9) How many blocks are needed to complete the 4 - foot - high foundation wall in Figure 2 if it is constructed of 7 5/8 - inch - high by 7 5/8 - inch - wide by 15 5/8 - inch - long concrete blocks with a 3/8 inch mortar joint?

10) Determine the number of 2 1/2 - inch - high by 3 1/2 - inch - wide by 11 1/2 - inch - long bricks that are required to face a wall 50 feet long by 6 feet high. Allow for a 1/2 inch mortar joint.

11) Determine the number of corrugated masonry ties that are required to tie the brick facing to the wood framing for a wall 50 feet long by 6 feet high wall. The spacing between the ties is to be 12 inches measured vertically and 24 inches measured horizontally. Ties are to be located within 6 inches of the ends. The brick facing sits on a concrete foundation wall.

12) Determine the quantity of mortar needed for a 50 - foot - long by 6 - foot - high brick - faced wall if 9.2 cubic feet of mortar is required per 100 square feet of brick.

13) How many 2 1/2 - inch - high by 3 1/2 - inch - wide by 7 1/2 - inch - long bricks are required to face the wall in Figure 3? Allow for a 1/2 inch mortar joint.

14) Determine the number of corrugated masonry ties that are required to complete the wall in Figure 3. The spacing between the ties is to be 12 inches measured vertically and 30 inches measured horizontally. Ties are to be located within 6 inches of the ends. The brick facing sits on a concrete foundation wall.

15) Determine the quantity of mortar needed for the wall in Figure 3 if 10.3 cubic feet of mortar is required per 100 square feet of brick.

16) Excel Quick Tip 6 - 1: Block Wall

Determine the materials needed to construct 82 feet of 6 - foot - high wall. The wall is constructed of 7 5/8 - inch - high by 5 5/8 - inch - wide by 15 5/8 - inch - long blocks with a 3/8 - inch mortar joint. The bond beams are spaced four feet on center and contains two #4 rebar. The wall is vertically reinforced by a #5 rebar at 24 inches on center. The rebar is to be lapped 30 bar diameters. The horizontal bars are to be ordered in 20 foot lengths. Historical data show that 6 cubic feet of mortar and 19 cubic feet of grout are needed for 100 square feet of wall.

17) Excel Quick Tip 6 - 2: Brick Wall

Determine the number of bricks, corrugated masonry ties, and mortar needed to face a wall 80 feet long by 8 feet high. The brick is 2 - 1/2 inches high by 3 - 1/2 inches wide by 7 - 1/2 inches long. Allow for a half inch mortar joint. The spacing between the ties is to be 24 inches measured vertically and 24 inches measured horizontally. Historically 13.1 cubic feet of mortar is required per 100 square feet of brick.
