The use of alkali-activated materials to produce concrete is a promising technology. However, information on the optimum curing regime required to maximize the performance of such concrete is lacki...

The flexural performance of steel fiber-reinforced concrete made with recycled concrete aggregates (RCA) and desert dune sand was investigated. Natural aggregates were replaced by 30, 70, and 100% ...

Alkali activation of fly ash and ground-granulated blast-furnace slag (GGBS) is a sustainable technology that promotes recycling of industrial by-products in the form of geopolymer composites. In t...

The increasing use of pervious concrete as sustainable and environment-friendly paving materials is primarily owed to its ability to reduce pavement runoff. The mechanical and transport properties of pervious concrete with 50% ground-granulated blast furnace slag (GGBS) replacement were examined. Open-graded 10 and 20 mm aggregates were used to attain porosity of 10%, 15%, and 20%. Polypropylene short-cut fibres were added to the mix. The clogging potential of pervious concrete exposed to dust was investigated. The results indicated that increasing the porosity led to a decrease in compressive and tensile strength. The fibre addition was effective in low-porosity concrete. Permeability was proportional to porosity and inversely proportional to aggregate size. After 40-year simulated dust exposure, the concrete permeability could be restored with the water flushing maintenance process. In comparison to Ordinary Portland cement concrete, pervious concrete incorporating GGBS is a more sustainable paving solu...
