Abstract

The objective of the present work is to predict the compressive strength, water permeability, chloride penetrability and porosity of concretes containing volcanic scoria as cement replacement after 2, 7, 28, 90 and 180 days curing. Concrete specimens have been produced with three different water-binder ratios of 0.5, 0.6 & 0.7 and replacement levels ranging from 10 to 35%. Test results revealed that curing time, the scoria content and the water-binder ratio had a large influence on all the examined properties of scoria-based concrete. An estimation equation has been developed by the authors to predict the studied properties depending on the water-binder ratio, the curing time and the replacement level of volcanic scoria. SEM/EDX analysis has been reported, as well.
