The experimental study about the usage of silica fume in mortar plaster production

Bu çalışmada, silis dumanının sıva harcıyla olan ilişkisi araştırılmıştır. Bu amaçla silis dumanı, %0, %5, %10 ve %15 oranlarında çimentonun ağırlıkça yerine kullanılmıştır. Silis dumanının sıva harcındaki; kıvam, boşluklu birim hacim kütlesi, eğilme dayanımı, basınç dayanımı, alt tabakaya yapışma dayanımı ve su emme, özellikleri üzerine olan etkisi deneysel olarak incelenmiştir. Deney sonuçlarında; kıvam, taze harcın boşluklu birim hacim kütlesi ve su emme değerleri silis dumanı oranı arttıkça azalmış ve eğilme, basınç ve yapışma dayanımında artış gözlenmiştir.

In this study; the relation between silica fume and mortar plaster was investigated. For that reason; silica fume was replaced with 0%, 5%, 10%, 15% of cement weight. The effect of silica fume on consistency, unit volume mass, bending strength, compressive strength, water absorbtion and adhesive strength of mortar plaster were investigated by experimental methods. In the experiment results; it was seen that consistency, unit volume mass and water absorbtion values of fresh concrete have decreased by increasing silica fume ratio and also it could be seen that; as the silica fume ratio have been increased, bending, compressive and adhesive strength have increased.
