1.3.15.2
Measurement
Measurement of drilling and plugging cracks will be made on the basis of
the actual volume of [portland cement grout][polymer-modified
mortar]placed, and accepted, within the limits of work as indicated on the
contract drawings.
1.3.15.3
Unit of Measure
Unit of measure: cubic meter foot.
1.3.16
Gravity Crack Filling
1.3.16.1
Payment
Payment for gravity filling of cracks will be made at the contract unit
price per square meter yard. This payments shall constitute full
compensation for performing the work and shall include the cost of all
labor, equipment and tools, materials and supplies required to complete the
gravity filling work under this contract, including surface preparation.
1.3.16.2
Measurement
Measurement of gravity crack filling will be made on the basis of the
actual area of concrete surface treated, within the limits of work, as
indicated on the contract drawings.
1.3.16.3
Unit of Measure
Unit of measure: square meter yard.

Repair Materials
**************************************************************************
NOTE: If higher earlier strength is needed for
repairs, revise this paragraph to provide
appropriate criteria. The mixture design should
maximize aggregate size and minimize the
water-cementitious material ratio to reduce
shrinkage. Material properties should be
coordinated with EM 1110-2-2002 Evaluation and
Repair of Concrete Structures. Where other guide
specifications are included in the project
specification, ensure that appropriate parameters
are inserted in the applicable specification.
Consideration should be given to including and
alternative age other than 28 days such as 90 days
when pozzolan is used to provide more cost effective
use of materials. If flowability of the grout is
important, use ASTM C 1017/C 1017M for admixture and
specify where it is to be used; otherwise use ASTM C
494.
