Investigation of Usability Potential Geopolimer Concrete at Animal Barns Abstract

Abstract

Portland cement, which causes significant energy and raw material consumption, is responsible for about 7% of CO2 emissions. In order to reduce CO2 emissions from cement production, with the aim of using a binder with a lower CO2 release or investigation of different methods, alternative materials to cement are required. In contrast to portland cement (PO), which is used in concrete production; geopolimer is a material that is potentially useful as an alternative to cement and is still being explored provides a very low CO2 emission, a high resistance to salts and acids, and a high temperature and fire resistance. In this study, the effects of geopolymer concrete were investigated in animal barn. For this purpose, samples were prepared using calcite aggregate, alkali activator and activation solution. As alkali activator of geopolymer material ceramic sludge (ST) is used at 20% of blast furnace slag (YFC). Sodium silicate (Na2SiO4) and sodium hydroside (NaOH) were used as the activation solution in 60-40% mixing ratio. Bending and compressive strengths were determined in 4×4×16 cm specimens and shrinkage ratios were determined on 25×25×285 mm specimens. In order to determine the conditions of the animal shelters of the geopolymer concrete, the strengths of the samples in 10% sulfuric acid (H2SO4) and sulphate (SO4) solution were compared with 28th, 56th and 90th days. It has been seen that the use of geopolymer concrete in animal barn can provide advantages.
