Abstract

It is observed that the use of mineral additives in our country and the world are becoming increasingly widespread due to the positive effect of cement and concrete mortars on mechanical properties. In addition, it has been determined that energy resources are protected and environmental pollution is reduced thanks to the utilization of waste. In this study, the effects of rice husk ash to water demand and volume expansion, setting time, compressive strength of the blended cement were investigated. For this purpose, rice husk ash was added as a replacement for Portland cement (CEM I 42.5 R) in amounts of 0%, 2.5%, 5%, 7.5% and 10% by weight. Afterwards, mechanical, chemical and physical determinations of cement paste and mortar samples were determined by standard cement tests. The obtained data showed differences in setting time and volume expansion value that are depended on physical and chemical structure of the raw materials. Consequently, it is thought that the use of rice husk ash in the cement sector can provide economic and ecological benefits.

Özet

Ülkemizde ve dünyada mineral katkıların kullanımının, çimento ve beton harçlarının mekanik özelliklerine olumlu etkisi nedeniyle giderek yaygınlaştığı izlenmektedir. Bunun yanı sıra, atıkların değerlendirilmesi sayesinde enerji kaynaklarının korunduğu ve çevresel kirliliğin azaldığı tespit edilmiştir. Bu çalışmada, pirinç kabuğu külünün, katkılı çimentoda su ihtiyacı, hacim genleşmesi, priz süresi ve basınç dayanımı değerlerine etkileri araştırılmıştır. Bu amaçla pirinç kabuğu külünün, ağırlıkça %0, %2.5, %5, %7.5 ve %10 oranlarında Portland çimento (CEM I 42.5 R) yerine ikame edilmiştir. Daha sonra çimento hamur ve harç örneklerinin standart çimento deneyleriyle mekanik, kimyasal ve fiziksel belirlenmiştir. Elde edilen veriler, kullanılan hammaddelerin fiziksel ve kimyasal yapısına göre su ihtiyacında ve priz sürelerinde farklılıklar meydana geldiğini göstermiştir. Sonuç olarak pirinç kabuğu külünün çimento sektöründe kullanılmasıyla ekonomik ve ekolojik yarar sağlanabileceği düşünülmektedir.
