Description

U-ChemPlast HRWR-LR is a ready-to use liquid admixture comprising of synthetic polymers specially designed to impart rheoplastic qualities to concrete. It is a high range water-reducing admixture with retarding effect. It contains no chloride.

A rheoplastic concrete is a fluid concrete with a slump value of at least 200 mm, easily flowing but at the same time free from segregation, and having the same water/cement ratio as that of a no-slump concrete of 25 mm without additive.

RECOMMENDED FOR 

  • mass concrete
  • ready-mixed concrete
  • long distance transportation of concrete
  • pumped concrete
  • hot weather concreting
  • use with all cements and air-entraining admixtures approved under ASTM, AASHTO, CRD and BSI specifications

It has been used for:

  • foundation of high rise buildings
  • transporting of concrete lasting more than one hour
  • casting structures where concrete is pumped over a distance of more than 200 meters or to a considerable height.
  • reinforced concrete and pre-stressed concrete structures in regions where temperatures normally exceed 40ºC and relative humidity is low
