Contec SD-220

DESCRIPTION

ConTec SD-220 is a dispersing aid featuring cutting-edge polycarboxylate technology. It’s highly effective formulation improves 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. Your ICT technical representative can help you design a mix that will used SD-220 to actually reduce manufacturing cost.

TECHNOLOGY

Cement particles stick together in clumps called agglomerations. This clumping prevents water from reaching all the cement. Use of ConTec SD-220 admix breaks up agglomerations to increase the cement surface area available for hydration. The increased surface area holds more water without slumping your mix.  Maximizing the water content of zero-slump mixtures will maximize your results with SD-220.

ConTec SR-550

DESCRIPTION

ConTec SR-550 is a ready-to-use liquid admixture used to retard setting times by controlling the hydration of cement in the manufacture of concrete products. SR-550 is compatible with a wide range of concrete admixtures , but should always be dispensed separately. SR-550 improves the properties of precast concrete when used in conjunction with air entrainment, such as AE-80 or AE-407.

APPLICATION

ConTec SR-550 may be used wherever the need to retard the initial and final set times of concrete is applicable. SR-550 meets ASTM C 494/c 494M standards for Type B retardation and Type D water reducing admixtures. SR-550 improves uniformity and predictability in high performance concrete.

PACKAGING

ConTec SR-550 is available in bulk quantities or packaged in 55 gallon (208 L) drums weighing 495 lbs (224 kg) and 265 gallon (1003 L) totes weighing 2385 lbs (1082 kg).
