5.2 Improvement of methods or data for environmental impact assessment (e. g. LCA - life-cycle analysis)
Cement production causes high amounts of energy consumption and accounts for about 5-8% of global CO2 emissions. Reducing cement consumption is very important in terms of contributing ecologically and economically to the future. In addition, the reduction in cement consumption contributes positively to climate change, which is among the world's priorities. In order to minimize cement requirement, the searching of alternative binding materials instead of cement are done by Scientists. The aim of this study is producing geopolymer concrete using different waste materials in order to reduce the cement utilization. The other aim of the study is improving the geopolymer concrete mixture properties by using of bacteria. In this regard, bacteria must be encapsulated in order to be included in geopolymer mortar mixtures. The fresh, rheological and hardened state properties of all cementitious systems are obtained in our accredited laboratory. However, for this study to be carried out successfully, we need partners experienced in encapsulation of bacteria.
Our construction materials laboratory was established in 2016 within the scope of the project supported by the Uludağ University Scientific Research Project Department. All fresh and hardened state tests of construction materials such as flowability, setting time, strength properties, modulus of elasticity, transport properties, ASR, the resistance of freeze-thaw, abrasion, high temperature, sulfate attack, acid attack and impact etc. are measured in our acridited laboratory. Besides, the Anton Paar MCR52 rheometer having ball measuring system is existed in our cement paste lab. The dynamic and static yield stress and apparance viscosity can be measured.
