What does this research mean for the field?

In ground granulated blast furnace slag-based alkali-activated concrete, a 15M sodium hydroxide concentration combined with an alkaline solution-to-binder ratio of 0.25 optimizes mechanical performance and dimensional stability, achieving a peak 28-day compressive strength of 64 MPa. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

Implication

Experimental study demonstrates enhanced stiffness and reduced shrinkage in alkali-activated slag concrete, highlighting an effective low-carbon alternative to conventional cement.

Key Points

To evaluate the mechanical, elastic, and deformation behaviors of ground granulated blast furnace slag concrete activated with sodium hydroxide and sodium silicate under ambient curing.
Tested ground granulated blast furnace slag concrete across two sodium hydroxide concentrations (3M and 15M) and two alkaline solution-to-binder ratios (0.25 and 0.30) under ambient curing conditions.
Evaluated the effects of carboxymethyl cellulose and calcium carbide replacement levels (2.5%, 5%, 7.5%, and 10%) on matrix densification and rheological performance.
Measured compressive strength, static modulus of elasticity, Poisson's ratio, dimensional creep, and drying shrinkage.
Mixtures prepared with 15M sodium hydroxide and a 0.25 alkaline solution-to-binder ratio achieved a peak 28-day compressive strength of 64 MPa.
The optimal mix design achieved a static modulus of elasticity of 47,322 MPa alongside a minimized drying shrinkage of 0.302%.
