Investigation of Compressive Strength of Plaster and Masonry Mortar Prepared with Waste Stone Dust, Nano Carbon Black and Cement
Keywords:Stone dust, Recycling, Mortar, Nano Carbon Black
Mortar and concrete produced by replacing the cement or aggregate in the traditional concrete mixture or a certain proportion thereof with natural or artificial mineral admixtures are becoming increasingly common. With these admixtures, the properties of fresh and hardened mortar are aimed to be improved. Wall and plaster mortars are expected to be as durable and waterproof as bricks. Especially, the freezing-thawing resistance of exterior plaster materials and flooring materials should be high. In addition, soil surfaces are susceptible to wind and water erosion effects. It is known that such surfaces are covered with abrasion resistant plaster material in order to protect it against abrasion on soil surfaces. In this study, the usability of the mixture obtained by incorporating waste materials, such as stone dust and nano carbon black, with a certain amount of binder, such as cement, as ready plaster, masonry mortar or ground coating material are investigated. When soil surfaces under the effect of wind and water erosion are covered with the mortar obtained with this fine powdered ready-made material, a stance against erosion will be displayed. If the material meets the current standards in terms of both tension and durability, it can be put on the market as a ready-made plaster mixture in 20-40 kg bags in fine powder form. Currently, nano carbon black is available on the market in 20 kg paper bags. Stone dust is found in mining companies that process mud or rock in dry form.
