Flexure strength measurement for cement replacement with recycled glass

ABSTRACT The most important environmental Impediments at the present time is the accumulation of glass waste (transparent glass bottles) many experiments and researches have been made on waste and recycling to get use of it as much as possible. this research study recycling of colorless glass waste and turn them into raw materials alternative for cement to save the environment from glass waste and reduce some of the disadvantages of cement and its interactions with conserving the mechanical and physical properties of concrete.This research include recycling of colorless glass bottle which is locally used and turn them into a fine powder to be replaced by a certain percentages of cement. A set of required samples were prepared for mechanical tests at a rate of ten samples for different weight percentage which is (2% ,4% ,5% ,6% ,8% ,10% ,15% ,20% ,25%) . Three point bending was measured to American standard for calibration (ASTM C133-97) to measure the results showed that the highest Maximum applied of rupture is at the low ratios 2% ,4% ,5% which is (280.52, 233.49, 277.20) KN respectively for indigenous mix recorded bending resistance (272.60) KN.
