TL;DR: In this article, the pyrogenic aragonite was found to form at ambient temperatures and pressures upon carbonation of calcium oxide and calcium hydroxide together with calcite and its nucleation and growth are influenced by environmental parameters, such as carbon dioxide partial pressure, relative humidity and temperature.

TL;DR: In this article, concrete slabs uncovered at neolithic archaeological sites in southern Galillee were described, showing that Roman concrete and the Greek emplechton had their precursors in lime/pozzolan-bound mortar and plaster.
Abstract: The article describes concrete slabs uncovered at neolithic archaeological sites in southern Galillee. It shows that Roman concrete and the Greek emplechton had their precursors in lime/pozzolan-bound mortar and plaster. The binding properties of concrete were discovered early in human history. Burnt limestone was slaked in contact with moisture or rain, and the resulting powder was then found to have binding properties. Polished concrete floors have been excavated in Jericho. Neolithic lime preparation is described, as well as the laboratory investigation of excavated samples.

TL;DR: In this article, the authors studied the kinetics of the silicothermic reduction process of dolomite ore at a temperature range from 1150-1300 °C and found that the maximum reduction extent of about 92% was achieved when using charges in the form of briquettes containing 2.5 wt.% CaF2, CaO/MgO molar ratio of 1.6 and using silicon as reductant with its weight ratio/mgO equals 1.45.

TL;DR: In this article, the authors used a mixture of biomass ash and fired ceramic residue formed by crushing pieces of broken and defective ceramic products from a brick factory (chamotte) to obtain low-temperature structural insulation ceramics.

TL;DR: The radio-opacity of the resulting cement was three times greater than that of cortical bone because of the presence of strontium ions, a feature that complies with the requirements for vertebroplasty.
