Geopolymer-based concrete composition
Patent published on the 2025-06-26 in WO under Ref WO2025137733 by PLANTAER INC [US] (Abdallah Robert Joseph [us], Ruiz Manuel Jesus Benitez [us])
Abstract: Embodiments provide a novel concrete composition and method for forming a geopolymer-based building material. The composition comprises a geopolymer binder, water-retentive aggregates with long-term water retention properties and biological surface growth facilitation, where at least one aggregate is cellulose pre-treated with a saturating coating solution. The composition also includes rigid, porous aeration aggregates and strength aggregates. The method involves mixing these components to form[...]
Our summary: Novel geopolymer-based concrete composition with water-retentive aggregates, cellulose pre-treated aggregates, and aeration aggregates. Method involves mixing components to form pourable material, then curing under controlled conditions. Construction material includes aluminosilicate precursor, biopolymer-coated aggregates, and porosity agent for enhanced sustainability and durability.

Interesting read, but arent we underestimating the environmental impact of these surface coatings? Lets discuss green alternatives, folks!
Interesting read, but arent we overlooking the environmental impact of these surface coatings? What about sustainability?
Interesting read, but do these new patents imply the redundancy of traditional surface coating techniques?
