The aim of this research is to reduce the number of defects caused by the hydrophobicity of silica aerogel (SA) in the interfacial transition zone formed by this solid aggregate and a liquid binder in an alternative construction composite (paste). A new technique for controlling compatibility issues has been developed by modifying the chemicals and...

This research presents a rheological characterization approach to assess the suitability for pastes of alkaline-activated cements of metakaolin and limestone for its potential application in 3D printing. This evaluation was based on the influence of the chemical composition; therefore, an experimental design was used in which the factors were the r...

This work evaluated the mechanical behavior of FDM-printed parts of virgin (v-PLA) and recycled PLA (r-PLA) based on a factorial design, with ultimate tensile strength (UTS) as the response variable and PLA type, geometric pattern (linear, tridimensional, and hexagonal), and infill percentage (33%, 66%, and 100%) as factors. The v-PLA results showe...

This study evaluated the flow behavior of Portland cement mortars incorporating basalt microfibers (BFRM). The research focused on the development of a mathematical model to predict flow properties in BFRM based on the water-to-cement (w/c) ratio, sand-to-cement (s/c) ratio, and basalt microfibers percentage (%BF). Three sequential experimental des...

Los modelos convencionales de producción en la industria del cemento y el concreto (ICC) asocian problemas ambientales importantes; por otro lado, existen tecnologías emergentes que podrían disminuirlos. No obstante, se requiere del enfoque multidimensional de la economía circular para orientar el desarrollo sostenible de manera perdurable, modelan...

The mechanical characteristics and properties of 3D printed parts are highly influenced by the printing parameters, the printer characteristics, the raw material and the capabilities of the G-code generating software. This work is distinguished by presenting a systematic study to optimize the mechanical properties of PLA, ABS and Nylon + carbon fib...

This study examines the systematic decrease of concrete compressive strength with rubber scrap from the hydration reaction point of view. The work was focused on the determination of the hydration rate equation of normal, catalyzed, and rubberized Portland cement pastes. The basic idea was to prove the inhibiting effect of zinc compounds from rubbe...

The incorporation of triturated tire particles as an aggregate in the concrete mixture is one of the ways to take advantage of this Waste Rubber (WR) in order to improve concrete properties, such as mechanical behavior. In this research we evaluated mechanical behavior of concrete specimens prepared with different amounts WR, which partially substi...

Currently, the use of waste materials in Portland cement mixtures and the reduction of the use of clinker is important due to environmental issues. One of the waste materials of importance for the scientific community is end-of-life tires, because there are millions of tires in landfills; however, there are other materials in similar circumstances...

Severe plastic deformation Mechanical behavior Pitting corrosion a b s t r a c t The pitting corrosion of an aluminum alloy AA1050 after being processed by continuous closed die forging (CCDF) was evaluated by cyclic potentiodynamic polarization (CPP). Microstructure evolution, mechanical and corrosion behaviors were studied as a function of the to...

Se estudió la evolución microestructural, el comportamiento mecánico y a la corrosión del Al1050 procesado por Forja Continua de Matriz Cerrada (FCMC) con 0, 16 y 24 pases, manteniendo la carga por 10 y 15s. El estudio EBSD revela un refinamiento de Grano Ultrafino (GUF) de 0.78µm a los 24 pases en una zona altamente deformada; lo cual justifica el...
