Abstract

Düşük
yoğunluk değerine, yüksek ısı ve korozyon direncine sahip olan polipropilen
gittikçe yapı malzemeleri sektörü için daha cazip hale gelmektedir.  Bununla birlikte polipropilenin tek başına
kullanımı yapı malzemesinin mekanik dayanımını düşürmesi bakımından bazı
dezavantajlar içerir. Polipropilenin yapı malzemeleri içerisindeki uygulamalarında
bu dezavantajın ortadan kaldırılması için polipropilen kompozitleri tercih
edilmektedir. Bu çalışmada, CaCO₃ takviyeli polipropilen içeren
betonun tanımlanan kalite ölçütleri sırası ile termal iletkenlik, elektrik
direnci, 3, 7, 28 gün basınç dayanımları, 28 günlük yarmada çekme dayanımı ve
su emme oranı olarak belirlenmiştir. Deneylerde ince agrega yerine %0, %10,
%20, %30 ve %40 oranlarında CaCO₃ takviyeli polipropilen
kullanılmıştır. Dolgulu CaCO₃/PP takviyeli beton özellikleri kontrol
betonu ile kıyaslandığında %34.5 daha düşük 28 günlük basınç dayanımına, %24.7
oranında daha düşük termal iletkenliğe, %50.7 daha yüksek elektrik direncine
sahiptir.

Examination of the effects of CaCO3 reinforced and unreinforced polypropylenes which is substituted with a fine aggregate on traditional concrete properties

Abstract

Polypropylene
with low density and high heat, corrosion resistance is becoming increasingly
more attractive for the building materials sector. However, the use of
polypropylene alone has some disadvantages in terms of reducing the mechanical
strength of the building material. Polypropylene composites are preferred in
order to eliminate this disadvantage in polypropylene construction materials
applications. In this study, the thermal conductivity, electrical resistance,
3, 7, 28-day compressive strength, 28-day tensile strength and water absorption
ratio of concrete containing CaCO₃-reinforced polypropylene were
determined as quality criteria. In the experiments, 0%, 10%, 20%, 30% and 40%
of CaCO₃ reinforced polypropylene was used instead of fine
aggregate. The reinforced concrete properties of filled CaCO₃/PP
have a 28 day compressive strength of 34.5% lower than that of the control
concrete, 24.7% lower thermal conductivity and 50.7% higher electrical
resistance.
