Coagulation of cement particles is an inevitable phenomenon of fresh cement-based materials undergoing solidification. Coagulation can be classified into two types, reversible flocculation and irreversible coagulation, wherein microstructural change affects the rheological properties, including shear thinning and thixotropy, and the hydration process. This paper attempts to measure the mechanic...

Purpose: The aim of the work is presents the influence of casting method and anodic treatment parameters on properties, thickness and structure of an anodic layer formed on aluminium casting alloys. Design/methodology/approach: Investigations were carried out on the laser profile measurement gauge MicroProf from company FRT, abrasive wear test was made with using ABR-8251 equipment delivered by...

Abstract — Ceramic shell investment casting process is used to produce high quality metal products with relatively close dimensional tolerances. The refractory primary slurry that is applied to the surface of the pattern assembly, to pick up its surface details plays a very important role in ceramic shell investment casting process (CSICP). It produces a smooth, acceptable surface finish of the...
