How to Use clast in a Sentence

clast

noun

• Hot mixing left these lime clasts embedded throughout the mortar.
  — Encyclopedia Britannica, 9 July 2026
• These cracks were filled by the lime clasts that reacted with salt or rainwater to recrystallize.
  — Encyclopedia Britannica, 9 July 2026
• When cracks form in Roman concrete, water seeps in and dissolves calcium from the lime clasts.
  — Encyclopedia Britannica, 9 July 2026
• The new research focused on clasts, fragments broken off from the mountain during the landslide.
  — Mrigakshi Dixit, Interesting Engineering, 20 Aug. 2025
• Roman concrete, for instance, could repair its own cracks thanks to lime clasts, which react with water to seal fractures.
  — Georgina Jedikovska, Interesting Engineering, 11 Feb. 2026
• The ultimate test of lime clasts’ success is exposure to the elements.
  — Encyclopedia Britannica, 9 July 2026
• Because limestone is rich in calcium, these clasts act as calcium reservoirs.
  — Encyclopedia Britannica, 9 July 2026
• Water was then added, creating a chemical reaction that produced heat and trapped the lime clasts in the concrete.
  — Taylor Nicioli, CNN Money, 19 Dec. 2025
• Lime clasts are tiny white chunks of limestone that were previously mistaken for evidence of sloppy mixing.
  — Encyclopedia Britannica, 9 July 2026
• The method created white chunks called lime clasts, and when water seeped in, those clasts would dissolve and reform into calcium carbonate, allowing the concrete to heal and seal the damage.
  — Andrea Margolis, FOXNews.com, 23 Dec. 2025
• Although pozzolanic material does strengthen the structure, researchers now believe that the lime clasts unlock the concrete’s self-healing power.
  — Encyclopedia Britannica, 9 July 2026
• Recent research suggests the material contains lime clasts that can react with water and help seal cracks over time, effectively giving the concrete self-healing properties.
  — Kaif Shaikh, Interesting Engineering, 30 May 2026
• The researchers were cemented in history for their use of high-resolution multiscale imaging and chemical mapping techniques to identify the lime clasts.
  — Encyclopedia Britannica, 9 July 2026
• When cracks form, water dissolves calcium-rich material from the clasts, which then recrystallizes as calcium carbonate, sealing the fracture.
  — Sam MacDonald, Scientific American, 11 July 2026
• In 2023, researchers at MIT and elsewhere proposed that the bright white chunks scattered throughout Roman concrete—known as lime clasts and long dismissed as evidence of incomplete mixing—could help explain the material’s self-healing properties.
  — Sam MacDonald, Scientific American, 11 July 2026
• Using modern micro-CT scanning, which employed medical-level scans on the previously untouched core samples from the Light Mantle, Magnarini and her colleagues investigated clasts, which are rocky fragments that broke off from the slope of South Massif.
