Abstract

The environmental problems associated with cement production are based on energy consumption and resulting factory emissions. In many studies carried out in order to reduce the environmental effects of cement, it is reported that the materials used by substitution method have a positive effect on the development of strength and durability. In this context, while the amount of cement consumed decreases, on the other hand, cement-based composites with equal or superior properties can be obtained. In the study, micronized calcite was substituted into cement by weight at 0%, 3%, 5% and 10% ratios. The subsidence values of the fresh concrete obtained with calcite mineral were determined at different rates. The sedimentation values of fresh concrete obtained with calcite mineral substituted in different proportions were determined. Hardened concrete samples were subjected to water absorption, ultrasound transition speed, Schmidt hammer and compressive strength tests. As a result, it has been determined that the use of calcite up to 10% increases the compressive strength of concrete.

Özet

Çimento üretimiyle ilişkili çevre sorunlarının temelinde; enerji tüketimi ve ortaya çıkan fabrika emisyonları bulunmaktadır. Çimentonun çevresel etkilerinin azaltılması amacıyla gerçekleştirilen pek çok araştırmada ikame yöntemiyle kullanılan malzemelerin dayanım ve dayanıklılık gelişimine olumlu etkisi olduğu bildirilmektedir. Bu bağlamda, tüketilen çimento miktarı azalırken diğer taraftan eşit veya daha üstün özelliklerde çimento esaslı kompozitler elde edilebilmektedir. Çalışmada mikronize kalsit %0, %3, %5 ve %10 oranlarında ağırlıkça çimentoya ikame edilmiştir. Farklı oranlarda kalsit minerali ile elde edilen taze betonların çökme değerleri belirlenmiştir. Sertleşmiş beton numuneler ise su emme, ultrases geçiş hızı, Schmidt çekici ve basınç dayanımı deneylerine tabi tutulmuştur. Sonuç olarak kalsitin %10’a kadar kullanımının betonun basınç dayanımı arttırdığı belirlenmiştir.
