The kinetic competition between transport and oxidation of ferrous ions governs precipitation of corrosion products in carbonated concrete

open access: yesRILEM Technical Letters, 2018
Corrosion products, originating from steel corrosion and precipitating in the concrete pore system, can lead to concrete cracking and to spalling of the concrete cover. Related premature structural repair causes high costs.

$M$Si$_{20}$H$_{20}$ Aggregates: From Simple Building Blocks to Highly Magnetic Functionalized Materials

open access: yes, 2013
Density-functional theory based global geometry optimization is used to scrutinize the possibility of using endohedrally-doped hydrogenated Si clusters as building blocks for constructing highly magnetic materials. In contrast to the known clathrate-type

Effects of temperature, pH and calcium-to-carbonate ratio on the calcium carbonate polymorphs

open access: yesDiscover Civil Engineering
The precipitation of calcium carbonate (CaCO3) polymorphs (calcite, vaterite, and aragonite) plays a crucial role in tailoring the physicochemical properties of construction materials during mineral carbonation.

Digital wood craft [PDF]

open access: yes, 2009
In 1995, Robin Evans points out in his book The Projective Cast how the development of techniques changed architecture and the space inhabited in times of Gothic and early Renaissance. We see a parallel phenomenon today, where the interplay of technology
