انتاج خرسانة حرارية عازلة من مواد محلية

Abstract

The research examines the possibility of producing insulating castable Refractory from locally available raw materials consisting of thermal aggregates represented by alumina bricks, which produce in large quantities in factories as industrial residues, and lightweight raw porcelainite aggregates as a partial replacement for thermal aggregates to give a lightweight character to thermal concrete, the white cement was also used at 25% and the white kaolinite at 5% to bind the ingredients, the castable which obtained is insulation refractory castable conforming to the requirements of the American specification ASTM C401 by porcelainizing aggregate in percentages (10, 15%) as a partial replacement of the thermal Alumina bricks aggregate, the dry density of manufactured refractory castable is (1.21, 1.24) g/cm3 with linear shrinkage at 1150c ° (1.38, 1.22)%, respectively.
