Drilling muds commonly use organic polymers as viscosifiers or mud filtrate reducers. While these polymers are effective, they are also costly, contributing to higher operational expenses in oil well drilling. They play a crucial role in the success of drilling operations and help enhance various properties, particularly rheological characteristics. Due to environmental concerns, these polymers have become essential in water-based drilling fluids, serving as alternatives to oil-based muds. The present study aims t...

Alfa fibers have been investigated as a sustainable and cost-effective alternative to conventional reinforcement materials such as glass and carbon fibers, which are significantly more expensive and substantially increase the overall cost of mortar production. The present study aims to provide a comprehensive comparative analysis of mortars reinforced with different types of fibers, including mechanically extracted Alfa fibers, chemically treated Alfa fibers, and commercial polypropylene fibers. Fiber-reinforced m...

In order to valorize our natural resources especially dune sand, the physical and mechanical properties of adhesive mortars based on local mineral additions, have been studied in this present work. The experimental study was carried out on various adhesive mortars made with different contents of dune sand by partial substitution of cement. Adhesive mortars were made from Portland cement (PC; at 35%, 30% and 25%wt), Dune Sand (DS; at 60%, 65% and 75%wt), fillers and redispersible polymer powder (RDP; at 0.6%, 1.0% ...

Recently, nanotechnology has attracted a considerable scientific interest due the potential new uses of non-particles, which can improve the properties of cement mortars or concretes, such as Nanosilica. Nanoparticles, like those of nanosilica, have been shown to have unique physical and chemical properties different from those of conventional cement additions. Nanosilica was used either to replace part of the cements or as an addition to improve the performance of the cement such as accelerating the hydration of ...

Disposal of waste generated by the industries remains one of the major challenges to preserve the environment. Indeed, the use of industrial waste and by-products in construction is an important advantage to conserve natural resources. For this reason, several studies have focused on the use of marble waste in construction as recycled aggregate or fine powder. The work aim is to investigate the physical properties and mechanical behavior of eco-friendly mortar made with marble powder. The experimental study consis...

This study aims to valorise the mineral wastes in particular glass wastes, brick wastes and clay to produce granulated foam glass at different characteristics (G1: Granulate foam glass without additive; G2: Granulate foam glass with 10% clay and Granulate foam glass with 10% Brick wastes). The aggregates of foam glass were manufactured at a temperature 850 пїЅ C from glass wastes (cullet), brick wastes, clay and limestone as a foaming agent. Mixtures of Self-compacting mortar have been developed with elaborated fo...

The foundry sand wastes (FSW) are likely to constitute as raw material for the manufacture of cement mortars or concretes at a low cost. For this reason, present work has main objective to use the foundry sand wastes in self-compacting mortar as a fine aggregate (by a partial sand substitution). An experimental tests were carried out to evaluate fresh (slump test) and hardened (bulk density, compressive and flexural strength and elastic modulus) properties of SCMs based on FSW. The Natural Sand (NS) is substituted...
