Abstract

This research was conducted to know the failure behavior and flexural strength of reinforced concrete (R/C) beam strengthened with GFRP sheet. The research used simple supported beams with dimension of 100x150x1100 mm. The beam resisted two concentrated loads at a distance of 300 mm from each support. On the beams were applied 3 conditions that were beam without addition of GFRP sheet; beam with addition of 1 layer GFRP sheet and beam with addition of 2 layers GFRP sheet. The GFRP sheets used in this research were made of woven roving glass fibre mixed with epoxy resin. The data collected in this research were crack load, ultimate load, crack pattern, crack width, deflection and failure behavior. Results of from this research indicated that addition of GFRP sheet decreased the length and width of the R/C beam crack. The addition of GFRP sheet improved flexural strength of R/C beam as well. The addition of 1 layer GFRP sheet increased the flexural strength by 10,8 %, with failure in flexure accompanied by breaking of the sheet. On the other hand, the addition of 2 layers GFRP sheet increased the flexural strength by 13,4 %, with failure in flexure accompanied by debonding of the sheet from concrete surface. This showed that the sheet did not work effectively.

Abstract

he aim of this research was to obtain the benefits of Lapindo silt as cement substitution material in fabricating paving block with the most ideal mixture composition evaluated from compressive strength and water absorption with physical quality based on PUBI-1986. Paving block were made using Lapindo silt as cement substitution with composition that were A mixture (100% PC; 0% LS), B mixture (90% PC; 10% LS), C mixture (80% PC; 20% LS), D mixture (70% PC; 30% LS), and E mixture (60% PC; 40% LS). Fabricating process of paving block started from material preparation, making mixture, molding, curing, selection, and then followed by conducting the research by compressing the paving block and obtaining the water absorption. Based from water absorption, result of this research showed that the mix D has better benefits of Lapindo silt as cement substitution material with optimum water absorption and decreasing compressive strength. This was caused by SiO2 contained in the mixture (as filler) and also supported by CaO (as a binder between materials). The small value of water absorption can also increase the durability of paving block. The best composition was D mixture, where has optimum water absorption with little decreasing in value of compressive strength.
