Publication Date : 30/10/2022
Concrete is one of the most widely used construction materials in the world. To ensure sustainability and a reduction in the cost of concrete, the use of renewable agricultural waste materials and plastic materials as aggregates becomes desirable. This paper presents results of a comparative study of the physical and compressive strength of palm kernel shell concrete (PKS) plastic waste(PT) and normal weight concrete (NWC) using Ordinary Portland Cement (OPC) herein called Lafarge Cement(class 42.5N). Palm kernel shells were used as lightweight coarse aggregate in PKS, plastic materials was use as aggregate in plastic waste and granite was used as aggregates for the normal concrete. The study was conducted in accordance with the British Standards (BS 812, 1990; BS 1881, 1996). Three mixes of ratios 1:2:4 ,1:3:3, 1:4 by weight were used in the study. The values obtained for water absorption, aggregate impact, aggregate crushing, specific gravity and Los Angeles abrasion, satisfy the minimum requirements of aggregates for structural concrete as specified in BS 882, 1992. Compressive strengths of both PKS, plastics and normal weight concretes with Lafarge cement evaluated at 7, 14 and 28-days showed that Lafarge cement produced concretes of higher compressive strengths for PKS, plastics and normal weight concrete. In general, the compressive strength of PKS using Lafarge cement compare well with those obtained from other materials used for structural lightweight concretes.
