摘要

油棕壳(OPS)骨料可替代混凝土中的粗骨料生产轻质混凝土。发现OPS比普通骨料吸收更多的水。为此，对OPS进行了表面处理，并研究了水灰比对混凝土强度的影响。本文对处理后和未处理的OPS (NTOPS)骨料进行了x射线衍射分析，找出了矿物学特征。利用数字图像处理或数码显微镜对处理后和NTOPS的微观结构和界面过渡区进行了研究。研究结果与常规混凝土进行了比较。

Micro-structural and Interfacial Transition Zone investigation on Oil Palm Shell lightweight concrete.

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.

期刊介绍： IJMMP publishes contributions on mechanical, electrical, magnetic and optical properties of metal, ceramic and polymeric materials in terms of the crystal structure and microstructure. Papers treat all aspects of materials, i.e., their selection, characterisation, transformation, modification, testing, and evaluation in the decision-making phase of product design/manufacture. Contributions in the fields of product, design and improvement of material properties in various production processes are welcome, along with scientific papers on new technologies, processes and materials, and on the modelling of processes.
