YAPAY HAFİF AGREGA İLE MODİFİYE EDİLMİŞ, Na2SO4 VE NaCl ETKİSİNDEKİ KENDİLİĞİNDEN YERLEŞEN HARÇLARDA BASINÇ VE EĞİLME DAYANIMINA NANO SİLİKA KULLANIMININ ETKİSİ

Melek AKGÜL1

Harç ve türevlerinin üretiminde agregaya ikame ürün arayışında yapay hafif agrega önemli bir alternatiftir. Ayrıca çimento miktarını azaltmak için ikame ürün arayışında nano silika kullanımı son yılların önemli bir araştırma konusudur. Bu çalışmada agrega %0, 5, 10 ve 15 oranında yapay hafif agrega ve çimentoya %1, 2, 3, 4 oranında nano silika ikame edilmiştir. Üretilen numuneler 3 gruba ayrılmış ve 28 gün süresince 1. grup standart su küründe 2. grup 100 ml/L Na2SO4 derişimli çözeltide, 3. grup ise %4 NaCl derişimli çözeltide bekletilmiştir. 28 günün sonunda tüm grupların eğilme ve basınç dayanımı verileri kıyaslanmıştır. Artan nano silika miktarı %3 mertebesine kadar porozite, basınç dayanımı ve eğilme dayanımı üzerinde pozitif etkiye sahiptir. Artan yapay hafif agrega miktarı ise %10 mertebesine kadar kabul edilebilir eğilme ve basınç dayanımı değerleri sunmaktadır. Bu hali ile çalışma yapay hafif agrega kullanımına bağlı basınç ve eğilme dayanımı kayıplarında iyileştirici nano silika oranlarının tespiti anlamında veriler sunmaktadır.

THE EFFECT OF NANO SILICA USE ON COMPRESSIVE AND FLEXURAL STRENGTH IN SELF-COMPACTING MORTARS MODIFIED WITH ARTIFICIAL LIGHT AGGREGATE UNDER THE INFLUENCE OF Na2SO4 AND NaCl

Melek AKGÜL1

Artificial lightweight aggregate is an important alternative in the search for substitute products for aggregate in the production of mortar and its derivatives. Furthermore, the use of nano silica in the search for substitute products to reduce the amount of cement has been an important research topic in recent years. In this study, 0, 5, 10 and 15% of the aggregate was replaced with artificial lightweight aggregate, and 1, 2, 3, and 4% of the cement was replaced with nano silica. The produced samples were divided into 3 groups and kept for 28 days: group 1 in standard water curing, group 2 in a solution with a concentration of 100 ml/L Na2SO4, and group 3 in a solution with a concentration of 4% NaCl. At the end of 28 days, the flexural and compressive strength data of all groups were compared. Increasing nano silica content up to 3% has a positive effect on porosity, compressive strength, and flexural strength. Increasing the amount of artificial lightweight aggregate up to 10% provides acceptable flexural and compressive strength values. In this context, the study provides data for determining the optimal nano silica ratio to mitigate compressive and flexural strength losses associated with the use of artificial lightweight aggregate.
