Abstract: In this paper, a new type of GFRP shear reinforcement is proposed for reinforced concrete beams. The new GFRP shear reinforcement is manufactured into a plate shape with several openings to ensure high adhesion property with the concrete. The test was performed on six concrete beam specimens with shear span-to-depth ratio of 2.4 to experimentally investigate the performance of the proposed shear reinforcement. Test parameters include the shape of GFRP shear reinforcement and the amount of the GFRP reinforcement. We examined the effects of these parameters on the shear strength of the GFRP plate shear reinforced concrete beam.A shear strength equation for concrete beams with the proposed GFRP shear reinforcement is proposed based on modifying the existing shear strength equation for concrete beams with steel stirrups in ACI 318-11. Comparing the test results with the estimations based on the proposed equation, the results generally shows good agreement. Results from this paper show that

Abstract: Construction and demolition waste results from the construction, renovation and demolition of manmade structures. The types of materials found in construction and demolition waste include not only the elements used as primary building materials but also various secondary materials such as paints, sealants, adhesives etc. including the packaging materials. The unscientific management of construction and demolition waste such as land fillings may have the ill impact on quality of groundwater due to leaching of rainwater through landfills. The recycle and reuse, which is common practice in management of solid waste, has entered in the field of construction and demolition waste too. It is estimated that the construction industry in India generates about 10-12 million tons of waste annually. The projections for building material requirement ofthe housing sector indicate a shortage of aggregates to the extent of about 55,000 million cu.m. The recycling and reusing of aggregate material from
