Effect of plastering and Carbon Fibre Reinforced Polymer (CFRP) on concrete masonry prism strength capacity

Effect of plastering and Carbon Fibre Reinforced Polymer (CFRP) on concrete masonry prism strength capacity / Mohd Anuar Mohd Yusof
Batu bata merupakan bahan penting dalam pembinaan khususnya pembinaan bangunan dan ianya digunakan secara meluas di segenap pelusuk dunia sejak beberapa abad yang lalu sehingga ke hari ini. Penggunaan bahan ini berkait rapat dengan beberapa faktor antaranya ialah disebabkan kerana mudah diperolehi, harga yang murah dan pengendalian kerja yang mudah. Namun, terdapat masalah yang timbul, kesan daripada penggunaan batu bata tersebut antaranya ialah keretakan pada dinding bangunan. Bagi tujuan kajian, sejumlah 12 unit spesimen di bina, dengan menggunakan batu batu blok berdimensi 390 mm x 190 mm x 190 mm seunit dan diikat secara menegak sehingga mencapai tinggi 1 meter termasuk ketebalan mortar, terbahagi kepada empat kumpulan yang berbeza, iaitu tanpa lepaan (A), satu belah bahagian di lepa (B), kedua belah bahagian dilepa (C) dan kedua belah bahagian dilekatkan dengan polimer karbon gentian diperkuatkan secara menegak (D), dimana setiap kumpulan berkuantiti 3 unit. Nisbah bancuhan bahan yang digunakan untuk penghasilan mortar adalah berdasarkan ASTM C 1437 bagi setiap spesimen yang dihasilkan. Hasil pemerhatian dan ujian didapati nilai purata bagi beban gagal adalah seperti berikut (A) 180 kN , (B) 175 kN, (C) 209 kN, dan (D) 198 kN. Kesimpulan dapat dibuat kekuatan kumpulan (C) adalah yang tertinggi namun corak keretakkan tidak dapat dikawal berbanding kumpulan (D) dimana corak keretakkan adalah secara pugak serta dapat dijangkakan _______________________________________________________________________________________________________ Brick is an important material in the construction of particular buildings and it is widely used in all parts of the world over the last century until today. The use of these materials is closely related to several factors, among which are easily obtained, cheap and easy job control. There are some effects that arise through the use of brick in building construction. For the purposes of the study, a total of 12 units of bond brick for prism in architecture, using concrete blocks of dimensions 390 mm x 190 mm x 190 mm unit and each specimen that is built has a height of 1 metre, the specimens are classified into controlled specimen without any plaster, one sided plastered, two sided plastered, and specimen strengthened by Carbon Fibre Reinforced Polymer (CFRP) strip in vertical orientation. The mixing ratio of the materials used for the production of mortar for the use of bonding and rendering are the same and tests conducted in accordance with ASTM C 1437 to ensure that the characteristics of the were resulting set is the same and controlled. During the tests performed, the effects of the resulting pressure is observed and recorded. The results of observations and tests found the average value of the failure load is as follows (A) 180 kN, (B) 175 kN, (C) 209 kN, and (D) 198 kN. The conclusion that can be made is strength group (C) is the highest but crack pattern could be controlled compared to the group (D) in which the pattern of cracks is vertical and can be expected.
