54Investigating the effect of expandable polystyrene beads recycled rubber powder and silica fume on compressive strength and water absorption behavior of structural and non structural lightweight concrete use in water application Karim Kazemi ok polyeng@yahoo com Date of Submission 2014 08 19 Department of Chemical Engineering Isfahan University of Technology Isfahan 84156 83111 IranDegree M Sc Language FarsiSupervisor Saeid Nouri Khorasani saeid@cc iut ac ir Behrooz Koosha cgkoosha@cc iut ac irAbstract The effect of expandable polystyrene EPS beads size and amount of recycled rubber powder and silicafume SF on compressive strength and water absorption of light concrete was investigated Addition of 10 SF wt of cement increased the compressive strength of concrete by 15 The compressive strengthincreased by 5 and 15 with addition of 10 and 20 wt of total aggregate recycled rubber powder tothe concrete respectively Presence of 5 and 15 vol of total aggregate of EPS beads with diameter of1 3 mm decreased the compressive strength by 10 and 30 respectively While adding the same amount ofEPS beads with diameter of 3 6 mm reduced the property by 17 and 37 respectively Addition of 10 SFdecreased the water absorption of concrete by 15 The water absorption decreased by 6 and 8 withaddition of 5 and 15 GRT to the concrete respectively Concrete water absorption was reduced by 8 and25 with adding 5 and 15 of EPS beads with a diameter of 1 3 mm Increasing the diameter of EPS beadsreduced the concrete water absorption Keywords Expandable polystyrene beads Recycled rubber powder Fumed silica Compressive strength Waterabsorption Concrete
