Production and mechanical properties of alkali–activated inorganic binders made from wastes solids

Abstract

The environmental problems associated with the production of Portland cement has concerned the manufacturing industry due to the amount of CO2 emitted into the atmosphere worldwide Due to some of the environmental problems associated with the production of Portland cement some alternatives has emerged to try to obtain the sustainable development through technological progress in the cement plants; using alternative materials (waste and industrial by-products) for the development of new cementing materials more eco-efficient The aim of this research is the production and mechanical properties of Alkali-Activated Inorganic Binders (AAIB) made from The Basic Oxygen Furnace Slag (BOF Slag) and Thin Film Transistor Liquid Crystal Display (TFT-LCD) glass powder (waste and industrial by-products) Many factors have an influence on the production of AAIB like the glass powder finesses the alkaline equivalent content (AE %) water binder ratios (w/b ratios) and the differences curing process The findings show different behavior in the AAIB related to the factors mentioned the best results are given with a glass powder fineness of 4 500 cm2/g w/b=0 30 a curing temperature of 70 ℃ curing duration of 4 days and an aging duration of 14 days results in the highest compressive strength of 18 51 MPa
