Description

Scientifically there are no more doubts about the impact of humans on global warming. The raise of earth temperature causes environmentally related problems. Evidences show the most influencing GHG is CO2. Many human activities release this GHG as a byproduct. Generally, the two industries contributing to this are the energy production and construction. The GWhrs of Kosovo energy, (in 2013, 5864 GWh) emit kilotons of CO2. The emission of CO2 in 2013 was 7896.0 kton, i.e. 1.3t/MWh. On the other side, the concrete industry, the second most used material, which uses cement contributes with other tons of GHG, almost each ton of cement contributes with one tone of CO2 emission. The other negative impact of energy sector is production of combustion byproducts. The interest of this study is the residue in the form of ash- Fly ash, which in terms of production is around 1 Mt annually. In 2013 Fly ash generation was 1.5 Mt. This is the physical threat to environment. The aim of this study is the mitigation of CO2 emissions in Kosovo. It is used worldwide, and we cannot be an exception. The chemically tested Fly ash is added to concrete as cement substitute and the test results showed to positively approve its use. So, each one kg of cement substitution with fly ash is the one kilogram less CO2 in the atmosphere. Our physical and mechanical tests results showed that our concrete “absorbs” tons of CO2, being so friendly to environment, being friendly to people. This is a good track of Kosovo to comply with EU targets on reduction of GHG. The historians, as the named ages: “the stone age”, “the bronze age”, “the iron age”, they must name our millennium: “the concrete age”.
