M. Górny, R. Dańko, M. Holtzer. AGH University of Science and Technology, Faculty of Foundry Engineering, Kraków, Poland This article addresses the effect of mold filling and wall thickness on the flake graphite layer in ductile iron. The research was conducted for castings with different wall thickness (3-8 mm) and using molding sand with furan resin. A thermal analysis has been performed alon...

This work presents a study on the effects of luffa fibers and gamma radiation as tools for mechanical improvement of polymer concrete based on a polyester resin/foundry sand mixture. Different concentrations of irradiated and non-irradiated fibers (0.3, 0.6 and 0.9 wt%) and higher irradiation doses were used. The results show that the compressive strength and flexural strength values decrease g...

Ł. Jamrozowicz, J. Zych, J. Kolczyk, AGH University of Science and Technology, Faculty of Foundry Engineering, Kraków, Poland Investigation results of the drying rate of the selected protective coatings (water and alcohol) are presented in the article. Coating drying rate was determined for the first and second layers. The coating was applied to moulding sand cores. The rate of drying coatings ...

In the present study, an attempt is made to find usage and utilization of by-products or recycledmaterials in bituminous paving mixes. The experiment started with conduction basic tests for various materials like Coarse aggregate, Fine Bitumen, by-product recycled copper slag, foundry sand, brickbats. These were tested their suitability carrying out work as a prediction know alternative these m...
