The U.S. Geological Survey, in cooperation with the Colorado School of Mines and the U.S. Environmental Protection Agency, has demonstrated the application of pulsed limestone bed (PLB) treatment of acid mine drainage (AMD) at the Argo tunnel discharge near Idaho Springs, Colorado. Current technology for AMD treatment at the Argo facility is neutralization with lime. However, lime neutralizatio...

The Church of the Company Jesus in Quito (1605–1765) is one most remarkable examples colonial religious architecture on World Heritage List. This church has multiple constructive phases and several interventions with no clear record entire architectural site, including historical mortars. A total 14 samples coating mortars inside central nave were taken, protocols suggested by research team a c...

Abstract Consolidates based on Ca(OH) 2 have been prepared as macro- and/or nanoparticles dispersed in different alcohols, regardless of the precursor nature. Their efficiency is related to small dimensions particles and dispersion media, which allows their penetration into deteriorated material substrates, well an increased reactivity towards CO . Besides consolidating effect there a strong ne...

We develop multiscale mortar mixed finite element discretizations for second order elliptic equations. The continuity of flux is imposed via a mortar finite element space on a coarse grid scale, while the equations in the coarse elements (or subdomains) are discretized on a fine grid scale. The polynomial degree of the mortar and subdomain approximation spaces may differ; in fact, the mortar sp...

Lime treatment of wastewater sludge has been in use for over a century. This paper describes the use of ‘Liquid Lime’ and hydrated lime suspensions as a sludge treatment process for the specific purpose of agricultural recycling. The introduction of ‘Liquid Lime’ treatment has enabled South West Water to achieve full compliance with the Sludge (Use in Agriculture) Regulations at a time when the...

The mixture of olive oil and lime cream has been traditionally used to treat external burns in the region of Hatay/Antakya and middle Anatolia. Olive oil and lime cream have been employed by many physicians to treat many ailments in the past. A limited number of studies have shown the antibacterial effect of olive oil and that it does not have any toxic effect on the skin. But we did not find a...

The rheology of lime binders, which is critical in the final performance of lime mortars and plasters, is poorly understood, particularly in its relationship with the microstructure and colloidal characteristics of slaked lime (Ca(OH)(2)) suspensions (i.e., lime putties). Here, the contrasting flow behavior of lime putties obtained upon slaking (hydration) of soft and hard burnt quicklimes (CaO...
