  • RECEMENT-RE-GENERATING (RAW) MATERIALS AND END-OF-LIFE PRODUCTS FOR RE-USE IN CEMENT/CONCRETE

Researcher (PI: Mehmet Ali Gülgün, Sabancı University)

*The proposed project aims to provide low-energy, low CO2 and low-cost alternative binding materials by re-generating end-of-life (EOL) materials mined urban construction and mineral deposit quarries for replacing ordinary Portland cement (OPC).

  • NATURAL MINERALS AS A PROTECTION BARRIER FOR MICROORGANISMS IN SELF-HEALING MORTARS

Primary Investigator (PI)

The project aims to develop an automated system enabling additive manufacturing of cement-based composites. This is an extensive study undertaken to design a two-phase system to induce self-healing via biomineralization in cement-based materials.Within the scope of proposed project, the impact of self-healing on corrosion resistance and plastic shrinkage cracks will also be evaluated.

Completed Projects

  • BIO-BASED ADMIXTURES TO MODIFY RHEOLOGY OF CEMENT-BASED MATERIALS
Primary Investigator (PI) Funded by TUBITAK-THE SCIENTIFIC AND TECHNOLOGICAL RESEARCH COUNCIL OF TURKEY, TURKEY- 1005 NATIONAL NEW IDEAS AND PRODUCTS R&D FUNDING PROGRAM (15.03.2017-15.09.2018) Project Title: Bio-based admixtures to modify rheology of cement-based materials (116M183) Özyeğin University Istanbul, Turkey, Budget: €65000 /Duration: 18 Months

*The project goal was to design a bio-based superplasticizers and viscosity modifying agents for cement-based materials to optimize the cost of admixture by using waste or environmental additives. A final product (BIOCRETE) was established upon completion.

  • USE OF BIOMINERALIZATION IN RECYCLED AGGREGATE CONCRETE

Researcher (PI- Nilüfer Ozyurt, Bogazici University)

* This collaborative research aims to improve the mechanical properties of recycled aggregate concrete by using MICCP. Calcium carbonates are induced via urealytic Sporosarcina pasteurii and deposited within the cracks and inclusions on recycled aggregates.

  • BACTERIAL SELF-HEALING CONCRETE

Researcher (PI: Nele De Belie, Ghent University)

*Worked on bacterial self-healing concrete within the scope of EU FP7-SHeMat project

*Evaluated influence of air entraining admixtures on viability of vegetative cells incorporated in mortar

*Investigate the influence of vegetative cells, nutrients, and AEA on hydration kinetics on different cement types.

  • BIOMINERALIZATION FOR SELF-HEALING CEMENT-BASED MATERIALS
Primary Investigator (PI)- Funded by TUBITAK-THE SCIENTIFIC AND TECHNOLOGICAL RESEARCH COUNCIL OF TURKEY, TURKEY- CAREER DEVELOPMENT GRANT (CAREER) Project Title: Biomineralization for self-healing cement-based materials Özyeğin University Istanbul (114M328), Turkey, Budget: €47500 /Duration: 30 Months

*The project goal was development innovative self-healing cement-based material via use of biomineralization

*Microorganisms were cultured in a corn-steep liquor/urea medium and directly incorporated in mortar without any protection.Self-healing of flexural cracks was obtained at 7-day old mortar samples.Water absorption was decreased through crack healing

*Durability of bio-based sealant was related to morphology of calcium carbonate within the cracks

*Use of chemical admixtures did not affect the self-healing ability.

  • BIOMINERALIZATION IN CEMENT-BASED MATERIALS: INOCULATION OF VEGETATIVE CELLS

Graduate Research Assistan, UT Austin

*Developed a self-healing mortar for micro-cracks at early ages.

*Developed a bio-smart material in order to increase the service life of cement-based structures.

*Evaluated microstructure, hydration kinetics, compressive strength, porosity, and electrical resistivity of cement-based materials.
