What does this research mean for the field?

In underwater engineered cementitious composites, fly ash and ground granulated blast-furnace slag binders provide superior fresh-state stability and hardened mechanical performance, whereas high-volume coral powder substitution degrades stability, tensile performance, and pore structure. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

Investigate how varying binder proportions of fly ash, ground granulated blast-furnace slag, and coral powder impact the fresh-state stability, mechanical properties, and microstructure of underwater engineered cementitious composites.

Overview

Experimental study reveals that slag and fly ash optimize anti-washout stability and ductility in underwater engineered cementitious composites, highlighting viable binders for marine construction.

Key Points

Investigate how varying binder proportions of fly ash, ground granulated blast-furnace slag, and coral powder impact the fresh-state stability, mechanical properties, and microstructure of underwater engineered cementitious composites.
Prepared engineered cementitious composites with artificial seawater, coral sand, polyethylene fibers, non-ionic polyacrylamide, and varying ratios of fly ash, ground granulated blast-furnace slag, and coral powder.
Assessed fresh-state anti-washout stability, mechanical performance, multiple cracking behavior, and microstructural development under quiescent immersion and seawater curing conditions.
Fly ash-dominated mixtures achieved optimal fresh-state stability, demonstrating a 12-h apparent mass gain of 1.59% and the lowest final turbidity of 23.1 NTU.
Ground granulated blast-furnace slag-dominated mixtures yielded the highest mechanical ductility, reaching a compressive strength of 63.92 MPa, an ultimate tensile strength of 8.84 MPa, a tensile strain capacity of 9.76%, and 62 cracks with an average spacing of 1.29 mm.
High-volume coral powder substitution diminished fresh stability and tensile capacity, caused crack localization, and produced a coarser pore network with lower chemically bound water.
