ADDITIVES INFLUENCE ON THE PROCESSING CHARACTERISTICS OF REFRACTORY MIXTURES
Journal Title: Metallurgical and Mining Industry - Year 2018, Vol 10, Issue 2
Abstract
In this publication, the authors report on improving processability of concrete mixtures and the quality of monolithic linings for thermal metallurgical units and constructions. The certain result have been achieved with the introduction of expanded pearlitic sand as the additive of the mixtures thereof: the compositions of refractory mixtures with the additives of pearlitic sand (0.1%-1.8%) have been developed in order to permit both required placeability and structural strength of the mixtures. The work produced has allowed revealing the lamellar sliding effect which occurs with the grains of the filling between the pearlite layers. This effect provides the opportunities of both better placeability and structural strength of the mixture. In its turn, the better quality of monolithic linings is achieved.
