Donplast® RGP
Recycled Glass Pozzolan
Donplast RGP is a fine, white colored, amorphous, glass powder made from 100% recycled glass with excellent pozzolanic properties and a similar water demand to ordinary Portland cement.
Unlike silica fume, coal fly ash, ground granulated blast furnace slag, and other by-products, Donplast RGP is free of iron, manganese, and other undesirable color-inducing impurities, making it ideally suited for all applications using white cement and in decorative and pigmented concrete.
Donplast RGP Pozzolans will react with calcium hydroxide produced during the hydration of Portland cement to form additional cementitious compounds such has calcium silicate and alumina-silicate hydrates.
- Excellent late strength gain and high cement substitution rates.
- Lower water demand.
- Significant reduction in Greenhouse Warming Potential (GWP).
- Improved concrete durability with lower permeability and enhanced chloride resistance.
- Preferred lighter color, sometimes approaching white.
- Effective mitigation of Alkali.
- Reduces bleeding and segregation by improving the concrete workability and cohesiveness.
- Greatly improved freeze/thaw and scaling resistance.
- Improves concrete pumpability.
- Ready Mix Concrete (architectural, design and white cement).
- Pre-cast.
- High performance concrete (HPC).
- Ultra high-performance concrete (UHPC).
- Piles and structural concrete elements.
- Decorative concrete requiring white siliceous materials.
- The low iron content makes it particularly well suited for applications using white cement, such as mortars, stuccos, terrazzo, artificial stone, and cast-in-place or precast concrete products.
Available in 50 lb (22.7 kg) bags, and bulk supply. Other packaging options are available on request.
Donplast RGP has a shelf life of 12 months from date of manufacture if stored in dry area at temperatures over 36oF (2°C).
Donplast RGP complies with ASTM C1866/CSA A3000-21.
