Due environmental problems related to Portland cement consumption, many studies have been performed to diminish its use. One solution is the development of alkali-activated binders, which can decrease CO2 emissions and ...

This study aimed to investigate the mechanical and durability properties of recycled aggre-gate concrete with a ternary binder system and optimized mix proportion. Two concretebatches were developed using a densified mix ...

This study aimed to investigate the mechanical and durability properties of recycled aggregate concrete with a ternary binder system and optimized mix proportion. Two concrete batches were developed using a densified mix ...

Alkali-activated binders are the new trend in building construction studies due their good mechanical properties and environmental advantages. These type of binders are obtained by a mixing of a solid precursor with an ...

This paper focuses on the reformulation of the internal functions of the performance-dependent failure criterion (PDFC) for concrete, proposed by the authors, and its validation for different concrete qualities and stress ...

The degradation of reinforcing concrete structures reflects in economic and environmental factors. Thus, the desire to minimize it motivates recent research, which aims to add nanomaterials to the cement matrix, seeking ...

A range of MgO and SiO2 blends mixed with water are analyzed to develop clinker-free fiber-cement products reinforced with cellulosic fibers. The target is the development of a binder which is not chemically aggressive to ...

The advance of civil construction, linked to the growth of the ceramic products market, stimulates the production of adhesive mortars that are used in settling ceramic plates. NBR 14081-1 (ABNT, 2012) classifies mortars ...
