Abstract

In this study, 13 different self-compacting lightweight concrete specimens with pumice aggregate was produced with fly ash, silica fume, perlite powder and pumice powder as mineral admixtures. Mineral admixtures such that silica fume, fly ash, pumice powder and pumice powder were tried single, double and triple combinations. Control specimens was prepared with viscosity modifiers chemical additive. Compacting ability and freezing-thawing performance of all mixtures were investigated. Fresh unit weight of prepared mixture was 1900-2000 g/dm3. All of the series have been self-compatibility properties. The results showed that workability of hybrid mineral admixture was better than single using or without mineral admixtures. The compressive strength of self-compacting lightweight concretes with mineral admixtures was decreased after that freezing and thawing cycles.

Abstract

Bu çalışmada, mineral katkı olarak uçucu kül, silis dumanı, toz perlit ve pomza tozu olmak üzere 4 farklı mineral katkının kullanıldığı 13 farklı pomza agregalı kendiliğinden yerleşen hafif beton (KYHB) üretilmiştir. Uçucu kül ve silis dumanının tekli kullanıldığı karışımlardan farklı olarak ikili ve üçlü kombinasyonla da denenmiştir. Üretilen bu karışımların kendiliğinden yerleşe bilirlikleri ile donma çözülme dirençleri incelenmiş ve bu özellikler, viskosite arttırıcı kimyasal katkı ile üretilen KYHB ile kıyaslanmıştır. Deney öncesi ve sonrasında numunelerin ultra ses hızları ölçülerek dinamik elastisite modülleri hesaplanmış ve aynı numuneler üzerinde basınç dayanımı deneyleri yapılmıştır. Hazırlanan karışımların taze beton birim hacim ağırlıkları 1900-2000 g/dm3 arasında değişmiştir. Tüm seriler kendiliğinden yerleşe bilirlik kriterlerini sağlamıştır. Elde edilen sonuçlar KYB özellikleri açısından yeterli olsa da UK’ün yanında bir başka mineral katkının daha kullanılması ayrışma direnci daha iyi karışımların elde edilmesini sağlamıştır. Mineral katkılar bir miktar basınç dayanımını artırmakla birlikte donma çözülme çevrimler sonrasında daha fazla dayanım kaybına uğramıştır.
