Characteristics and applications of some dolomitic rocks from Argentina Fecha: 01/01/2017Tipo de documento: Parte de libroResumen:Argentina is a vast territory with different geological settings. In this scenery, dolomitic rocks are abundant and widespread. The economic importance of both this lithology and the main mineral constituent (dolomite) is the first cause for the studies carried out on these types of rocks. Dolomitic rocks in Argentina have been exploited for hundre...2015
Asbestiform Amphiboles in a Serpentinite Quarry in Operation, Province of Córdoba, Argentina Fecha: 01/01/2015Tipo de documento: Parte de libroResumen:Active serpentinite quarries located in the province of Córdoba (Argentina) provide raw material for metallurgical and construction industries. In the studied Adita quarry, veins with asbestiform minerals occur at the contact between pegmatitic dikes and the serpentinized ultramdics. In the past asbestos have been used for decades, but nowadays th...2013
Basaltic rocks from Argentina used in concrete structures Fecha: 01/01/2013Tipo de documento: LibroResumen:Basaltic rocks have been widely used in several countries of South America for major engineering projects, such as the hydroelectric dam “Yacyretá”, built on the Paraná River, between Argentina and Paraguay. Moreover, basalts are very abundant in the Patagonia and participate in important amounts in most coarse and fine aggregates (gravel and...2010
Metamorphic rocks from Córdoba (Argentina) and the alkali-silica reaction Fecha: 01/01/2010Tipo de documento: Parte de libroResumen:The “Sierras Pampeanas de Córdoba” (Argentina) is an igneous-metamorphic complex affected by shear zones. The deformation varies from one sector to another producing microstructures that affect the internal order and the size of the crystals, generating sites susceptible to suffering the attack of alkaline solutions. This process, known as alk...Petrographic study of gravel used as concrete coarse aggregate in concrete in Patagonia Argentina Autores: -Maiza, Pedro Marfil, Silvina Andrea Fecha: 01/01/2010Tipo de documento: Parte de libroResumen:Gravels that are predominantly volcanic in composition cover a large area in Argentine Patagonia. They are frequently used as concrete aggregates. It is quite common to find pavements that are deteriorated due to the development of the alkali-silica reaction. ...
