What is it about?
This study evaluated the durability properties of self-compacting concrete made with recycled aggregate for pavement application. The developed mixture was subjected to permeability, water absorption, and chloride penetration tests, and obtained results were compared with those of normal pavement concrete. Three recycled concrete aggregates (RCA) replacement percentages at the rate of 20%, 40%, and 60% were considered in addition to the control concrete (0%). A grade M40 grade ternary blended concrete with Ordinary Portland cement (OPC), fly ash, and silica fume was designed. The fresh properties of the concrete - slump flow and V-funnel flow tests were determined. The results showed that a mixture containing up to 40% RCA had higher resistance to water absorption and chloride ingress than a similar mixture for normal-weight concrete.

Perspectives
I hope this article makes what people might think is a boring, slightly abstract area like health economics and measuring things like health, kind of interesting and maybe even exciting. Because the way we spend money on health and social care is not just a problem for politicians, managers and researchers to worry about - it is an issue that touches every single human being on this planet in one way or another. More than anything else, and if nothing else, I hope you find this article thought-provoking.
