Non-destructive screening methodology based on handheld XRF for the classification of concrete: cement type-driven separation

The utilization of locally available concrete waste for producing recycled concrete aggregates is recognized as one of the most sustainable ways of satisfying the growing demand for concrete production. However, the quality of concrete waste depends on its origin and it may significantly differ from one concrete structure to another. Knowing the...

An evaluation of the ice melting during concrete-ice abrasion experiment

The process of ice melting during abrasive interactions with concrete is essential in a variety of contact phenomena. In this paper, we refer to abrasive tests for different samples of concrete with roughness in the range of 9–35 μm. The experimental conditions were: 1 MPa ice pressure, ambient temperature −10 °C, average sliding velocity 0–0.16...

Making bioreceptive concrete: Formulation and testing of bioreceptive concrete mixtures

Increased urbanisation will put an increasing strain on our green spaces, which is expected to have a significant effect on our physical and mental health, as well as the health of our ecosystems. As such it is important to integrate more green spaces in our urban fabric. One way of doing this is by making use of so-called bioreceptive concrete...

Bond strength of cementitious screeds on concrete bearing floors

In this study the cracking and debonding behaviour of cementitious screeds bonded to concrete bearing floors is <br/>analysed. In order to obtain insight in this behaviour research is performed to the surface tensile strength of concrete, <br/>the bond strength of screeds on concrete bearing floors, the behaviour of screeds during shrinkage and...
