Abstract

In this paper, the effect of pre-soaked local lightweight SCORIA FINE AGGREGATES on AUTOGENOUS SHRINKAGE, strength and TRANSPORT PROPERTIES of CEMENT MORTARs is investigated. Different CEMENT MORTARs with a constant water/cement ratio of 0.34 were prepared substituting normal fine aggregates by lightweight SCORIA FINE AGGREGATES with the same grading at five different volume fractions of 0%, 10%, 20%, 50% and 100%. AUTOGENOUS SHRINKAGE, compressive and flexural strength, workability, pulse velocity, water absorption and sorptivity (rate of water absorption), were measured in all mortars and compared with reference specimen. It has been found that incorporation of pre-soaked lightweight scoria sand in CEMENT MORTARs as INTERNAL CURING agent can successfully control the AUTOGENOUS SHRINKAGE, but effects inversely on other properties (strength and TRANSPORT PROPERTIES) of mortars that should be significantly considered. It seems that an optimum use of pre-soaked lightweight scoria sand can modify all properties of mortars and concretes.
