Rheological behavior and compressive strength of concrete made with recycled fine aggregate of different size range

Biao Li et al.

Summary: This study examined the rheological properties and compressive strength of concrete containing recycled fine aggregate (RFA) with different particle size ranges. The results showed that the developed polycarboxylate superplasticizer was more compatible with RFA and different particle size ranges of RFA had a clear impact on the compressive strength of concrete.

Development and statistical database analysis of hardened concrete properties made with recycled concrete aggregates

Anuruddha Jayasuriya et al.

Summary: The study analyzed a database of mechanical properties of concrete containing coarse RCA from 115 peer-reviewed journal articles, and explored how mixture design proportions influence RCA concrete hardened properties through sensitivity study and full-factorial analysis. The results showed that the compressive strength of concrete is impacted by the level of RCA replacements, but adequate concrete strengths for various applications can be achieved at all replacement ratios.

Recycling hazardous water treatment sludge in cement -based construction materials: Mechanical properties, drying shrinkage, and nano-scale characteristics

Zhi-hai He et al.

Summary: This study investigates the impact of modified water treatment sludge on the composition and performance of Portland cement composites. It was found that when 10% of the cement was replaced by modified sludge, higher compressive strength was achieved. The modified sludge exhibits pozzolanic activity, improves the compactness of the microstructure, and reduces drying shrinkage.

Experimental study on full-volume slag alkali-activated mortars: Air-cooled blast furnace slag versus machine-made sand as fine aggregates

Jinyan Shi et al.

Summary: The study showed that as the substitution rate of ACBFS increased, the flowability and mechanical properties of FSAM significantly improved. Furthermore, the addition of ACBFS also helped enhance the compactness of the mortar's microstructure, thus improving the impermeability of FSAM. Additionally, specimens mixed with ACBFS exhibited good high temperature resistance due to the porous feature of the aggregate.
