Brief description of the project: Cement is one of the most popular and widely applicable building materials. During of cement production, the burning of limestone causes the emission of carbon dioxide into the atmosphere, which amounts to 5% of the total CO2 emission. During the production of 1 ton of cement, approximately 1 ton of CO2 is emitted into the atmosphere. If we consider that the world production of cement is about 4.18 billion tons, then it can be seen that during the production of cement, the same amount of CO2 is released into the atmosphere. The concept of “green cement” was developed as a replacement for current cement production methods. Green cement uses less natural raw materials, energy and water and is emerging as a substitute for Portland cement. Green cement means cement that is produced with as little consumption of natural raw materials and fossil fuels as possible, and with maximum use of man-made waste materials as raw materials for the production of cement and alternative fuels instead of fossil fuels.
These reasons have led to the research of new binding materials, which are similar to cement, but have much better physical and mechanical properties, are more ecologically and economically acceptable, and are called geopolymers.
Geopolymers are actually inorganic, solid, stable and non-flammable at high temperatures, polymer materials that have the property to transform, polymerize and harden at low temperatures in the presence of alkaline activators. The application and development of geopolymers as an alternative to traditional cements is becoming more and more likely due to a series of problems related to the cement industry.
The main goal of the research is to determine whether it is possible with the help of alkaline activators added to mineral additives (ash, slag, etc.) to obtain an inorganic, solid, stable and non-flammable geopolymer material that has the same or better properties than Portland cement or concrete.

Brief description of the project: A scientific research project whose main goal is to determine whether it is possible to obtain a mineral admixture for concrete based on low-kaolin clay that will have satisfactory performance characteristics. Experimental research is aimed at determining the influence of the addition of calcined clay on cement binding and hardening processes and on the properties of fresh and hardened concrete. The total value of the project is 38,123.50 KM, of which the Federal Ministry of Education and Science participates with 15,673.50 KM. In addition to the University Zenica, the Faculty of Mining, Geology and Petroleum of the University of Zagreb and the company CELAB d.o.o. Kakanj participate in the implementation of the project.

Brief description of the project: Titanium alloys are considered advanced materials due to their special properties. Deficiency applications of titanium alloys are extremely high prices of raw materials, as well as difficulties in machining this material into the final geometry, i.e. low material utilization. Thanks to the techniques that “eliminate” machining such as powder metallurgy, the loss of this relatively expensive is reduced materials, and it is possible to obtain products with complicated shapes.
The subject of the research is titanium alloy – Titan Grade Nb / EN TiAl6Nb7 / ASTM F 1295 which is developed for medical use when the cytotoxic vanadium was replaced by niobium. This alloy has high strength, corrosion resistance, excellent bio-compatibility and does not cause chemical threads immune reactions in the human body.
A powder was produced from the samples of this alloy by means of the simulation of the HDH (hydride-dehydride) procedure, with using a modified furnace for heat treatment with a protective atmosphere located in JU “Center for Advanced Materials in Sarajevo”.
The essence of the HDH process is to convert titanium alloys into inter-metallic metal compounds and hydrogen so called hydrides by absorbing a considerable amount of hydrogen. Formed compounds cause brittleness alloys, which can then be mechanically crushed to the desired particle size. Hydrated powder then it is heated again in a vacuum or a protective atmosphere, during which hydrogen is released. U this process produces titanium alloy powder of unchanged chemical composition, with an irregular shape particles and more favorable mechanical and physical properties. The resulting powder was analyzed on an SEM microscope Faculty of Science and Technology (SCT) – Department of Metallurgy and Materials, University of Ljubljana. The hydration process carried out was successful because the hydrated sample could be relatively easily mechanical by chopping to the desired size. In this experiment, the necessary parameters for hydration process and according to the size of the recycled product, related to thermal treatment. By procedure grinding of the hydrated sample achieved favorable particle sizes, mostly below 60 microns. The results obtained in this research point to the possibility of developing the HDH procedure as economic procedure for the production of “low-cost” high-value powder based on titanium alloy.
