High-Range Water Reducing Admixture Naphtalene Superplasticizer
High-range water reducing admixture is a powder of beta-sulphonate formaldehyde condensate. The Na2SO4 content is less than 5%. It has the performances of non-air-entraining, high-range water reducing and strengthening effects. It is in particular suitable to produce concrete with the requirement of high water reduction, and low Na2SO4 content. It can also be used as the water-reducing gradient of composite concrete admixtures.It is formulated to comply with the following specification for concrete admixture: ASTMC494, Type F; GB8076-1997.

The addition of SBTJM-B effectively improves the fluidity of the concrete and reduces the bleeding and segregation tendency of concrete. Therefore it improves the workability
of the concrete and makes the concrete easy for pumping and compacting.
At the addition rate of 0.5%, it can improve the compressive strength of concrete at the ages of
3d, 7d and 28d by 70%~80%, 50-60%, 30-40% respectively.
Little change of set time
It has little influence on the initial and final setting time of the concrete. The set time difference
between concrete which SBTJM-B and control concrete is normally within one hour.
Wide range of application temperature
The feasible application temperature ranges from -5℃ to +45℃.
The addition of SBTJM-B can effectively improve the pore structure of the concrete and increase the durability such as impermeability, carbonation resistance and frost resistance.
Easy for use
It can be added directly into concrete or dissolved beforehand into liquid state. It matches the
requirement of different application condition or mixer type.
The normal range of SBTJM-B addition rate is 0.4-0.6% by weight of cementitious material.
SBTJM-B should be blended previously with cement. Do not add it directly into wet aggregate. It can be dissolved into water solution before used as liquid admixture.
SBTJM-B is packed in the waterproofing double-layer plastic bag and the net weight is 25 kg per bag. It will not degenerate within its shelf life. Pay attention not to stave the bag and keep waterproofing
during the storage and transportation. If the product is wetted into agglomeration, it can be crushed
into powder before use and has no influence on the performances.
