Increase in vehicular traffic and changing environmental; will reduce the service life of concrete surfaces. Repair and maintenance of concrete pavement and floors is a routine practice in India to enhance the serviceability. Abrasion is contributing in lowering the service age of concrete. Many structures such as dams, canals, industrial floors and roads are required to have sufficient abrasion resistance. Abrasion resistance is a property of harden concrete surface to be worn away by abrasive forces. Highly abrasion resistance concrete surfaces are preferred in industry floor and in construction of roads. Aggregates play an important role in strength characteristics of concrete; strength has a decisive influence on abrasion resistance of concrete. This paper presents an overview of some of the research published regarding abrasion testing and effect of concrete properties and ingredients of concrete on abrasion resistance. Studies show that this is promising future for the abrasion resistance of a concrete used in road pavement, industrial floors, dams etc. to assess the serviceability. It was notices from literature that abrasion properties are varying with aggregate type, compressive strength, cement content, W/c ratio, curing and show drastic changes when concrete added with silica fumes, fly ash, fibers and latex. Age of the concrete and type of loading for which concrete surface is exposed play vital role in abrasion. This study culminates to explore abrasion resistance property on assorted mix design, high density concrete and age of concrete. |
