Quality of Recycled Aggregates and Compressive Strength of No-Fines Recycled-Aggregate Concrete

open access: yesEngineering, Technology & Applied Science Research, 2021
This research paper presents the laboratory investigations of the compressive strength of no-fines concrete made with demolished waste as coarse aggregates used in percentages from 20% to 100%. The basic properties of aggregates were determined. Sieve analysis of both conventional and recycled aggregates was conducted to ensure the existence of well ...
