Mechanical Properties of lightweight Concrete Produced using Pottery Waste as Aggregate

Abstract

Structures built using lightweight concrete have feature of the lower own weight than that of the conventional concrete, where this property contributes to reducing the construction cost. This paper study recycling of pottery waste (PW) to use it as aggregate to develop structural lightweight concrete. To achieve this aim, six concrete mixtures were prepared. Five mixes developed using PW of 20%, 40 %, 60%, 80%, and 100% as a partially and wholly replacement of normal weight aggregate, while the control mix produced using normal weight aggregate of dolomite. The properties; consistency, dry density, water absorption, compressive, tensile and flexural strengths were studied and compared with the same properties of the control mix. Experimental results indicate that using 40, 60, 80, and 100% of PW as dolomite replacement can produce lightweight concrete, also all concrete mixtures containing PW aggregate can classified as structural concrete where their compressive strengths are more than 17 Mpa.
