Implication

Investigates strength enhancement in a waste-derived construction material, suggesting a pathway for sustainable engineering.

Key Points

  • The research aims to develop a novel controlled low-strength material (CLSM) using industrial by-products to tackle waste disposal and low-carbon construction challenges.
  • Utilized calcium carbide residue (CCR) as an alkali activator for ground granulated blast furnace slag (GGBS) and fly ash (FA).
  • Conducted unconfined compressive strength (UCS) tests and microstructural analyses using X-ray diffraction (XRD) and scanning electron microscopy with energy dispersive spectroscopy (SEM-EDS).
  • Varying binder content (10%, 15%, 20%, 25%) and sand-to-soil ratios (0:10, 1:9, 3:7, 4:6, 5:5) were employed during testing.
  • The 28-day UCS reached a peak of 5061.13 kPa with 25% GGBS-FA content and a 4:6 sand-to-soil ratio.
  • In the 25% GGBS-FA group, the 3-day UCS decreased from 2031.26 kPa at a 0:10 ratio to a minimum of 940.30 kPa at 3:7, then rebounded to 1525.30 kPa at 5:5.
  • Microstructural analyses showed that CCR provided a highly alkaline environment, enhancing the strength and density of the material.
