ABRASION RESISTANCE ESTIMATION OF HIGH STRENGTH CONCRETE

Abstract

This study gives the results of a laboratory investigation undertaken to determine the relationship between mechanical properties (compressive and flexural strengths) and abrasion resistance of 65-85 MPa high strength concretes incorporating silica fume, fly ash and silica fume-fly ash mixtures as supplementary cementing materials. A series of six different concrete mixtures including a control high strength concrete mixture (C1), and five high strength concrete mixtures (C2, C3, C4, C5, C6) incorporating supplementary cementing materials, were manufactured. The compressive strength, flexural strength, and abrasion resistance were determined for each mixture at 28-days. Mathematical expressions were suggested to estimate the abrasion resistance of concrete regarding their compressive strength and flexural strength.
