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%,

Performance of Sintered Pozzolanic Artificial Aggregates as Coarse Aggregate Replacement in Concrete

2021
The abundant increase in waste quantities year by year and the depletion of natural resources worldwide are the major concerns among researchers. Recycling and reusing various types of natural or by-product material waste from industry become highlighted in the recent study.

New evidence of early use of artificial pozzolanic material in mortars

Journal of Archaeological Science, 2013
Hydraulic building composites, such as mortars and plasters, produced with artificial pozzolanic materials, became widely popular thanks to the Romans. Reports on earlier uses of such composites can also be found, mainly in archaeological and historic documents. These date back as far as the time of Minoan and Mycenaean civilizations.
