BMI 3000 Coarse Grout Mix
Description
BMI 3000 is a coarse grout mix that consists of sand, gravel and Portland Cement. BMI 3000 coarse grout is used to fill concrete block or to build small concrete walks, floors, footings and for post setting at home. BMI 3000 is also suitable for minor non-structural concrete repairs.
Mixing
BMI 3000 coarse grout contains all the ingredients in dry form, only water needs to be added. Mix one bag of BMI 3000 with 1.5 gallons of water for grouting of block or with 1 gallon for concrete work. Try to avoid a soupy mix, as this reduces strength.
Coverage
BMI 3000 coarse yields approximately 0.75 cu. ft. of concrete. One ton of BMI 3000 yields 18 cu. ft. of concrete.
Application
For grouting of block, pour the concrete mix into block and rod with rebar to ensure that there are no unfilled voids inside the block. For concrete work, make a frame and put concrete inside the frame and compact it firmly. Use a straight edge to remove excess concrete. For a rough finish use a wooden float or brush, for smooth finishes use a steel trowel. Do not over trowel since this can lead to cracking. Keep concrete damp for a minimum of two (2) days. Do not spray with water before concrete has set.

* These are laboratory tests according to ASTM C-476 and are simulating the strength in the block when tested in prisms (not cylinders). Field tests from cylinders will be lower due to the fact that no water absorption takes place in the cylinder.
