DESCRIPTION: BVS PRO-SET 55 is an accelerating admixture for use in concrete and Portland Cement. BVS PRO-SET 55 is a ready to use liquid, added directly to the gauging water to allow for cold weather placement of concrete, Portland Cement, mortar and pre-cast members. It decreases critical cold weather setting time, loading to early high and ultimate increased strength and improved wear resistance properties. In addition, it reduces bleeding and segregation, and improves workability. BVS PRO-SET 55 contains no added chloride ions ensuring that the product does not contribute to the corrosion of reinforcing steel.

• Reduces set time on cold weathering applications
• Reduces water mix requirements
• Increases the high early and ultimate strength of concrete
• Improves workability
• Significant improvement in early stiffening and setting characteristics
• Assists in cold weather concrete scheduling
• Reduces efflorescence
• Does not contribute to the corrosion of reinforcing steel

MASONRY: BVS PRO-SET 55 reduces water requirements to achieve desired slump by as much as 15%. BVS PRO-SET 55 will enhance the effect of air Entraining agents. Add BVS PRO-SET 55 directly to the gauging water, NEVER TO THE DRY CEMENT.

CONCRETE: Add BVS PRO-SET 55 with water and proper agitation to ready mix concrete, do not dispense onto dry cement. When air temperatures are below 50°F (10°C), follow "Recommended Practice For Cold Weather Concrete" of the American Concrete Institute. BVS PRO-SET 55 reduces water requirements to achieve desired slump by as much as 15%. Air entrained concrete mixes containing BVS PRO-SET 55 display improved efficiency. When using air entrained cement, a patch test is required to determine level of air entrainment required.

* Dosage of BVS PRO-SET 55 per cubic yard of concrete is based upon a standard mix of 564 pounds of cement per cubic yard of concrete. Standard dosage is 16 ounces of BVS PRO-SET 55 per hundred weight (CWT) of cement. This dosage can be adjusted to as high as 32 ounces per CWT of cement for low temperatures.

When temperatures are below 25°F for long durations where cement is being placed, supplemental heat is required as per the recommendations of the American Concrete Institute.

When working with limed mortars in equal proportions to the cement, double the amount of BVS PRO-SET 55 required.

Check BVS PRO-SET 55 on a small amount of specialty mortars before use.

When temperatures are below 25°F for long durations where cement is being placed, supplemental heat is required as per the recommendations of the American Concrete Institute.

When using on cement mixed on the job site from bags, calculate the ration based on anticipated yield of mixed in cubic yards. For example, if mixing 1/2 cubic yard of cement above 25°F, .75 gallons of BVS PRO-SET 55 should be added to the gauging water. The gauging water should be reduced 10-15% to achieve desired slump.

When using BVS PRO-SET 55, exposed metal should first be coated with BVS VISTA-CLEAR VOC to prevent corrosion. (Temperature limitations apply to the application of BVS VISTA-CLEAR VOC, check directions before use)

PACKAGING: BVS PRO-SET 55 is available is 55 gallon drums and 5 gallon pails.

SHELF LIFE: BVS PRO-SET 55 if properly stored in its sealed container, one year. Rotate your stock.
