Effectiveness of shrinkage-reducing admixtures on Portland pozzolan cement concrete
(CONSEJO SUPERIOR INVESTIGACIONES CIENTIFICAS-CSIC, 2005)
Drying shrinkage causes tensile stress in restrained concrete members. Since all structural elements are subject to some degree of restraint, (trying shrinkage is regarded to be one of the main causes of concrete cracking.
Impact of using lightweight eco-bricks as enclosures for individual houses of one story on zones of high seismicity

Control of hydration rate of polymer modified cements by the addition of organically modified montmorillonites
(Elsevier, 2013-03)
The addition of polyvinyl alcohol (PVA) in concrete causes a delay in the hydration rate of Portland cement paste. Three different montmorillonites (MMTs) (Cloisite Na, 30B, and Nanofil) were previously mixed with PVA in ...

Corrosion inhibition studies of the combined admixture of 1, 3-diphenyl-2-thiourea and 4-hydroxy-3-methoxybenzaldehyde on mild steel in dilute acid media
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Química, 2017-01-01)
Mild steel corrosion is responsible for economic and industrial losses due to accelerated deterioration. Synthesized derivatives of thiourea and phenolic aldehydes containing heteroatoms are capable of inhibiting corrosion ...

(Instituto Tecnológico de Costa Rica, 2015)
This paper proposes a project management plan for the implementation of the admixture’s business for the hydraulic concrete of Cemex Costa Rica S.A., based on the methodological framework for the Professional Administration ...
Isotopic fingerprints on lacustrine organic matter from Laguna Potrok Aike (southern Patagonia, Argentina) reflect environmental changes during the last 16,000 years
(Springer, 2009-06)
A combination of carbon-to-nitrogen ratios (TOC/TN), Rock Eval-analyses, and stable isotope values of bulk nitrogen (δ15N) and organic carbon (δ13Corg) was used to characterize bulk organic matter (OM) of a piston core ...
Differential gene expression by Paracoccidioides brasiliensis in host interaction conditions: Representational difference analysis identifies candidate genes associated with fungal pathogenesis
(Elsevier B.V., 2006-10-01)
Paracoccidioides brasiliensis causes infection by the host inhalation of airborne propagules of the mycelia phase of the fungus. These particles reach the lungs, and disseminate to virtually all organs. Here we describe ...
