Abstract Scope |
Alkali activated materials (AAMs) have been studied as an alternative to replace the high demand for ordinary Portland cement (OPC) in the construction industry, with the use of industrial by-products in order to reduce and recycle waste instead of disposal in landfills. The aim of the research will be to analyze the properties in the hardened state of an alkali activated paste of metakaolin (MK) and residue from the flue gas desulfurization (FGD). Samples of AAMs, with dosages of 100% MK, 90% MK and 10% FGD, 80% MK and 20% FGD, will be produced with a thermal cure of 6 days at 60 ºC in the oven. Subsequently, the specimens will be subjected to tests of compressive strength, bulk density in the hardened state, water absorption and void index at 7 and 28 days. |
