ALKALI-ACTIVATED BINARY CONCRETE BASED ON NATURAL POZZOLAN; A REAL AND ECO-FRIENDLY ALTERNATIVE TO THE OPC CONCRETE

Alkali-activated binary concrete based on natural pozzolan; a real and eco-friendly alternative to the OPC concrete

This research shows the obtaining and characterization of an Alkali Activated Binary Concrete (AABC), based on 70% of a natural volcanic pozzolan (NP) and 30% ground blast furnace slag (GBFS), as a real and environmentally sustainable alternative of replacement to the Portland cement (OPC)-based concrete.As the alkaline activator a mixture of sodiu

Postcranial heterochrony, modularity, integration and disparity in the prenatal ossification in bats (Chiroptera)

Abstract Background Self-powered flight is one of the most energy-intensive types of locomotion found in vertebrates.It is also associated with a range of extreme morpho-physiological adaptations that evolved independently in three different vertebrate groups.Considering that development acts as a bridge between the genotype and phenotype on which
