The effects of Nano Silicate Mixtures with High Volume Fly Ash on High Performance Strengthening Mortar
Öz
In this study, 8 different mixtures were made. In these mixtures, silica nanoparticles were substituted for cement by 0% to 2% by 0.25%. The compressive and flexural strength of Nano Silicate Mixtures under the influence of high volume fly ash with low water content were investigated. 5×5×5 cm concrete cubic prisms were produced and subjected to compressive strength test on the 1st, 3rd and 7th days. These prepared concrete specimens were subjected to experiments on 1, 3 and 7 days. The aim of this study is to prevent the negative effect of high volume fly ash on the early age strength of concrete from the first day and to obtain high performance concrete.

Bu çalışmada 8 farklı karışım yapılmıştır. Bu karışımlarda, Nano Silikat %0 ’dan %2’ ye kadar % 0.25 arttırılarak çimento yerine ikame edilmiştir. Hazırlanan numunelerde su oranı düşük tutulup yüksek hacimde kullanılan Uçucu Külün etkisi altında ikame edilen Nano Silikatlı karışımların basınç ve eğilme altındaki davranışları araştırılmıştır. Numunelerde basınç dayanımı testi için 5×5×5 cm küp prizma betonlar hazırlanmış ve 1., 3. ve 7. günlerde deneylere tabi tutulmuştur. Bu çalışmanın amacı Nano Silikatlı numunelerin 1. günden itibaren Uçucu Külün erken yaş dayanımdaki negatif etkisini önlemek ve yüksek performanslı beton elde etmektir.
