Special Issue Information

Dear Colleagues,

The benefits of recycling in the construction sector have been widely demonstrated and are unquestionable. The advances in the use of recycled aggregates, steel slags and low-impact cements imply an important reduction of the environmental footprint, and eco-efficient concretes made with them must be a priority. However, these materials show in some cases losses of mechanical and durability behavior compared with natural materials. This is why we must invest our efforts on finding high-performance eco-efficient concretes that can compete or even surpass traditional concrete. To achieve this, the research and dissemination of their results is essential. The objective of this Special Issue is to group the most recent and relevant research in relation to high-performance eco-efficient concrete into a single document. Subsequently, the possibility of publishing a book with the contributions of all authors will be assessed.

This Special Issue is therefore dedicated to “High-Performance of Eco-Efficient Concrete, Volume 3”, and it intends to welcome contributions regarding, but not limited to, the following subjects:

  • High-performance eco-efficient concrete using recycled aggregates;
  • High-performance eco-efficient concrete using slags;
  • High-performance eco-efficient concrete using low-impact binders;
  • Mechanical behavior of high-performance eco-efficient concrete;
  • Durability of high-performance eco-efficient concrete;
  • Rheology of high-performance eco-efficient concrete;
  • Permeability of high-performance eco-efficient concrete;
  • Fatigue behavior of high-performance eco-efficient concrete;
  • Behavior of high-performance eco-efficient concrete in aggressive environments;
  • Structural design of high-performance eco-efficient concrete;
  • Life cycle assessment of high-performance eco-efficient concrete.

Durability and Abrasion Resistance of Innovative Recycled Pervious Concrete with Recycled Coarse Aggregate of Different Quality under Sulfate Attack

Construction and demolition wastes (C&DWs) have raised a large number of ecological and environmental problems. Recycling C&DWs into arecycled concrete aggregate (RCA) will help save natural resources effectively and reduce the negative impact of C&DW on the environment. Innovative pervious concrete (IPC) can mitigate extreme weather disasters, such as rainstorms, and overcome the low strength and poor durability of traditional pervious concrete. In this study, innovative recycled pervious concrete (IRPC) is prepared by combining RCA with IPC, which has broad application prospects and ecological friendliness. This study investigates the effect of RCA quality grades and replacement rates on the mechanical property, permeability, sulfate resistance and abrasion resistance of IRPC. IRPC mixtures were prepared with three different quality grades (high, medium and low qualities) of aggregates named as NA, RCA1 and RCA2. Moreover, the replacement rate of RCA for NA varied as 0%, 25%, 50%, 75% and 100%. The IRPC specimens were tested for compressive strength, mass loss and abrasion resistance after different sulfate wetting-drying cycles of 0, 30 and 60. The results exhibited that the initial compressive strength of all types of IRPC was more than 40 MPa. The compressive strength and mass of most IRPC increased first and then decreased slightly with the passage of a number of sulfate wetting-drying cycles, indicating IRPC has good resistance to sulfate attack. Sulfate attack and the addition of RCA will reduce the abrasion resistance of IRPC. However, when the replacement rate is lower than 50%, and the RCA quality is better (attached mortar content < 25%), the abrasion resistance of IRPC will be improved under sulfate attack. The experimental results might be useful as a reference and design methodology for employing IRPC in pavement applications in the future. Full article

The high consumption of natural resources in the industrial sector makes it necessary to implement measures that enable the reuse of the waste generated, seeking to achieve circular economy. This work assesses the viability of an alternative to the use of CEM III B 32.5 R cement in mortars for the internal coating of centrifugally spun cast iron pipes for water piping. The proposal is to reuse the slag generated in the casting process after being finely ground, as an addition mixed with CEM I 52.5 R cement, which is basically Portland clinker. In order to analyse this possibility, an extensive experimental campaign was carried out, including the analysis of the cupola slag (micro-structural and chemical composition, leachates, setting time, vitrification, puzzolanicity and resistance to sulphate) and regarding the mortars (workability and mechanical properties). The experimental programme has shown that the optimum substitution is achieved with a replacement percentage of 20% of the cement, with which similar workability, superior mechanical properties and guaranteed resistance to sulphate attack are obtained. In addition, both economic and environmental savings are achieved by not having to transport or landfill the waste. In addition, the new cement is cheaper than the cement currently used. Full article
