS concrete sandwich beam used as specimens in this research complies with the previous investigation and application.
