Effect of coated expanded polystyrene (ceps) beads aggregates on the properties of hollow concrete block / Nurulfatin Aqilah Mohd Yazid
Industri pembinaan kian makmur, sentiasa berkembang dan dijangka mendominasi keseluruhan ekonomi dunia. Tidak disangkal lagi, permintaan bahan pembinaan akan meningkat. Oleh disebabkan permintaan bahan sumber yang semakin meningkat, inovasi baru ataupun alternatif diperlukan untuk mennyelesaikan permintaan tinggi untuk kerja-kerja pembinaan pada masa akan datang. Oleh yang demikian, pengunaan bahan pembinaan semulajadi tidak lagi relevan dan bahan yang boleh diperbaharui ataupun bahan buangan seperti polistirena patut dipilih sebagai alternatif. Polistirena adalah bahan plastik yang versatil, digunakan untuk pelbagai kegunaan di seluruh dunia. Walau bagaimanapun, bahan ini tidak boleh dibiodegradasi, jadi ianya perlu dikitar semula untuk kesejahteraan persekitaran masa akan datang. Polistirena bermanfaat untuk digunakan sebagai alternatif dalam industri pembinaan disebabkan oleh sifat penebat haba dan bunyi dan ringan mereka. Dalam kajian ini. ‘Expanded Polystyrene’ (EPS) yang bersalut telah digunakan sebagai pengganti aggregat halus (separuh) di dalam konkrit blok berlubang. Salutan pada EPS tersebut meningkatkan ikatan antara campuran simen dengan EPS. Konkrit blok berlubang disediakan dengan campuran mortar kering menggunakan mesin pemampat hidraulik.beberepa ujian seperti kekuatan mampatan, penyerapan air, ketumpatan dan kadar serap permulaan dijalankan untuk mengetahui ciri-ciri blok konkrit. Perbandingan antara konkrit blok dengan CEPS dan konkrit blok biasa telah dibuat. Konkrit blok CEPS mempunyai ketumpatan yang lebih rendah, kekuatan mampatan yang lebih rendah dan kadar penyerapan air yang lebih tinggi berbanding konkrit blok biasa. Oleh itu, konkrit blok CEPS sesuai digunakan untuk pembinaan ringan dan untuk kegunaan yang bukan menahan beban. Bahan tambah dan reka bentuk bancuhan yang lain perlu digunakan sekiranya ingin menggunakan blok ini sebagai unit penahan beban. _______________________________________________________________________________________________________ The construction industry is prospering and expected to continue growing and expected to dominate the overall world economy. Indeed, the construction materials demand will increase undoubtedly. Due to the increasing demand of the resources, brand new innovation or alternatives is needed to overcome the high demand of the construction activities in the future. Therefore the usage of natural materials for construction materials no longer relevant and renewable or waste materials such as polystyrene should be chosen as an alternative. Polystyrene is a versatile plastic materials that is widely used for variety of applications around the world. However, this materials is non bio-degradable so it needs to be recycled in order to have sustainable environment. Polystyrene is advantageous to be used as an alternative in construction industry because of their thermal and sound insulation properties and also their lightweight characteristic. In this study, coated expanded polystyrene (EPS) have been used as partial replacement of fine aggregates in the hollow concrete block. The coating of the EPS help to increase the bond between cement paste and EPS. The hollow concrete block samples are prepared with dry mortar mixture with hydraulic compression machine. Several tests incudes compressive strength, water absorption, density, and initial rate of suction have been conducted to know their properties. Comparison of the properties of samples with and without CEPS have been made. CEPS block samples show less density, more water absorption and lower strength compared to the conventional block samples. Therefore, CEPS block are suitable to be used for lightweight construction and non-load bearing application. If they were to be used as load bearing unit, admixtures and different mix design need to be used to achieve better properties.
