Özet:
Every year, approximately 1.5 billion tires are getting discarded. This number is
expected to reach ~5 billion by 2030. Tire landfills create a significant fire hazard
and not an ideal solution. Hence, disposal of waste tires is prohibited in many
countries; instead, they should be recovered and recycled. This thesis aims to
produce pervious concrete – a special concrete with high porosity that allows water
to pass directly through, hence reducing the surface runoff and allowing groundwater
recharging – utilizing scrap tires as aggregates. The main weaknesses of concretes
using scrap tires as aggregates (rubberized concretes) stem from poor adhesion
between cement and rubber and the soft and weak nature of rubber aggregate. In this
thesis, main aim was developing more sustainable pervious concretes for to be used
in the industry. Portion of the cement replaced with fly ash and silica fume in order
to decrease total carbon emission of the mix. And, depleting raw natural coarse
aggregates replaced with shredded rubbers. Results show that incorporation of
shredded rubber aggregates decreases mechanical strength and permeability but
increases abrasion resistance. Surface treatment with silane can improve the
mechanical strength and abrasion resistance furthermore. Yet, increased strengths
were lower than concretes with natural aggregates.
