Historic Mortars with Burned Alum Shale as an Artificial Pozzolan

, 2012
From the mid-eighteenth century extensive research in Sweden and in present day Finland focused on the development of mortars with hydraulic properties, the results mainly published by the Royal Swedish Academy of Science. The aim was to replace imported Italian pozzolan and Dutch trass with a pozzolan produced in Sweden.

Stabilisation of Urmia Lake peat using natural and artificial pozzolans

Proceedings of the Institution of Civil Engineers - Ground Improvement, 2022
Peat generally found in thick layers in limited areas such as Urmia Lake, Iran has low shear strength and high compressive deformation. Therefore, an appropriate soil improvement method is required. This paper presents an experimental study of the stabilisation of Urmia Lake peat on the Urmia–Tabriz highway, 7·8 km to the east of Urmia city in Iran. A

The Omani Artificial Pozzolans (Sarooj)

Cement, Concrete, and Aggregates, 2001
Abstract Sarooj is a local Omani term for artificial pozzolana produced by calcining clays. Calcined clay mixed with lime and water has been used as a cementing material for a long time. It has been used widely in hydraulic structures due to its good hydraulic properties and in military defensive installations due to its durability. This

Evaluation of pozzolanic activity of natural and artificial pozzolans by thermal analysis

Thermochimica Acta, 2004
Abstract In this research, the pozzolanic activity of natural and artificial pozzolan used for preparation of restoration mortars was evaluated. For this purpose, several pastes were prepared, by mixing two artificial pozzolans and a natural one with commercial hydrated lime, in different ratios. The pastes were cured in standard conditions (RH = 98%,
