Salty Mine Water Turns Coal Waste Into Stronger Underground Backfill
Chinese researchers show that highly saline concentrated mine water can replace tap water in coal-waste backfill, boosting early strength when ...
Slow-Release Alkalinity Turns Slag Cement Into a Stronger, Greener Binder
New research shows that the rate at which clinker-based activators release alkalinity, rather than the total amount supplied, controls crystal ...
Deep-Sea Pressure Supercharges the Sulfate Attack That Eats Away at Underwater Concrete
New experiments and simulations show that even moderate hydrostatic pressure dramatically accelerates sulfate ingress and ettringite formation in cement paste, ...
Hempcrete Gets a Strength Boost: Sulphate Additive Makes Carbon-Negative Building Material Tougher
South African researchers show that adding three percent potassium sulphate to hempcrete nearly doubles its compressive strength and reduces shrinkage ...
Natural Clay Nanotubes Shield Concrete From Sulfate Attack at a Fraction of the Cost
New research shows that naturally occurring halloysite nanotubes, dispersed with a common superplasticizer, dramatically improve cement mortar's resistance to sulfate ...
Tiny Particles, Big Defense: Nanoparticles Shield Concrete From Sulfate Attack
A 180-day immersion study shows nano-silica outperforms nano-calcium carbonate in shielding cement mortar from sulfate attack, with optimal dosages of ...
Scientists Track the Mineral That Crumbles Concrete From the Inside Out
Researchers have mapped the complete oxidation sequence of pyrrhotite in concrete aggregates, linking laboratory-accelerated samples to severely damaged field concrete ...
Tiny Doses of Cement Could Turn Wood Ash Into a Viable Green Building Material
French researchers found that adding just 5 to 20 percent ordinary Portland cement to binders made almost entirely of wood ...
