“…Concrete with slag shows superior resistance to chloride penetration (Yildirim et al 2011). Cement type, W/B and curing condition are very influential factors concerning chloride penetration (Song et al 2008;Guneyisi et al 2009;Yildirim et al 2011). For low W/B, even though air permeability differs largely between curing conditions, D a show less difference.…”

Assessment of concrete cover quality is necessary for proper maintenance of concrete structures. Concrete durability is evaluated primarily based on chloride penetrability, neutralization and other external factors. The present study attempts to analyze concrete quality and its mass transfer resistance performance by measuring the air permeability and its relation with concrete durability indicators like chloride diffusion and neutralization. The applicability of air permeability as a durability indicator is validated using concrete with different materials, parameters and curing conditions. The tests are conducted on laboratory prepared concrete as well as for concrete exposed to actual marine conditions. From the experimental results, it is found that air permeability coefficient, neutralization coefficient and chloride ion diffusion coefficient have high correlation. It is suggested that air permeability could be considered as an alternative to estimate mass transfer resistance of concrete and as a concrete durability indicator.

“…Los valores experimentales obtenidos por los hormigones reciclados ensayados en este trabajo fueron similares a los obtenidos por Yildirim (Yildirim, Ilica & Sengul, 2011), donde el hormigón patrón fabricado con un cemento I 42,5R y una relación agua-cemento de 0.45, habiendo realizado los ensayos en las mismas condiciones, obtuvo una resistividad de unos 12 kOhm.cm (similar valor obtenido por HP) y unos 24 kOhm.cm en el hormigón con cenizas volantes, mejorando considerablemente la resistividad del hormigón tal y como se ha demostrado en este trabajo.…”

“…En todos los hormigones evaluados, los valores experimentales estaban por encima de los encontrados en la bibliografía, posiblemente debido al empleo de un cemento de menor resistencia (P-35 MPa) en comparación con el cemento I 42.5R mayoritariamente utilizado. Tal y como demuestra Yildirim (Yildirim, Ilica & Sengul, 2011), existen grandes diferencias en esta propiedad cuando se cambia el tipo de cemento o se emplea alguna adición.…”

An experimental investigation was carried out to enhance the properties of two‐stage concrete, also known as preplaced aggregate concrete (PAC), by adding ground granulated blast furnace slag (GGBS) and silica fume (SF) as partial replacement of cement at different proportions. PAC was produced using the gravity process by first placing the coarse aggregates into the formwork and then injecting a grout to fill in the voids in‐between the aggregates. Partial replacement of cement by GGBS and SF at 30 and 10%, respectively were found to be a suitable mix for PAC. Even though incorporation of GGBS and SF increased the shrinkage, strength and durability were improved. Generally, shrinkage produced by PAC was significantly lower than that of conventional concrete. By applying preplaced aggregate with an improved composition of grouts, properties of concrete, like strength and permeability, can be enhanced with shrinkage kept within an acceptable level.
