ConTec NC-537P is a non-corroding, chloride free accelerator/plasticizer blend. As a result, it does not corrode metal block and paver pallets or machine parts. Use it to promote early strength development and ease of manufacturing in concrete masonry unit (CMU) mix designs. By increasing hydration speed, NC-537P helps offset the effects of cold weather. Use it year-round to shorten time between CMU manufacture and splitting or tumbling.
ConTec NC-537P is compatible in all CMU mixes. It may be added to the mix on the sand or in the water.
