CONCRETE TESTING Clause Samples

CONCRETE TESTING. The Contractor will prepare test cylinders in sets of three for each 100 cubic yards in the mat pour, or day’s pour for subsequent concreting. Slump tests are to be made at the time the cylinders are cast. Care in preparation, storage, labeling, and subsequent transportation of the test cylinders is required.

CONCRETE TESTING. This item also includes all costs associated with concrete testing (slump, air, and cylinder samples complete with associated breaks) as per CAN/CSA A23.3 and CAN/CSA A23.2 latest edition for each unit. Note the following regarding concrete tests:

CONCRETE TESTING. Slump tests shall be made in accordance with CSA Standard Test Method A23.2- 5C-04, "Slump of Concrete". If the measured slump falls outside the limits in E20.3.2 of this Specification, a second test shall be made. In the event of a second failure, the Contract Administrator reserves the right to refuse the use of the batch of concrete represented.

CONCRETE TESTING. Geo-Hydro’s technicians will be present to sample and test structurally significant concrete. Typically, for each sampling event we will perform physical tests to determine the slump, air content, and temperature, and we will cast test cylinders for subsequent compressive strength testing. We will transport cylinders to our laboratory for moist-curing and compressive strength testing which will be performed at the required test interval. We will sample and test the masonry in accordance with the project specifications and applicable ASTM standards. The mortar and grout specimens will be transported to our laboratory for subsequent compressive strength testing. We will also observe the installation of reinforcing steel during masonry construction and perform observation of structural masonry grouting as required by the IBC.
