A study on fracture toughness of ultra-high toughness geopolymer composites based on double-K criterion

Ultra-high toughness geopolymer composites (UHTGC) were fabricated based on the matrix of binder composed of alkali-activated fly-ash and granulated blast furnace slag and polyvinyl alcohol (PVA) fibres in this research. The tensile behaviour and fracture toughness of UHTGC are investigated on both macro and microscales experimentally and...

Understanding real estate markets with big data: liquidity and rental co-movements in Germany

Market liquidity conditions and rental growth are said to match along “hot” and “cold” market cycles over time. Substantial deviations from these phases explain either overrented or underrented expectations by landlords or an essential change in tenants’ housing demand. While the assessment of housing markets by central banks, governments,...

The political struggle on and at Kizilay square with respect to perceived, conceived and lived public space before and after 1980

Workshop 3. Politics of public space Abstract: Since the time it was conceived as a socio-spatial project of new established Republic of Turkey, K?z?lay Square in Ankara has been reproduced within its (historical) meaning, (urban) function and (spatial) form, through changing contradictions and actors within political, social and economic...

Towards Detached Eddy Simulation Modelling Using a k-Equation Turbulence Model

A detached eddy simulation modelling approach is presented for turbulent flow computations, which is based on the transport equation for turbulent kinetic energy, k (and thus termed k-DES model). The model coefficients in the RANS form are calibrated in wall-attached flow computations, and the LES mode is calibrated in the simulation for...
