BVS RAPID-REPAIR HIGH-STRENGTH PATCHING MORTAR |
DESCRIPTION: BVS RAPID-REPAIR is a cement based, rapid setting, high strength road patching mortar which will allow traffic to resume within two hours.
USES AND APPLICATIONS:
ADVANTAGES:
PACKAGING: BVS RAPID-REPAIR is packaged in a 50 lb. multi-ply bag.
YIELD: BVS RAPID-REPAIR will yield approximately 0.4 cu. ft. per 50 lb. bag.
STORAGE CONDITIONS: Store BVS RAPID-REPAIR at or above 45ºF (7ºC) in a dry area. Avoid excessive heat or humidity. Shelf life is one year in the original, unopened container.
POT LIFE: BVS RAPID-REPAIR has a working time of 10 minutes at 70ºF (21ºC). Cold water 40ºF (4ºC) will retard the set time and hot water 90ºF (32ºC) will accelerate the set time.
PRIMING: No priming is required with BVS RAPID-REPAIR.
COLOR: BVS RAPID-REPAIR is available in gray only.
SURFACE PREPARATION: Cut a vertical edge of at least 1/2 inch around the repair area with a masonry chop saw. Remove all spalled and unsound concrete from the repair area. Make sure that all loose, oily or greasy concrete is removed from the patch area. Thoroughly dampen the area with clean water, leaving no puddles. If reinforcing steel is exposed, follow the ICRA Technical Guidelines # 03730-03734. If the reinforcing steel is worn beyond repair, follow the ACI standards for the removal and installation of reinforcing steel.
MIXING: BVS RAPID-REPAIR may be mixed by manual or mechanical means. Manual mixing; use various size buckets and a margin trowel. Mechanical mixing; mix in a 5 gallon pail using a heavy-duty, slow speed drill (400-600 rpm) with a mixing paddle. Pour 3.5 quarts of water into an appropriate mixing container and then, while mixing, add the entire bag of BVS RAPID-REPAIR. Mix until a uniform, no slump consistency is obtained. Do not over mix! 2 minutes is all that is required. Only mix that which can be placed in 15 minutes. For applications greater than 2 inches in depth, 1/4 inch to 3/8 inch coarse aggregate may be added to BVS RAPID-REPAIR. Add 37 lbs. of clean and damp (SSD) aggregate to the BVS RAPID-REPAIR and mix for 1 minute. NOTE: BVS POLY-BINDER may be used as the mixing liquid if enhanced properties are required.
APPLICATION: BVS RAPID-REPAIR should be placed immediately after mixing. Dampen (SSD) the repair area and have no standing puddles. With a trowel work the BVS RAPID-REPAIR into the bottom and sides of the repair area to enhance the bond. Continue to fill the patch area and bring the material to a level just above the grade. Now screed the patch area and level to the existing concrete. After the initial set, the BVS RAPID-REPAIR may be troweled or broom finished.
CURING: BVS RAPID-REPAIR may be opened to traffic in 2 hours providing that temperatures have remained at or above 70ºF (21ºC). Lower temperatures will extend the time required before the repair area may be opened to traffic.
