Abstract

The durability of a concrete road to abrasive forces can be assessed effectively by measuring its abrasion resistance. This technical note reports the findings of a laboratory study including compressive strength, abrasion, and porosity properties of concrete mixtures made with fly ash and normal portland cement. The study involves two replacement ratios of fly ash, various water-cement ratios, the use of a superplasticizer, two curing conditions, and four concrete ages. Statistical models that relate abrasion to strength and porosity are presented.
