Mineral Katkılarla Stabilize Edilmiş Sıkıştırılmış Toprağın Uzun Vadeli Dayanımı ve Performansı Üzerine Deneysel Çalışma

İnşaat sektöründe sürdürülebilirliğin önemi ve takdiri artıyor. Konvansiyonel sıkıştırılmış toprak inşaatı, sürdürülebilirlik açısından birçok faydası olan eski bir inşaat şeklidir. Son yıllarda sıkıştırılmış toprak, diğer toprak yapı yöntemleri ile birlikte dünyanın birçok ülkesinde modern binaların yerine giderek artan bir şekilde kullanılmaktadır. Bu çalışmanın genel amacı, Öğütülmüş granül yüksek fırın cürufu gibi mineral katkı ilavesiyle sıkıştırılmış toprağın fiziksel özelliklerini, sıkıştırma özelliklerini ve performansını anlamaktır. Deneysel inceleme yapıldı ve basınç dayanımı ve Başlangıç Teğet Modülü belirlendi. Öğütülmüş Yüksek Fırın Cürufunun (GGBS) stabilize sıkıştırılmış toprağın uzun vadeli etkisi üzerindeki etkisini incelemek için performans testi yapıldı. Zeminin kil içeriğindeki azalma, ıslak basınç dayanımının ve başlangıç teğet modülünün artmasıyla sonuçlanmıştır. Daha düşük kil içeriğine ve daha yüksek GGBS içeriğine sahip karışımda gelişmiş performans özellikleri ve mukavemette iyileşme gözlemlendi. Bunun nedeni, eklenen mineral katkı GGBS'den genişleyen kil parçacıklarının yüzey alanının kapsanmasındaki iyileşme olabilir.

Experimental Study on Long-Term Strength and Performance of Rammed Earth Stabilized with Mineral Admixtures

The significance and appreciation for sustainability is rising within the construction industry. Conventional rammed earth construction is an ancient form of construction that has many benefits in terms of sustainability. Rammed earth in current years, together with other earth building methods, has been increasingly used in place of modern buildings in many countries around the world. The overall target of this study is to understand the physical properties, compaction characteristics and performance of rammed earth with the addition of mineral admixture like Ground granulated blast furnace slag. The experimental investigation was carried out and the compressive strength, and Initial Tangent Modulus was determined. Performance test was carried out to study the effect Ground Granulated Blast Furnace Slag (GGBS) on the long-term effect of stabilized rammed earth. Reduction in clay content of the soil resulted in increase of wet compressive strength and the initial tangent modulus. Enhanced performance characteristics and improvement in strength was observed in the mix with lower clay content and higher GGBS content. This may be due to the reason of improvement in coverage of surface area of expansive clay particles from the added mineral admixture GGBS.
