Sensor-based monitoring of hydration and water behavior in cemented paste backfill with superplasticizer

Abstract

This study aims to evaluate the effects of superplasticizer admixture on cemented paste backfill (CPB) using sensor-assisted monitoring techniques. In the experimental work, the development of hydration, water content, negative pore water pressure, and uniaxial compressive strength was investigated in CPB samples prepared with a polycarboxylate-based high-performance superplasticiser (YPSA) at dosages of 1%, 3.5%, and 6%. For the monitoring tests, the focus was on the control sample without admixture and the sample containing 6% admixture, and their time-dependent changes were evaluated in detail. The results showed that the YPSA admixture contributed to the formation of a denser microstructure by reducing the water/cement ratio (w/c), thereby creating significant effects on electrical conductivity, volumetric water content, and negative pore water pressure. Specifically, the 6% admixture dosage provided a significant increase in early and late-age strengths, offering the potential to accelerate the production cycle and increase efficiency in underground mining. The findings reveal that the YPSA admixture not only improves workability but also enhances the hydration process and mechanical performance, making it a promising approach for optimizing the durability and performance of cementitious backfill systems.

Süperakışkanlaştırıcı katkılı çimentolu macun dolgularda sensör tabanlı hidratasyon ve su davranışı izlemesi

Öz

Bu çalışma, süperakışkanlaştırıcı katkı maddesinin çimentolu macun dolgu (ÇMD) üzerindeki etkilerini sensör destekli izleme teknikleriyle değerlendirmeyi amaçlamaktadır. Deneysel çalışmada, polikarboksilat esaslı yüksek performanslı süperakışkanlaştırıcı (YPSA) katkı, %1, %3,5 ve %6 oranlarında kullanılarak hazırlanan ÇMD numunelerinde hidratasyon, su içeriği, negatif boşluk suyu basıncı ve basınç dayanımı gelişimi incelenmiştir. İzleme testlerinde, katkısız kontrol numunesi ile %6 katkı içeren numuneye odaklanılmış ve zamana bağlı değişimler detaylı olarak değerlendirilmiştir. Sonuçlar, YPSA katkısının su/çimento (s/ç) oranını azaltarak daha yoğun bir mikroyapı oluşumuna katkıda bulunduğunu; bu sayede elektriksel iletkenlik, hacimsel su içeriği ve negatif boşluk suyu basıncı üzerinde belirgin etkiler yarattığını göstermiştir. Özellikle %6 katkı oranı, erken ve geç yaş dayanımlarında anlamlı artış sağlamış; üretim döngüsünü hızlandırma ve yeraltı madenciliğinde verimliliği artırma potansiyeli sunmuştur. Elde edilen bulgular, YPSA katkısının yalnızca işlenebilirliği değil, aynı zamanda hidratasyon sürecini ve mekanik performansı iyileştirerek sürdürülebilir dolgu uygulamaları açısından önemli avantajlar sağladığını ortaya koymaktadır.
