ConTec SD-220 features cutting-edge polycarboxylate technology. It’s highly active formulation improves both cement and color pigment efficiency in all types of architectural and hardscape concrete units. SD-220 improves cement hydration and provides higher compressive strength in manufactured concrete products.
Features & Benefits
Improves cement particle dispersion and hydration
Aids pigment particle dispersion improving color development
Increases compressive and flexural strength
Paper use can potentially reduce cement and pigment usage
Improves the compaction process enhancing finished density
ConTec SD-220 can be used in all types of architectural and hardscape concrete units where better pigment particle dispersion and cement hydration is desired. Contact your ICT representative to help you design a mix that will use SD-220 to reduce manufacturing cost.
ConTec SD-220 is available in bulk quantities or packaged in 55 gallon (208 L) drums weighing 500 lb (227 kg) and 243 gallon (919 L) totes weighing 2,205 lb (1,000 kg).
HANDLING & STORAGE
ConTec SD-220 should be stored at temperatures above 35 F (2 C). Care should be taken to prevent this product from freezing. Should SD-220 freeze, warm till completely liquid then use mechanical agitation to reconstitute.
The recommended dosage rate for SD-220 is 0.18% by weight of cement. In dry-cast concrete products SD-220 will increase the demand for water by 5% to 10% above normal addition rates. SD-220 is not a water reducer and should not be utilized as such. 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 very by facility.
