The effect of different puzzolanic additives on mechanical properties of cement mortars
Bu çalışmada, Soma termik santralinden elde edilen uçucu kül, iki farklı tras (Yenişehir, Bilecik) ve silis dumanı, çimento klinkerinin bir kısmı yerine katılmış ve elde edilen harçların basınç dayanım değerleri incelenmiştir. Ağırlıkça %5 silis dumanı içeren çimentoya %10 uçucu kül katılmıştır ve tras oranları ise %30, %35 ve %40 olarak değiştirilmiştir. Bu karışımların her birinin kimyasal analizleri yapılarak Blaine özgül yüzey alanı değerleri ölçülmüştür. Bu bulgular ışığında basınç dayanım sonuçları irdelenmiştir. Yapılan denemelerde en yüksek dayanım değerlerinin Bilecik trası ile hazırlanan ve yüksek inceliğe sahip olan puzolan içeren harçlarda elde edildiği saptanmıştır.In this study, cement mortar samples containing fly ash obtained from Soma Power Plant, two different types of natural pozzolan supplied from Yenişehir and Bilecik and silica fume from Antalya Ferrocrom Industry partial replacement of cement clinker. The strength of the mortars prepared by these mixtures were investigated. The mixtures were prepared by using 10% fly ash and 5% silica fume and the trass contents varied as 30%, 35%, and 40%. Chemical analyses of these mixtures were carried out and Blaine specific surface area values were measured. In performed tests, the highest strength values were noticed in mortars containing natural puzzolan from Bilecik which has high fineness
Evaluating Waste Marble Dust as Floor Tile
This work aims to evaluate waste marble dust in building industry therefore minimizing the environmental effects of waste dust and maximizing economic benefits with reducing the use of raw material and energy. The marble process industry generates a large amount of wastes during quarrying and sawing processes which pollute and damage the environment. There are many fields in which the marble wastes can be used, one of them is to use them in building industry. In this work, marble dusts provided from 3 different quarries, coming from 3 different places were coded as BN1, BN2 and BN3. After characterizing tests of the dust, they were used in the production of artificial marble tiles using a different amount of resin binder. By the respective physical, optical, chemical, and mechanical tests the maximum quantities that can be added have been determined. The results show that using 80 wt.-% marble dust and 20 wt.-% resin gives the best properties in tiles

Use of waste marble powder in brick industry
The usability of waste marble dust as an additive material in industrial brick were investigated. Marble wastes were collected from marble deposits which are located at Southwest of Turkey and industrial brick mortar was obtained from a brick company in Istanbul. Waste marble dust and brick mortar were prepared for various processes of industrial brick investigation. Waste material in different proportions was mixed with industrial brick mortar starting amount of 0 wt.% up to 80 wt.%. in 41 x 8 x 8 mm rectangular prisms for testing of physico-mechanical properties of the samples having different marble dust composition. These prepared prisms were pressed and sintered at three different temperatures 900, 1000 and 1100 degrees C. Flexural strengths of the test samples were given at three different temperature values of 900, 1000 and 1100 degrees C. Archimedes water displacement test was conducted with different water absorption percentage values at 900, 1000 and 1100 degrees C temperatures. XRD analyses have been carried out for the additives which contain mainly calcite and small amount of dolomite minerals. It was found that the amount of marble dust additive had positive effect on the physical, chemical and mechanical strength of the produced industrial brick. With increasing demands of the construction industry, bricks quality and cost become more important day by day in Turkey. In addition, the usage of marble wastes for the production of industrial bricks has significant important role on the recycling waste marble powder in the brick production along with a great contributions to economy and ecology of the country
