Some Properties of Concrete Containing Aluminum

Abstract

This paper presents the results of investigation conducted to evaluate the properties of concrete containing aluminum Roofing Sheet Waste as partial replacement of cement by weight. The properties investigated included the setting times of cement-ARSW paste, workability, density, compressive strength using 168 numbers of 150 x 150 x 150 mm cube specimens. The chemical compositions and pozzolanic properties were also investigated. The results showed that: (I.) the chemical composition of aluminum Roofing Sheet Waste (ARSW) is suitable for concrete production, (ii.) ARSW has pozzolanic characteristic, (iii.) the concrete produced with ARSW resulted in concrete whose densities are within the range for normal weight concrete, and (iv.) using ARSW to replace cement up to 10% will not affect the compressive strength of the concrete significantly. From these results, it can be concluded that Roofing Sheet Waste is suitable for concrete production, and thus can be used as a mean to remove the potentially harmful waste that ARSW constitutes.
