Description
NUGATARD is a ready to use liquid based on mixture of polymers allows the production of retarded concrete with increased ultimate strength. It produces a more uniformly cohesive quality concrete to meet the specifications and needs of users (Engineers, Contractors, Consultants and Architecs).
NUGATARD needs to the requirements B.S. 5075 part 3, 1982 and ASTM type D.
When is used NUGATARD will provide the following benefits:
– Improved workability/reduce w/c (water/cement) ratio
– Flexible degree of retardation
– High resistance to segregation/reduces bleeding
– Improve surface finish
– Reduce shrinkage cracking potential
– Higher initial and ultimate compressive strengths
– Higher durability concrete
Application – NUGATARD is used for the following applications:
– Ready mix concrete
– Precast concrete
– Pumped concrete
– Light weight concrete
– Wet shotcrete
– Semi-dry concrete
Dosage of NUGATARD is 0.1 – 0.5 Liter/100 kg cement. It is advisable to do initial site trials to determine the optimum dosage.
NUGATARD should be added to the mixing water. Where concrete is being mixed by ready mixed trucks, NUGAPLASTIZER can be added at the batching plant but the trucks must rotate their drums until a uniform mix is achieved. To produce flowing concrete a well proportioned pump mix should be used. NUGATARD is compatible with all types of Portland Cements and NUGAPLASTIZER.
Typical Physical Properties:
Form: Liquid
Color: Clear
Density (g/mL): 1.18 – 1.23

Environmental – NUGATARD is a non-toxic or not hazardous materials. Please refer to the MSDS.
Packaging – NUGATARD is optionally packaged in 200 liter plastic drum, 1000 liter IBC or Tank containers.
Handling and Storage – NUGATARD is considered low irritating to eye and skin, however the usual precautions for handling chemicals should be observed. Avoid contact with eye and skin by wearing goggles and gloves. For skin contact washes with water and soap, while eye contact flush with clean water for 15 minutes. Ingestion: seek urgent medical care. Keep container tightly closed and headspace of bulk storage tanks must be kept saturated with water vapour. This product must not be exposed to high temperature and must be protected from sunlight and frostNUGATARD has a shelf life of 12 months at 10-35oC, provided due attention is paid to the hygiene of tanks and storage facilities.
