Recycled Aggregates With Fibers in Concrete Structure and Components

This project aims to develop the best economic solution by use of recycled aggregates with fibers in structural concrete to reduce the environmental impact.Therefore, the objective of this project is to investigate the hardness properties of Recycled aggregate with fibers including slump, density, compressive strength, tensile strength, modulus of elasticity and drying shrinkage.This is also to determine the durability and permeability, quality and cleanliness that are suitable for application in high strength concrete up to 60MPa compared with 100% natural aggregate.To determining the above properties of the recycled aggregate concrete with fibers by studying the influence of 100 percent recycled aggregate in concrete.The Laboratory trials were conducted to investigate the possibility of using 100 percent of recycled aggregate (20mm, 14mm and 10mm) with 25 percent of fly ash (low volume of 20% fly ash is minimum requirement by Main Roads specifications) to replace part of the cement in concrete, compared with natural aggregate.The project has also researched the costs for what is the most economical solution to making recycled aggregate with fibre concrete for high quality concrete.
