Overview

This study compares compressive and splitting tensile strengths of AASF mixtures with high- and low-calcium fly ash, indicating the impact of curing conditions.

Key Points

  • HCFA mixtures showed enhanced compressive strength, especially at lower water-to-slag cement ratios, emphasizing material benefits.
  • Lower slump flow and higher flow loss in HCFA mixtures suggest specific challenges in workability compared to LCFA mixtures.
  • This experiment evaluated multiple water-to-slag cement ratios to understand their effects on the mechanical performance of AASF systems.
  • Findings suggest optimal combinations of fly ash types and water-to-slag cement ratios may improve eco-efficient construction materials.
