Abstract Scope |
Today's society has a growing demand for Portland cement, however, the production of clinker uses a high amount of energy and releases a large volume of greenhouse gases. The search for more sustainable production processes has permeated several sectors of academy and industries, in this context, geopolymers have been widely studied as an alternative proposal to conventional cement. Steel fibers are an important reinforcement for high mechanical performance concretes and mortars. In this work, composites were prepared with a geopolymeric mortar matrix, reinforced with 1.5% and 3.0% of steel fiber, in relation to the mass of metakaolin used as precursor element. Studies were carried out on the gain of mechanical properties, with compression and flexural strength. In addition to the mechanical properties, water absorption and density tests in the hardened state were performed. The tests showed good properties of the composites produced. |
