Dispersant/Water Reducer

ConTec SD-215C Super Plasticizer features cutting-edge polycarboxylate technology. It’s highly active formulation is for wet-cast production water-reduction. SD-215C improves cement hydration and provides higher compressive strength in wet-cast concrete products. It features very fast slump increase for high speed in plant wet-cast production.

Features & Benefits

  • Improves cement particle dispersion and hydration
  • Reduces water & increases slump
  • Increases compressive and flexural strength
  • Proper use can potentially reduce cement and pigment usage
  • Improves placement and consolidation


Use ConTec SD-215C  in plant wet-cast production where improved slump increase is desired. Use of ConTec SD-215C admix breaks up agglomerations to increase the cement surface available for hydration. ConTec SD-215C also increases slump and stabilizes air-entrainment.

ConTec SD-215C



ConTec SD-215C is available in bulk quantities or packaged in 55 gallon (208 L) drums weighing 500 lb (227 kg) and 255 gallon (919 L) totes weighing 2,320 lb (1,052 kg).


ConTec SD-215C should be stored at temperatures above 35 F (2 C). Care should be taken to prevent this product from freezing. Should SD-215C freeze, warm till completely liquid then use mechanical agitation to reconstitute.


The recommended dosage rate is 0.2% by weight of cement. In dry-cast concrete products SD-205 will increase the demand for water by 5 to 10% above normal addition rates. SD-205 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. Never mix SD-205 with other admixtures before application.
