with a parge coat of mortar proportioned by mass of one part portland
cement, two parts sand, and sufficient water to make the mixture placeable.
The parge coat shall have a smooth, dense finish. The exposed surface of
other types of nonshrink grout shall have a smooth, dense finish.
3.6.2.3
Curing
Grout and parge coats shall be cured in conformance with paragraph CURING
AND PROTECTION.
3.7
TESTS AND INSPECTIONS
Tests and inspections shall conform to the following requirements.
3.7.1
General
**************************************************************************
NOTE: The title of the certification provided by
ACI that concrete inspectors/technicians have to
have to perform concrete testing was changed from
"Concrete Transportation Construction Inspector" to
"Concrete Construction Inspector" in 2004. Since
the certification is good for 5 years, both titles
will be kept in the specifications through 2006;
pick the correct bracketed statement for projects
prior to 2004.
**************************************************************************
The Contractor shall perform the inspections and tests described below,
and, based upon the results of these inspections and tests, he shall take
the action required and submit reports as required. When, in the opinion
of the Contracting Officer, the concreting operation is out of control,
concrete placement shall cease. The laboratory performing the tests shall
be on site and shall conform with ASTM C 1077. The individuals who sample
and test concrete or the constituents of concrete as required in this
specification shall have demonstrated a knowledge and ability to perform
the necessary test procedures equivalent to the ACI minimum guidelines for
certification of Concrete Field Testing Technicians, Grade I. The
individuals who perform the inspection of concrete construction shall have
demonstrated a knowledge and ability equivalent to the ACI minimum
guidelines for certification of [Concrete Transportation Construction
Inspector (CTCI)] [Concrete Construction Inspector (CCI)]. The Government
will inspect the laboratory, equipment, and test procedures prior to start
of concreting operations and at least once per year thereafter for
conformance with ASTM C 1077.
3.7.2
Testing and Inspection Requirements
3.7.2.1
Fine Aggregate
a. Grading - At least once during each shift when the concrete plant
is operating, there shall be one sieve analysis and fineness modulus
determination in accordance with ASTM C 136 and COE CRD-C 104 for the
fine aggregate or for each size range of fine aggregate if it is
batched in more than one size or classification. The location at which
samples are taken may be selected by the Contractor as the most
advantageous for control. However, the Contractor is responsible for
delivering fine aggregate to the mixer within specification limits.
