Mortarless masonry can facilitate faster construction of walls over conventional mortared masonry due to the absence of a mortar laying process and availability of interlocking features on the blocks. The structural performance of mortarless masonry can be improved by grouting and providing reinforcement in hollow cores of the interlocking blocks. ...

Carbonation can be a major aging process during disposal of alkaline cementitious waste forms and can impact constituent leaching by changes in material alkalinity, pore structure, and controlling mineral phases. The effect of carbonation on the leaching of major and trace constituents from Cast Stone, a cementitious waste form developed to treat h...

It is widely recognized that today people around the world still admire the Egyptian civilization and wonder how Egyptians came to manufacture mortar. The present work aims to study the construction materials that were used in ancient Egypt and their development over time. To do this, it was decided to first evaluate the physical and mechanical per...
Due to an increasing amount of aging tendencies in Swedish embankment dams, failures such as internal erosion has become a more common problem. Internal erosion is a phenomenon where certain soil material within the embankment dam is removed, often over a longer period of time. It is most common to occur at the inner core of the dam, and if it is a...
Knowledge of the thermal behaviour around and throughout borehole heat exchangers (BHEs) is essential for designing a low enthalpy geothermal plant. In particular, the type of grout used in sealing the space between BHE walls and the pipes is fundamental for optimizing the heat transfer and minimizing the thermal resistance, thereby promoting the r...

The main objective of this work is to highlight experimentally the effect of quarry waste limestone fillers (LF) on the rheological properties of concrete. All mixtures were made with water-to-cement ratio (W/C) of 0.50. The method adopted based on the rheological behavior of concrete incorporating LF as a partial substitute for sand in multi-scale...
Les matériaux alcali-activés apparaissent comme une alternative potentielle aux liants hydrauliques classiques dans plusieursapplications en génie civil, pour répondre à des enjeux techniques et environnementaux. Néanmoins, ces matériaux n’ont pas étésuffisamment explorés dans le domaine du renforcement des sols. Cette thèse a pour but d’évaluer le...

The role of sulfate ions on corrosion of steel in alkaline solutions (including cementitious materials) has been contested in the literature due to the effects of the many exposures, material and test conditions. Recent observations of steel corrosion in cementitious grouts in post-tensioned bridges coinciding with elevated sulfate-ion concentratio...

In the present project two series of laboratory tests were performed. The first series aimed at investigating the feasibility of using waste mussel shells as aggregates in the production of concrete. Specimens were prepared by using various types of cements and shells of different size. Their 28-day unconfined compressive strength and stress-strain...
