Even there are any compressive strength reductions of compared to its natural, the utilization of RAC (recycled aggregate concrete) has a good result to convert CDW (construction demolition waste) become beneficial things. Due to the significant RAC lack strength and the lavish of unrecyled glass craps, and has been proposed. A more environmental friendly hybrid concrete of RAC and its reinforcement using glass pieces, cullet or waste - have higher strength than RAC itself - called GLARC (Glass Reinforced Concrete) has been proposed. A tensile testing data are needed in the assessment of the mechanical properties over the actual measurement of the flexural behavior of GLARC system. A direct tensile testing was carried out in coupon specimen forms using H011N tensile/compression equipment. Almost all of the specimens show a brittle failure. Several of them still suffers a local punching even a grip tool was applied. Tensile strength average of glass is 21.12 MPa much better than concrete tensile strength that was relatively low, around 10-15% of its compressive strength or 3 to 5√fc', thus give value around 2-5 MPa. It can be concluded that glass cullet and pieces was be able used to reinforce both NAC (natural aggregate concrete), concrete with natural aggregate and RAC, recycled concrete aggregate in order to reduce and manage unrecycled glass waste. Finally, it can be predicted initially that flexural strength of GLARC-beam structures that contain glass strips reinforcement will be increased and hence a new GLARC-beam structures has been proposed. The tensile results then used to evaluate the initial bending response and predict the flexural strength capacity in the GLARC-beam later. � 2006-2016 Asian Research Publishing Network (ARPN).
