Popis: Oil palm shell (OPS) aggregates can be used as a replacement of coarse aggregate in concrete to produce lightweight concrete. OPS is found to absorb more water compared to normal aggregate. Hence, surface treatment is carried out on OPS and the effect of water cement ratio on strength of concrete is investigated. This paper presents X-ray diffraction analysis carried out for treated and non-treated OPS (NTOPS) aggregate to find the mineralogical characteristics. Microstructural analysis and interfacial transition zone is investigated for treated and NTOPS using digital image processing or digital microscope. The results of investigation is compared with conventional concrete.
