Dispersant/Water Reducer
Innovative Concrete Technology’s ConTec SD-250HS is a high-performance polycarboxylate super dispersant engineered specifically for architectural concrete, hardscape products, and other manufactured concrete applications. Utilizing advanced dispersion technology, SD-250HS improves cement hydration, enhances pigment performance, and helps producers achieve stronger, denser, and more visually appealing concrete products.
Features & Benefits
- Improves cement particle dispersion and hydration
- Aids pigment particle dispersion improving color development
- Increases compressive and flexural strengths
- Helps cost by reducing cement usage
- Creates sharper, crisp angles improving overall appearance
- Increases density, strength development
- Produces a low to moderate swipe
Applications
ConTec SD-250HS is ideal for a wide range of drycast concrete products, including:
- Standard and architectural concrete block
- Pavers and hardscape units
- Retaining wall systems
- pecialty drycast and masonry product
Why Choose ConTec SD-250HS?
Concrete performance starts at the particle level. Cement particles naturally form clumps, known as agglomerations, which limit water access and reduce hydration efficiency. SD-250HS breaks apart these agglomerations, increasing available surface area and allowing more complete hydration throughout the mix. Whether you’re manufacturing pavers, retaining wall systems, slabs, or other architectural concrete products, SD-250HS helps deliver the combination of strength, color vibrancy, density, and refined surface aesthetics that customers notice immediately. The result is concrete that not only performs better, but also looks better.

TECHNICAL INFORMATION
ConTec SD-250HS is available in bulk quantities or packaged in 55 gallon (208 L) drums weighing 500 lbs (227 kg) and 243 gallon (919 L) totes weighing 2205 lbs (1000 kg).
ConTec SD-250HS should be stored at temperatures above 35 F (2 C). Care should be taken to prevent this product from freezing. Should ConTec SD-250HS freeze, warm till completely liquid then use mechanical agitation to reconstitute.
The recommended dosage rate for ConTec SD-250HS is 1 to 4 fluid ounces per hundred weight of cement. In dry-cast concrete products SD-250HS will increase the demand for water by 5% to 10% above normal addition rates. Please consult an ICT representative for further recommendations to determine the proper dosage rate and order of addition for your particular process. Order of addition procedures can vary per facility. Never mix SD-250HS with other admixtures before application.
