Abstract
The ability of concrete to give a lower weight and retain good properties for strength is very important concrete structures. Lightweight concrete is known for its brittleness hence the strengthening of the concrete with dispersed chopped fiber is necessary. The addition of dispersed chopped fiber in polystyrene concrete to check the effect of the fiber this concrete the main objective of this paper. The experimental method of research was used in this research paper after a proper review of previous works by other researchers were done. 42 grams of fiber were added in the concrete mix of each composition. The results of this research show a noticeable effect of fiber in the lightweight expanded polystyrene concrete. The concrete without fiber showed the best compressive strength followed by the concrete with dispersed polypropylene fiber.
Highlights
For more than fifty years, there have been attempts to overcome the drawbacks of concrete
A total of 6 lightweight expanded polystyrene concrete mix are made for the work. 9 concrete cubes were made from each mix
On the 48th hour, the Lightweight concretes (LWC) cubes were removed from the molds and kept in the curing cupboard till the 28th day the cubes were tested for compressive strength on a Matest Universal Testing Maching
Summary
For more than fifty years, there have been attempts to overcome the drawbacks of concrete. Concrete is a structural material with properties like very heavy, rigid and its thermal and acoustical qualities are not very high. Concrete is known as the most used material in the construction industry, and it is a huge consumer of natural resources. Concrete mix containing waste materials are beneficial in protecting the environment [2,3,4]. Waste materials such as polystyrene, cork, tire, are mostly used as components of building materials because the properties they possess like the thermal and acoustical properties [5,6,7,8]. Studies involving concrete-related topics approach different types of building materials with polystyrene granule, such as mortar, concrete, pavement, etc. Effects of polystyrene granule in concrete depend on its type (cement-based concrete or polymer-based concrete), dosage and type of polystyrene, etc
