Abstract

According to Rencana Induk Perkeretaapian Nasional (RIPNas), making  plans for the development of Indonesian railways until the next 2030. The targets for the development of railway networks and services to be achieved in 2030 include a national network of 12,100 km (spread on Java-Bali, Sumatra, Kalimantan, Sulawesi and Papua). Construction of railway track is generally divided into two main types, namely, ballasted tracks and non-ballast tracks.  In this study the non-ballasted track or ballastless track is to modify the width of the sleeper  that will be used without using ballasts on the railroad tracks. This is done to reduce the use of coarse aggregates in ballasts so that if used in areas that do not have natural resources in the form of coarse aggregates a railway track can be built. The research will be carried out according to the condition of the soil gravel, dense sand, medium dense sand, silty medium dense dan loose sand. Different types of soil cause different responses or behaviors from the modification of the sleeper  that are located above the ground. This study will discuss the analysis of rail displacement and rail bending stress that occur in the modification of railroad concrete sleeper  for non-ballast use in some soil conditions. The study was conducted with software SAP2000 version 2014 to analyze  displacement and rail bending stress on concrete sleeper modification with dimensions 400 x 2440 mm2; 1200 x 2440 mm2; 2000 x 2440 mm2; 2800 x 2440 mm2 dan 3600 x 2440 mm2 for each different type of soil to determine the dimensions of modification of concrete sleeper  that can be used. According AREMA(1999) Result of rail displacement rail may not exceed 6 mm and rail bending  stress may not exceed 75 N/mm2.

Abstract

Lightweight concrete is high in demand as it offers lighter specific gravity which makes the load on the structure smaller. In this research, lightweight concrete was produced by mixing water, cement, sand and foam. Besides aiming to obtain lighter specific gravity, the target of this research was also to design lightweight foam concrete with compressive strength equal to the one of commonly used materials for walls of around 3-5 MPa. However, foam concrete has relatively weaker tensile strength, that it would be inadequate when it has to hold the vertical force of the wall when it is applied as wall panels. This research was conducted to examine the flexural strength of the use of GRC coating and wiremesh for wall panels. Cylinder test was performed using tools with a size of 150 mm in diameter x 300 mm in length to analyze the modulus of elasticity at 28 days old, and three cubical test tools for each variance with a size of 50 mm x 50 mm x 50 were employed to test the tensile strength at 28 days old. A number of wall panel specimens with a thickness of 50 mm, width of 400 mm and length of 800 mm were used to measure the flexural strength. The tests performed in this research resulted in modulus of elasticity of 6856,6 MPa, tensile strength of 0,7 MPa. The flexural strength of wall panels without GRC outer layer and without wiremesh reinforcement was found at 1,5 MPa. Meanwhile, the flexural strength of the wall panel with GRC outer layer without wiremesh reinforcement was found at 4,6 MPa. Finally, the wall panel applied with GRC outer layer and wiremesh reinforcement showed a flexural strength 5,3 MPa.
