SÜPER AKISKANLASTIRICI KATKILI BETONLARIN YÜKSEK SICAKLIKTAKI BASINÇ DAYANIMI

Ömer Can 1 , Gokhan DURMUS 2 , H. Süleyman GÖKÇE 3

Bu çalismada, süper akiskanlastirici katkili (SAK) betonlarin yüksek sicakliktaki mekanik özellikleri arastirilmistir. Bu amaçla kirma tas agrega, CEM I PÇ42.5 R çimentosu, SAK ve musluk suyu kullanilarak C20 sinifi beton üretilmistir. Taze betonlar üzerinde çökme, birim hacim agirlik ve ve-be deneyleri yapilmistir. Taze betonlar, 10*10*50 cm boyutunda prizma numunelere dökülmüs ve elde edilen numunelere 7 ve 28 gün standart kür uygulanmistir. 7 ve 28 gün yaslarda prizma numunelerden Ø5*10 cm boyutlu silindir numuneler alinarak 3 saat süresince 20, 100,200, 300, 400, 500 ve 700°C sicaklik etkisine maruz birakilmistir. Laboratuar kosullarina kadar sogutulan numunelerin basinç dayanimi belirlenmistir. Çalismada, yüksek sicaklik uygulanmis betonlara katilmis süper akiskanlastirici katkisinin mekanik dayanima etkisinin olmadigi görülmüstür.

THE COMPRESS STRENGTH OF CONCRETE MIXED WITH THE SUPER PLASTICIZERS IN HIGHER HEAT

Ömer Can 1 , Gokhan DURMUS 1 , H. Süleyman GÖKÇE 1

In this study, the mechanic properties of the concrete mixed with admixture of the super plasticizers (ASP) was tried to predict by the method of the multi-regression analysis and fuzzy logic. For this propose, the concrete of Classed 20(C20) was produced using the crushed Stone aggregate and cement of CEM I PÇ42.5 R and ASP and fountain water. The slump and unit volume and unit weight tests etc. were performed on these fresh concretes. The fresh concretes were casted with a dimension of 10*10*50 cm prism formed and the samples obtained from concretes were exposed to the heat effects curing for 28 days taking the cylindrical samples with a dimension of 5 and 10 cm in 3 hours long in turns 20, 100, 200, 300, 400, 500, and 700 degrees. The values of stress strength was tried to forecast using higher heat and ultra sound of transition speed value of samples cooled until the laboratory conditions. In the result of study, it was observed that there has been no effect on the properties of me
