In developing country like India due to the remarkable development in road infrastructure, Soil stabilization has become the major issue in construction activity. Stabilization is an unavoidable for the purpose of highway and runway construction, stabilization denotes improvement in both strength and durability which are related to performance. Stabilization is a method of processing available ...

Lead-acid batteries are commonly used as power sources for critical operations in the world. They find application air-traffic control towers, uninterruptible supplies (UPS), railroad crossings, military installations, hospitals, and weapons systems. also known automotive industrial batteries. consist of large amounts lead, sulphuric acid, plastics. The acid is tremendously irritant a carrier s...

In this study, the early-age strain–stress development of mixtures containing slag cement was measured on uniaxially restrained specimens using a specially designed testing frame starting right after casting. It was found that thermal deformation dominates early-age stress development in low w/cm and low slag cement paste systems. While for concrete, autogenous shrinkage is the major contributi...

Vitrification is considered to be an attractive technology for bottom ash treatment because it destroys the hazardous organics, contributes to immobilization of the heavy metals, and additionally it reduces drastically the volume. The main components of the vitrified bottom ash slag are SiO2 , CaO, Al2 O3 , Fe2 O3 , Na 2 O and MgO, and the compositions have direct effect on the glass formation ...

Argon oxygen decarburisation (AOD) slag may be used for phosphorus (P) removal, as its high pH and weatherable calcium (Ca) minerals provide sufficient Ca(2+) and OH(-) for calcium phosphate (Ca-PO4) precipitation. This study examined the P removal performance of AOD slag for use as wastewater treatment material. Batch experiments were carried out using both synthetic P solution and real wastew...

A new process route for the valorization of BOF steel slags combining H2 production and CO2 mineral sequestration is investigated at 300°C (HT) under hydrothermal conditions. A BOF steel slag stored several weeks outdoor on the production site was used as starting material. To serve as a reference, room temperature (RT) carbonation of the same BOF steel slag has been monitored with in situ Rama...

The industrial solid waste recycling team at North Minzu University has done much research on resource utilization of magnesium slag. This chapter mainly introduces a discussion includes the use slag to prepare glass ceramics, porous and sulfoaluminate cement clinker, fixing/stabilizing heavy metals in acidic residue generated by lead-zinc smelting, modifying copper

In this study, slag penetration into a magnesia refractory monolithic was investigated by the crucible test method. A synthetic calcium aluminate slag system has been used to study commercial magnesia mix refractory for 1, 2, 3, 4, 5 and 6 hours at 1450°C and 1600°C. It has been shown that the penetration rate is controlled by a diffusion mechanism at 1450°C. In this case, capillaries are the ...

The contribution made by orbiting solid rocket motors (SRMs) to the orbital debris environment is both potentially significant and insufficiently studied. A combination of rocket motor design and the mechanisms of the combustion process can lead to the emission of sufficiently large and numerous by-products to warrant assessment of their contribution to the orbital debris environment. These par...
