SBTJM-V concrete frost-resistance admixture

DESCRIPTION
SBTJM-V concrete frost-resistance admixture is a new frost resistance material which has the advantages of water reducing effect, strengthening effect, air-entraining and freezing point decreasing effects. It is particularly adaptable to the concrete project at low temperature. The lowest construction temperature

can be to -15℃ while SBTJM-V is used.

TECHNICAL PROPERTIES
● Excellent frost resistance
Under -15℃ the strength R-7+28 of concrete with JM-V is 104%, R-7+56 is 112% compared to  that of the reference concrete.

● High water reducing and strengthening effect
SBTJM-V has obvious water reducing effect (according to the relative specifications in GB8076-1997). The water reduction of concrete with JM-V is above 15%.

● Highly strengthening effect
The 1d strength of concrete in standard curing is 300% compared to that of the reference concrete, which

can effectively short the construct-period and improve the form turnover. The compressive strength is 110% at the age of 28days compared to that of the reference concrete.

● Excellent durability
The addition of SBTJM-V can effectively improve the pore structure of the concrete and increases the frost-resistance, carbonation-resistance and corrosion-resistance. The product has not chlorine and nitrite  etc, and no corrosive substance to the steel bar.

USAGE

● The dosage range of SBTJM-V is 2-5%, recommended dosage is shown in the table below

The lowest construction temperature (℃)	-5	-10	-15
Addtion rate	2-3%	3-4%	4-5%

● Blending: the product should be blended with cement, sand and stone, and should not be dissolved beforehand.

Ensure accurate measurement and prolong the blending time a little to ensure well distribution.

● Curing: after pouring, it must be covered immediately for insulated curing.

● Shelf life: it should be stored in dry place. Its quality guarantee is normally within two years.

● PACKAGING

SBTJM-V is packaged in anti-wetting double-layer plastic bags and has net weight  of 40kg per bag.  It’s convenient for transportation.
