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 “Advances in High-Performance Eco-Efficient Concrete”, 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.

Crack Width and Propagation in Recycled Coarse Aggregate Concrete Beams Reinforced with Steel Fibres
Appl. Sci. 2020, 10(21), 7587; https://doi.org/10.3390/app10217587 - 28 Oct 2020

Reducing the crack width is a vital feature for protecting rebars from corrosion. In this investigation, the impact of steel fibres (SFs) on the cracking of recycled coarse aggregate reinforced concrete (RCARC) beams was investigated. Twenty-seven reinforced concrete (RC) experimental samples (150 mm × 200 mm × 1500 mm) were manufactured. Shear rebars were considered with different spacings. Specimens were tested under a four-point flexural setup. Recycled coarse aggregate (RCA) from a destroyed building was employed at 0%, 50% and 100% by weight. SFs were added at three contents (0%, 1% and 2%) in order to reduce the crack width. The mid-span load–displacement relationship and the crack propagation and width were measured during the tests. Therefore, this study intended to assess the impact of utilising RCA and natural coarse aggregate on cracks’ spacing and propagation in RC beams when SFs were employed. The obtained outcomes were compared with the requirements of CSA S474, NS 3473E, EC2-04, CEB-FIP and ACI 224R-01. It was found that enough shear rebars should be provided through the beams to control the crack width and propagation, but that SFs enhanced the bending performance of RCARC with no shear rebars.

The research presented in this article analysed the influence of incorporating precast concrete waste as an alternative to coarse aggregate in self-compacting concrete to generate new precast elements. The experimental study involved the characterization of recycled aggregate and the design of the mix of the new self-compacting concrete (SCC). The experimental study evaluates the physical processes that affect the durability of concrete with percentages of incorporation such as 20%, 50% and 100% of recycled aggregate. Two types of SCC were manufactured with minimum compressive strength of 30 MPa and 45 MPa. The properties analysed were density of hardened SCC, shrinkage cracking, freeze-thaw resistance, resistance to ageing by thermal shock and abrasion resistance. The results obtained were compared with those of the control concrete, observing great capacity of the SCC under physical aggressions that affect durability. The results of this research show that it is possible to use the recycled aggregate coming from precast pieces in order to the manufacture of self-compacting recycled concrete in the same precast industry. However, high loss of proprieties occurs for a 100% substitution, while for 20% and 50%, the variations with respect to control concrete are smaller. In addition, taking advantage of this waste to incorporate it back into the production chain contributes to more sustainable construction. Full article

Rubber aggregates produced from waste rubber materials and environmentally friendly basalt fibers are excellent concrete modification materials, which significantly improve the working performance and mechanical properties of concrete. This paper studied the influences of water-binder ratio, basalt fiber content and rubber content on the properties of rubber-basalt fiber modified concrete (RBFC). Based on the response surface method (RSM), optimization schemes of three preparation parameters were designed. The results showed that all preparation parameters have significant impacts on the slump. The rubber content has a closer relationship with the compressive strength and the quadratic term of the basalt fiber content has a significant impact on the flexural strength. According to the analysis, the optimal mix ratio which possesses reliable accuracy compared with experimental results includes a water-binder ratio of 0.39, a basalt fiber content of 4.56 kg/m3 and a rubber content of 10%, Full article
