This study includes the effect of lime addition on engineering properties gypseous soil taken from a part Najaf- Karbla plateau (52, 48, 72% gypsum). Also this shows increase in proportion gypsum northwest direction area. Maximum dry density and optimum moisture content (2.065, 2.025 2.003) at 15%, 14% 15% respectively for three samples. The maximum decrease while increases with increasing rati...

this paper describes the results of a study which was primarily directed to the determination of geotechnical properties of fine and coarse grain soils stabilized by lime obtained from taleghan, northwest of tehran to assess its suitability as construction material. soils were treated with lime mixtures in various portions between 3 to 9 percents by weight. the samples were cured for different ...

The paper focuses on the improvement of clayey soil (A-6) with locally available and cheap modifiers, in terms stiffness behavior weak subgrade for flexible pavement. modifiers used include lime (hydrated), marble waste sand. specimens underwent triaxial testing Clegg impact testing. Triaxial involved assessment resilient modulus (MR) using Impact Hammer. According to study, proved be most infl...

Although Portland cement is the most widely used binder in the stabilisation/solidification (S/S) processes, slag-based binders have gained significant attention recently due to their economic and environmental merits. In the present study, a novel binder, reactive MgO activated slag, is compared with hydrated lime activated slag in the immobilisation of lead and zinc. A series of lead or zinc-...

Abstract The impact of dewatering on lime mortars modified using brick dust was studied, as it is particular importance in conservation applications. Dewatering takes place when freshly mixed come into contact with a porous substrate, such or stone, during site construction. Since the process between mortar and its substrate can modify properties, understanding enables pozzolan-modified hydrate...

There have been several emphasized pathways toward a reduction in carbon footprint the built environment such as recycling, technologies with lower energy consumption, and alternative materials. Among materials, bio-based materials nature inspired solutions well-received. This study examines merits of using rice husk ash replacement for lime; lime has high mainly associated decomposition calciu...

A higher bustle temperature in midrex direct reduction process is always desirable due to its positive effect on the productivity and DRI quality. The limit of the bustle temperature is related to the sticking or clustering behaviour of oxide pellets during the reduction in the reactor. It has been well estabilished that coating of oxide pellets by a refractory material decreases its&#10tendenc...
