“…The reduction of the density, by using 1.0% of SP, confirms the findings of Alaka et al 2016, [43] and Łaźniewska et al 2012, [44]. However, increasing the density by using 2.0% of SP occurred due to the high increase in the dispersity of the fine grains which increases the packing density [45].…”

Since the foam concrete is delicate, it is important to carefully choose the additives, such as superplasticiser (SP), to be used in this type of concrete. The effect of using different types and percentages of SP on the performance of foam concrete with target density of 1500±50 kg/m3 has been investigated in this study. A sustainable material, Palm Oil fuel ash (POFA), used as a sand replacement at a level of 20% by weight. Five types of SP have been used in this study, including Sulphonated polymer-based, selected synthetic and organic polymers-based and three Polycarboxylate ether-based (PCE). Different SP contents (0.0%, 1.0% and 2.0%) have been used as a ratio of cement weight. Workability, consistency, foam stability and mechanical properties were investigated. The results showed that types and quantity of SP have a significant effect on the different properties of the foam concrete. Workability, compression strength and tension strength improved remarkably for most specimens. The use of 2% SP4, a PCE SP, showed superior workability, compression strength and tensile strength with acceptable stability.

“…The important characteristics of segregation are (i) the bleeding of water, (ii) paste and aggregate segregation, (iii) coarse aggregate segregation leading to blockages, and (iv) non-uniformity in air-pore distribution (Tangtermsirikul and Khayat, 2000). The problem of the segregation of the water and aggregates can be solved by simply reducing either the water content or the surface powder (Kismi et al, 2012). Fig.…”

“…Bu sonuçları kontrol altına almak amacıyla kullanılan süperakışkanlaştırıcı katkıların tipi ve oranın tayinin doğru bir şekilde yapılması gerekmektedir. Süperakışkanlaştırıcıların etkinliği ve bağlayıcılığı; çimento bileşimi, beton bileşenleri ve karıştırma koşullarındaki ufak değişimlerden büyük ölçüde etkilenmektedir [18].…”

Hafif agregalarla yapılan hafif betonlar genel olarak; geleneksel betona göre daha düşük birim hacim ağırlığa, daha iyi ısı yalıtım ve yangın direnci özelliklerine sahiptirler. Önemli hafif agregalar arasında yer alan genleştirilmiş kil agregası (GKA) en iyi basınç değeri veren hafif agregalar arasında yer almaktadır. Bu çalışmada agrega olarak 0-500 µm, 0-3 mm, 3-8 mm, 8-16 mm ebatlarında GKA ve 4 farklı süperakışkanlaştırıcı katkı malzemesi (SA) kullanılarak, su/çimento (S/C) oranı 0.40, 0.45, 0.50 oranlarında hazırlanan numuneler üzerinde fiziksel ve mekanik deneyler yapılmıştır. Yapılan yayılma, basınç dayanımı, birim ağırlık, su emme ve kılcal su emme deneylerinin sonuçları değerlendirildiğinde, çalışmada kullanılan süperakışkanlaştırıcı katkıların bu hafif agregalı beton için uygun tipte olduğu anlaşılmıştır.
