Abstract

   In this
study, the effect of macro synthetic fibre on the optimum water content and the
mechanical properties of roller compacted concrete (RCC) was investigated. A total
number of sixteen RCC mixtures were produced with four different water content
variation and four volumetric fibre levels of 0%, 0.2%, 0.4%, 0.6%. Soil
compaction method was utilised to quantify the optimum water content against
the maximum dry unit weight value for each RCC mixtures. Four different RCC
mixes of which consistency was evaluated through the modified Vebe test were
also produced according to the optimum water content identified. The
compressive and splitting tensile strength tests of RCC were conducted in order
to examine the effectiveness of fibre amount on the mechanical properties of
RCC. The test results reveal that the required water for the adequate compactibility
of fibre reinforced RCC increases with the incorporated amount of fibre. This paper
underlines that the amount of fibre is not significantly effective on the
compressive strength values whereas the maximum tensile strength is observed
for 0.4% fibre reinforced RCC.

SİLİNDİRLE SIKIŞTIRILMIŞ BETONDA MAKRO SENTETİK ELYAF KULLANIMININ OPTİMUM SU İÇERİĞİNE VE BETONUN DAYANIM ÖZELLİKLERİNE ETKİSİ

Abstract

   Bu çalışmada,
makro sentetik elyaf miktarının silindirle sıkıştırılmış betonun (SSB) optimum
su içeriğine ve mekanik özelliklerine etkisi araştırılmıştır. Makro sentetik
elyaf beton hacminin %0, %0.2, %0.4 ve %0.6 oranlarında kullanılmış olup her
bir karışım dört farklı su içeriğine sahip olacak şekilde toplam on altı SSB
karışımı üretilmiştir. Zemin sıkıştırma yöntemi kullanılarak her bir elyaf
oranı için SSB’nin maksimum kuru birim ağırlığına karşılık gelen optimum su
içeriği belirlenmiştir. Ayrıca, belirlenen optimum su içeriği kullanılarak 4
farklı SSB karışımı daha üretilmiş olup bu karışımların kıvamını belirlemek
için modifiye Vebe deneyi yapılmıştır. Elyaf miktarının SSB’nin mekanik
özellikleri üzerindeki etkisini incelemek için basınç dayanımı ve yarmada çekme
dayanımı deneyi yapılmıştır. Deneysel çalışmanın sonunda, SSB’de makro sentetik
elyaf kullanımının karışımın su ihtiyacını arttırdığı görülmüştür. Ayrıca makro
sentetik elyaf miktarındaki artışın SSB karışımların basınç dayanımını önemli
ölçüde etkilemediği ve %0.4 makro sentetik elyaf kullanımının SSB’nin yarmada
çekme dayanımında önemli ölçüde artış sağladığı sonucuna varılmıştır.
