Abstract: We developed a new structural light weight concrete by completely replacing coarse aggregate in concrete by expanded polystyrene (EPS) beads. Expanded polystyrene (EPS) is a lightweight material that has been used in engineering applications since at least the 1950s. Expanded polystyrene waste in a granular form is used as light weight aggregate to produce light weight nonstructural concrete with the unit weight varying from 950 kg/m³ to 1350kg/m³. This paper reports the results of an experimental investigation into the engineering properties, such as compressive strength, modulus of elasticity, drying shrinkage and creep, of polystyrene aggregate concrete varying in density. Keywords: EPS beads, concrete, compression Strength, Replacement.
I. INTRODUCTION 1.1 INTRODUCTION The three basic needs of man are food, clothing and shelter. Civil Engineer has relevance with all basic needs of man directly or indirectly. Man has progressed a lot in developing the method of constructing shelter. Initially man used to stay in huts and time passed it developed into house that is load bearing. In this constructed environment, the rising cost of building construction materials is the factor of great concern. The cost of building materials are raising day by day. Nowadays most of the researchers have focus on use of the waste materials in concrete according to their properties. Fly ash, Rice husk, Slag and Sludge from the treatment of industrial and domestic waste water has been found suitable as partial replacement for cement in concrete. The EPS is a material which can be a substitute for coarse aggregate. EPS concrete has better workability because of the smooth surface on one side of the shell. The aim of this study is to investigate the effect of polystyrene aggregate size on strength and moisture migration characteristics of lightweight concrete. The present study covers the use of expanded polystyrene (EPS) and un-expanded polystyrene (UEPS) beads as lightweight aggregate in concretes that contain fly ash as a supplementary cementations material. Lightweight concrete with wide range of concrete densities (1000-1900 kg/m3) were studied mainly for compressive strength, split tensile strength, moisture migration and absorption.
II. THESIS OBJECTIVE
To find the characteristics (workability, compressive, Flexural, Tensile) of EPS M40 and M50.
To prepare lightweight concrete by using EPS as course aggregate.
To increase the speed of construction, enhance green construction environment we can use lightweight concrete. The possibility exists for the partial replacement of coarse aggregate with EPS to produce lightweight concrete. EPS exhibits more resistance against crushing, impact and abrasion, compared to crushed granite aggregate. EPS can be grouped under lightweight aggregate. There is no need to treat the EPS before use as an aggregate except for water absorption. EPS shell is compatible with the cement.
