Concretes with Calcined Clay and Calcined Shale: Workability, Mechanical, and Transport Properties
(American Society of Civil Engineers, 2020-05-30)
This paper analyzed the eco-efficiency of concretes (water/cement ratio = 0.50; cement content=350 kg/m3, and slump = 7 cm) with blended cement containing 25% by weight calcined pozzolan obtained from a low-grade kaolin ...
Implicancias tecnológicas del uso del yeso y la cal en el arte rupestre de La Tunita (departamento Ancasti, provincia de Catamarca): aportes a través de la experimentación con mezclas pigmentariasTechnological implications of the use of gypsum and lime in the rock art of La Tunita (Ancasti department, Catamarca province): contributions through experimentation with pigment mixtures
(Universidad Nacional del Centro de la Provincia de Buenos Aires. Facultad de Ciencias Sociales, 2021-07)
Este trabajo presenta la labor experimental realizada en el marco del estudio de las mezclas pigmentarias de las pictografías rupestres del alero de La Sixtina y la Cueva del Hornero en el complejo de sitios La Tunita ...
On Bézout inequalities for non-homogeneous polynomial ideals
(Academic Press Ltd - Elsevier Science Ltd, 2021-09)
We introduce a “workable” notion of degree for non-homogeneous polynomial ideals and formulate and prove ideal theoretic Bézout inequalities for the sum of two ideals in terms of this notion of degree and the degree of generators.
Water absorption of fine recycled aggregates: effective determination by a method based on electrical conductivity
(Springer, 2018-10)
The high absorption of fine recycled aggregates is indicated as the main difference with respect to fine natural aggregates. This property determines the extra amount of water to be added during mixing to avoid a loss in ...
Discussions about the landscape of possibilities for treatments of cosmic inflation involving continuous spontaneous localization models
(Springer, 2020-11)
In this work we consider a wide variety of alternatives opened when applying the continuous spontaneous localization (CSL) dynamical collapse theory to the inflationary era. The definitive resolution of many of the issues ...
Degradation of dichloroacetic acid in homogeneous aqueous media employing ozone and UVC radiation
(Royal Society Of Chemistry, 2011-04)
A tentative workable mechanism for dichloroacetic acid decomposition (DCA) in aqueous media employing ozone and UVC radiation has been developed. All experiments were made in a homogeneous medium under assured kinetic ...
Assessing biochar impact on earthworms: Implications for soil quality promotion
(Elsevier Science, 2019-03)
Potential harmful effects of spent coffee grounds (SCGs)-derived biochar on earthworms (Lumbricus terrestris) were investigated through two complementary experiments, which assessed the avoidance response of earthwormsto ...
Improving Technological Performances of Ball Clays: A Case-study from Patagonia (Argentina)
(Goller Verlag Gmbh, 2011-07)
Innovation in the ceramic tile industry is stressing properties like powder flowability and ability to toughen green tiles, so turning technological requirements of ball clays ever stricter in terms of plasticity, dispersion ...
Portland blended cements: Demolition ceramic waste managementCementos Portland con adiciones: manejo de residuos cerámicos de demolición
(Instituto de Ciencias de la Construcción Eduardo Torroja, 2017-01)
Demolition ceramic wastes (DCWs) were investigated in order to determine their potential use as supplementary cementitious materials in Portland Blended Cements (PBCs). For this purpose, three ceramic wastes were investigated. ...
