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...

Public demand for environmentally friendly solutions for new types of cement with reduced CO₂ emissions is increasing. Consequently, new types of cement must be developed and introduced to the market. This paper presents test results for cement formulations based on calcium fly ash and marly limestone, following the EN 197-5 standard. The clinker c...

Fillers play a crucial role in enhancing product performance and reducing production costs. To be used in various industries, fillers must be readily available, affordable, pure, non-toxic, and meet specific physical and chemical standards. This study examines limestone and dolomite fillers, focusing on their chemical composition, mineralogical pro...

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...

Fuels are substances that release heat energy during combustion due to the oxidation process that occurs. In order for a substance to serve as fuel, it is important that it has a high calorific value, which is most affected by the carbon content. Sulfur has a very small effect on this characteristic of the fuel but is considered as a negative compo...

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...

According to new EN 197-5 is possible to combine clinker with blast furnace slag, silica fume,pozzolana, fly ash, burnt shale, and limestone from 36 – 50% while clinker content should be from50 – 64%. In this paper are presented results of laboratory testing concerning CEM II/C-M(S+W) production where a sample is prepared by mixing 50% ...

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...

This paper presents an experimental study to evaluate the possibility of CEM IV 42,5N producing by increasing the specific cement surface from 3180 to 3850 cm2 /g. In this paper, fly ash is used as a cement admixture because fly ash possesses both hydraulic and pozzolanic properties. If one part of the clinker, as a major cement admixture, is repla...

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...
