Effects of marble rubble in interlocking paving units

الملخص EN

This study examines the effect of marble rubble, in three forms ; powder form, as aggregates ((3-8mm) and (20mm)) on the properties of manufactured interlocking paving units : Experiments were carried out to determine product compressive strength, water absorption, and abrasion resistance according to both Egyptian Standard Specifications (ESS) and American Society for Testing and Materials (ASTM) at ages 28 days and 6 months.

In addition, water absorption and indirect tensile splitting tests were carried out according to European Standard (EN) at ages 28 days and 6 months.

Results proved that marble powder enhanced compressive strength and improved abrasion resistance significantly when compared to the control mix.
