diameter and 4 inches high. When tested at 28 days
the compressive strength shall not be less than 1800
pounds bed square inch.
C. Grout specimens shall be cast in block cell using
masonry units taken from the site. Grout shall be
poured into the sample units and puddled, as nearly as
possible, in the same manner as that being poured into
the wall. Specimens shall remain in the block for 3
days. Line block with a thin paper towel to permit
removal of the specimen without damage. This specimen
shall be tested for compression at 28 days and shall
develop a minimum ultimate compressive strength of
2000 pounds per square inch.
