ATIK ANDEZİT VE MERMER TOZUNUN ÇİMENTO HARÇLARININ DAYANIM ÖZELLİKLERİNE ETKİSİ

Abstract

The sludge generated during cutting of andesite and marble stones is stored in powder form after drying. Due to the wide usage area and consumption of marble and andesite, the storage problem of these wastes arises. Therefore, it is important to eliminate the storage problems of these wastes and to recover them to the economy. For this purpose, in this study, mortar samples were produced using 5%, 10%, 15% and 20% of waste andesite and marble powder separately instead of cement. Ultrasound pulse velocity, flexural and compressive strength tests were carried out on the produced samples. The experimental results showed that the most suitable substitution rate of marble powder used in this study is 10% and andesite powder 15%. In addition, the highest flexural and compressive strength values were achieved in mortars with 15% andesite powder substitution instead of cement.
