X-ray diffraction is a crucial method for characterizing crystalline materials, widely employed in the analysis of both products and raw materials in the cement industry, including clinker, cement, and limestone. Quantitative phase analysis via X-ray diffraction necessitates sophisticated computational tools to accurately interpret diffraction patt...

Lightweight concrete is increasingly utilized in sustainable construction due to its reduced weight and improved thermal performance. However, replacing conventional aggregates with alternative lightweight materials may result in a reduction in concrete strength. To address this issue, fiber reinforcement has been introduced to enhance the concrete...

  This study presents the results of applied phytoextraction as a soil phytoremediation method, based on the analysis of selected heavy metal content in soil and plant material. The selected locations where phytoextraction was applied as a phytoremediation method (Gradišće, Podbrežje, and Tetovo) are situated in the city of Zenica, in ...

This project investigated the potential of using dolomite from Central Bosnia as a raw material for high-purity metallic magnesium production. Extensive sampling and mineralogical analyses revealed the suitability of these deposits, particularly for methods like the Pidgeon Process. Preliminary results underscored the strategic value of Bosnia&rsqu...

Two clays from deposits located in the region of Central Bosnia, and kaolin obtained from a localspark plug and technical ceramics factory were calcined at 800, 900, and 1000 ºC. The pozzolanicactivity of calcined raw materials was determined using the P test. Calcined clay from the depositBilalovac showed slightly better reactivity compared t...

This paper examines the possibility of producing metallurgical cement type CEM III/A 42.5N at theKakanj Cement Factory. The tested samples contain respectively 46%, 41%, and 38% of granulatedblast furnace slag and the rest is clinker. According to the test results, all cement samples meet theEN 197-1 standard in terms of physical-mechanical propert...

The strength development of concrete containing ground granulated blast-furnace slag (GGBS), aby-product of iron in blast-furnace, as a partial substitute for cement,was experimentally studied.Levels of replacement of cement by slag were 12.5 %, 25 %, 37.5 %, and 50 % by weight ofcement. Slag taken immediately after it was discharged from the blast...

The paper examined the changes in properties of conventional castables composed of a mixture of calcium-aluminate cement and chamotte caused by changes in the particle size distribution. Properties of castable with 20 % cement and „as received“ chamotte were compared with castableofparticle size distribution adapted to the calculated di...

Particle size distribution measurements were performed on ground granulated blastfurnace slag by laser diffraction with the powder dispersed in distilled water with sodium hexametaphosphate used as dispersing agent, as well as in pure distilled water and propan-2-ol. Two samples of slag with Blaine fineness 4700 cm2 /g and5500 cm2 /g were tested.Th...

This paper presents an experimental investigation into the effect of nanosilica addition to porosity and capillary absorption of concrete. Three concrete mixtures 0%, 2%, and 4% nanosilicaby weight of cementweretested.The procedure described in ASTM C642-06 was used to determine the total volume of permeable voids.Water absorption and the rate of w...
