A review: The strength influence factors of slag and fly ash based alkali activated materials

Alkali-activated materials(AAM) are known to be environmentally friendly alternatives to cement-based materials because they can potentially reduce greenhouse gas emissions and reutilize industrial by-products. However, the application of AAM is still limited by the lack of mixture design regulation. Unlike cement, the very different chemical...

Modelling of microstructure of ASR influenced cement-based materials

ASR (alkali-silica reaction) is one of the toughest durability problems in engineering. However, the damage induced by ASR is still fairly unpredictable due to the lack of microstructural information of cement-based materials affected by ASR, while the microstructure determines the global performance. In order to fill this gap, a multiscale...

3D printing of cementitious materials with superabsorbent polymers: a durable solution?

Nowadays, 3D printing of cementitious materials is a hot research topic in the construction industry. This construction method is capable of producing complex geometries and largescale components without the use of expensive formwork. However, due to the lack of molding, more shrinkage will be induced and the amount of cracks will increase. As...

Will ortho-enriched water increase the durability of concrete?

Water molecules exist as two spin isomers, differing by the relative orientation of the nuclear spins of the two hydrogen atoms: either antiparallel (para-water, S=0) or parallel (ortho-water, S=1) [1]. The transition between these nuclear spin states can be achieved through magnetic symmetry breaking via a field gradient across the spins...

Robust marker-tracking system for vision-based autonomous landing of VTOL UAVs

This article presents the development of a visionbased VTOL UAV docking system for outdoor applications. A new marker type is constructed, along with a robust detection algorithm based on the Hough transform, which forms the basis of the positioning system. For verification purposes, a binary classifier based on support vector machines is...
