Product Description:

High-range Water Reducing Admixture Naphtalene Sulfonate FormaldehydeHigh-range Water Reducing Admixture Naphtalene Sulfonate Formaldehyde

DESCRIPTION
SBTJM
-A high-range water reducing admixture is a powder of beta-sulphonate formaldehyde condensate.  The Na2SO4 content is within 18-20%. It has the performances of non-air-entraining, high-range water  reducing and strengthening. It is in particular suitable to produce concrete with the requirement of high  water reduction, high-early strength. SBTJM-A is formulated to comply with the following  specification for concrete admixture: ASTMC494, Type F; GB8076-1997.

FEATURES:

High water reduction
Tested according to GB8076-1997, the water reduction is around 16% at the addition rate of 0.5%  by weight of cementitious materials.


Superplasticizing
The addition of SBTJM
-A 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.


High strengths
At the addition rate of 0.5%, it can improve the compressive strength of concrete at the ages of 3d, 7d

and 28d by 65%~75%, 45-55%, 25-35% 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-A and control concrete is normally within one hour.


Wide range of application temperature
The feasible application temperature ranges from -5℃ to +45℃.


Excellent durability
The addition of SBTJM
-A 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.

USAGE:

Addition rate
The normal range of SBTJM
-A addition rate is 0.4-0.6% by weight of cementitious material  and can be increased to 0.8% for early-strength concrete.


Blending
SBTJM
-A 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.


PACKAGING:
SBTJM
-A 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.
