Alternatif bağlayıcı ve agrega kullanımının betonun basınç dayanımına etkisi

Öz

Endüstriyel atıkların beton üretiminde kullanımı, çevresel etkilerin azaltılması ve maliyetlerin düşürülmesi açısından büyük önem taşımaktadır. Bu çalışmada, çimento yerine olivin minerali, ince agrega olarak krom tozu ve kaba agrega olarak krom cürufu kullanılarak beton karışımları tasarlanmıştır. Farklı bağlayıcı ve agrega oranlarının, betonun basınç dayanımı üzerindeki etkileri 7 günlük kürleme süresi sonunda incelenmiştir. Deneysel sonuçlar, %5 olivin ikamesi ile yapılan karışımların, özellikle 500 kg/m³ çimento dozajına sahip karışımlarda 22.30 MPa olarak en yüksek basınç dayanımını sağladığını göstermiştir. Bu sonuç, düşük su/çimento oranı ve olivin katkısının erken yaş dayanımını artırdığına işaret etmektedir. Ayrıca su/çimento oranı 0.61 olan karışımlarda krom tozu miktarının %20'ye çıkarılması, basınç dayanımında %11.7' lik bir artışa yol açmıştır, bu da krom tozunun betonun mekanik performansını artırmada olumlu bir etkisi olduğunu göstermektedir. Bu bulgular, çimento ikameleri ve agrega türlerinin betonun mekanik özelliklerini önemli ölçüde etkileyebileceğini, dolayısıyla her iki malzeme bileşiminin dikkatlice seçilmesi gerektiğini ortaya koymaktadır.

Effects of Alternative Binder and Aggregate Use on the Compressive Strength of Concrete

Abstract

The use of industrial wastes in concrete production is of significant importance in reducing environmental impacts and lowering costs. In this study, concrete mixtures were designed by using olivine minerals as a substitute for Portland cement (PC), chromite powder as fine aggregate, and ferrochromium slag as coarse aggregate. The effects of different binder and aggregate ratios on the compressive strength of the concrete were examined after a 7-day curing period. Experimental results showed that mixtures with 5% olivine substitution achieved the highest compressive strength of 22.30 MPa, particularly in mixtures with a cement dosage of 500 kg/m³. This result indicates that the low water/cement ratio and the addition of olivine contribute to increased early-age strength. Furthermore, increasing the chromite powder content to 20% in mixtures with a water/cement ratio of 0.61 led to an 11.7% increase in compressive strength, demonstrating the positive impact of chromite powder on the mechanical performance of the concrete. These findings highlight that cement replacements and aggregate types can significantly affect the mechanical properties of concrete, emphasizing the need for careful selection of both material compositions.
