Impact of waste materials on hygric transport parameters of low-cement heat-resistant composites

Popis výsledku v původním jazyce

This article is focused on the low-cement-based refractories produced with the application of waste materials. Ceramic powder and waste metashale were employed, both latter materials are by-products rising in industrial productions, and their application would propose important ecological benefits. These secondary raw materials were used for partial binder replacement, specifically 60% of calcium aluminate cement was replaced by them. The main aim of this study was to assess the impact of chosen waste materials on the water and water vapour transport properties of the refractories at ambient temperatures as well after exposure to 400 °C, 1000 °C and 1400 °C. Except for hygric properties, basic physical characteristics such as bulk density, matrix density and porosity and pore size distribution curves were determined as well. From the hygric properties, water vapour diffusion resistance factor, water absorption coefficient and apparent moisture diffusivity were investigated. Application of both ceramic powder and waste metashale led to a noticeable increase in water transport ability, regardless of its physical state.
