Foundry sand cores based on organic binders have required tensile, compressive, and bending breaking points, as well an excellent knocking‑out ability. However, increased requirements for the environmental friendliness of foundry led to a renewed interest in inorganic including sand‑liquid‑glass core‑making technology. are significantly inferior terms ability due using sufficiently large mass f...

The increased risk of lung cancer among foundry workers is assumed to be associated with the inhalation of gaseous and particle bound polycyclic aromatic hydrocarbons (PAH). These compounds are produced during pyrolysis of carbon containing loading material in the moulding sand. The concentrations of 20 PAH, some of which are carcinogenic, have been determined in the dusty casting area of an ir...

Cement-treated bases are soils, gravels or manufactured aggregates mixed with certain quantities of cement and water in order to improve the characteristics a base sub-base layer. Due exploitation natural aggregates, it is matter importance avoid shortage resources, which why use recycled practical solution. In this paper we studied feasibility untreated electric arc furnace slags foundry sand ...
