Abstract(s)

This internship report is about production, monitoring and performance of recycled aggregates (RA) from construction and demolition wastes (CDW). Use of RA can be useful for environmental protection and economic terms. The focus of this internship was to identify the basic properties of RA produced in the company. Natural aggregates present in the Laboratory of Institute Polytechnic of Leiria are used as reference aggregates. Similarly, the properties of RA concrete were determined and explained here. Concrete is prepared considering natural aggregate concrete as base concrete, RA of 20% and RA of 100%. Basic concrete properties like slump test, compressive strength, Ultrasonic pulse velocity test explained here for different combinations. Use of RA has been found useful for pavement construction. Reasons for use of RA in pavement construction, with experimental results are explained here in detail.
