“…La incorporación de residuos de polvo de trituración es viable para la elaboración de HAC con propiedades aceptables en estado fresco y endurecido (Mahalingam B. et al (2018)). Esto da lugar a un hormigón más sustentable con un residuo de bajo costo (Dobiszewska M. (2017)).…”

Un hormigón autocompactante requiere elevados contenidos de material fino para mantener la estabilidad de la mezcla, garantizando una elevada fluidez y una moderada viscosidad. El objetivo del trabajo es analizar la viabilidad de utilización del polvo de basalto (PB) como material suplementario al cemento Portland para proveer la cantidad adecuada de partículas finas en pastas autocompactantes como la primera fase del diseño de morteros y hormigones. Se caracterizaron muestras de PB provenientes de cuatro canteras de la Provincia de Misiones con el fin de utilizarlas en la elaboración de pastas con un cemento Portland compuesto. El estudio de las pastas abarcó la determinación del escurrimiento con cono de Kantro y la velocidad de flujo en cono de Marsh. Los resultados indican que es viable la utilización del PB desde el enfoque de autocompactabilidad, teniendo en cuenta que la relación entre agua y material fino es determinante en el diseño de la mezcla, afectando principalmente la demanda y el punto de saturación del aditivo y la fluidez y viscosidad de las pastas autocompactantes con diferentes porcentajes de reemplazo con PB. La resistencia a compresión de las pastas evaluada a 28 días varió entre 55 y 25 MPa para reemplazos crecientes de PB de 20 a 50%, respectivamente.Palabras claves: fluidez, pasta autocompactante, polvo de basalto, viscosidad.

“…The most commonly used non-pozzolanic filler is limestone powder. However, other non-pozzolanic fillers have been utilized such as marble dust, ceramic waste powder [12], quarry dust [13][14][15][16], and olive residue biomass fly ash [17].…”

The utilization of fine powders as fillers in self-compacting concrete (SCC) application is widespread, particularly in Europe. The incorporation of these fillers to attain the self-compatibility properties of SCC seems to be cheaper than the use of chemical admixtures. Among the wide range of potential fillers, dolomitic powders, particularly generated as by-products from quarry’s processing, are locally available and can be used to produce SCC. Few studies have shown that dolomitic powders can be incorporated in the SCC’s mix design, resulting in acceptable fresh and hardened properties of SCC. The particle size distribution and fineness of the dolomitic powder as well as the level of addition are the key factors affecting those properties. The influence of the chemical nature of the dolomitic powder on the properties of SCC, particularly the durability (e.g. alkali-carbonate reaction), is yet to be investigated. Furthermore, more efforts are still required to investigate the use of dolomitic by-products in the production of SCC.

“…However, the possibility of combining high spreadability in the absence of segregation with a rapid set of strength, with increased water resistance and frost resistance as well as resistance to aggressive environments is a distinctive feature of self-compacting concrete (SCC). These properties are achieved by careful selection of the granulometric composition of the mixture, the high quantity of the powdered component and the use of highly effective superplastizer [10,11]. The first approaches to the design of SCC compositions mainly focused on the selection of the water-binder ratio of cement paste and the amount of superplasticizer to achieve the required performance of technological properties.…”

Quantitative parameters of influence of grain composition of ground quartz sand and its quantity on the workability and segregation of self-compacting fresh concrete were determined at the constant amount of mixing water and water-cement ratio. Ground quartz sand in the amount of 50-150 kg/m3 was added instead of fine and coarse aggregates with changing the amount of polycarboxylate superplasticizer. It is stated that the use of ground quartz sand of finer grinding provides higher values of workability at the same quantity of water and superplasticizer. Segregation of the fresh concrete occurs when using increased amount of ground quartz sand of coarser grinding and increased amount of superplasticizer. Experimental studies have shown the effectiveness of the use of ground quartz sand to obtain self-compacting fresh concrete of different classes of workability SF1 and SF2 as well as classes of segregation resistance SR1 and SR2. The results of the experiments allow to state that the use of ground quartz sand of coarser grinding leads to segregation of fresh concrete at its low workability, while the use of ground quartz sand of finer grinding allows to obtain fresh concrete with resistance to segregation.
