Alternatives materials in the construction industry

Abstract

The environmental problems associated with the production of Portland cement has concern the manufacturer industry due to the amount of CO2 emitted into the atmosphere. Subsequently, some alternatives have emerged in order to get a cleaner production without altering its quality using technology innovation in cement plants. This research is based on the analysis and design of alternatives cementing materials using waste and industrial by-products. The first one is a subproduct made from the steel industry and the second one is a waste product form the glass industry. When both materials are mixed, they create what it is called Alkali-Activated Inorganic Binders (AAIB) from the, The Basic Oxygen Furnace Slag (BOF Slag), and the Thin Film Transistor Liquid Crystal Display (TFT-LCD), glass powder This purpose of this research was to obtain a binder similar to the Portland concrete with a minimum compression strength of fc’=18.51 MPa in 14 days. It is considered an available option I the construction industry due to it similar characteristics to the OPC; Furthermore, it has been accomplished a significant CO2 reduction as a result of partial or total replacement of cement.
