Abstract
Indonesia is a country with relatively high earthquake activity. The selection and use of light weight building materials become very important in order to reduce building load when earthquake is occurring. There are several methods to produce lightweight concrete, including the use of lightweight aggregate like polystyrene waste. The use of concrete wall panel in houses or high-rise buildings construction aims to reduce construction cost and building time. Hence, study on the use of polystyrene for lightweight concrete wall panel with pre-compression technique would be very beneficial. This study deals with 3 specimen tests: group 1 is delaying with concrete compressive while group 2 is dealing with flexural strength and group 3 is dealing with compression strength. Group 1 consists of 3 pieces of cube specimen with dimensions of 7×7×7 cm while group 2 and 3 consist of 3 pieces of wall panel specimen with dimensions of 80×30×4 cm. The wall panel is reinforced with 2 layers of wire 0.6 mm grid 6×6 mm. In the specimens making process, a pressure of 2 MPa is applied. After 28 days, the specimens were tested by utilizing several equipment’s such as primary loading frame, load cell, hydraulic jacks, LVDT and data logger. The test shows the average compressive strength polystyrene concrete is 2.72 Mpa with average of density is 1.332 kg m–3. The elastic modulus of the polystyrene concrete is 278 MPa, the flexural strength of polystyrene concrete wall panel is 4.0423 MPa, the flexural rigidity of the polystyrene concrete wall panel is 897.37 Nmm–1 and the compressive strength of the polystyrene concrete wall panels is near to 4.1367 Mpa.
