SECTION II - TEST PROCEDURES: The client provided a galvanized steel form having a clear acrylic plastic bottom. A wooden frame was built to enclose the steel / plastic form. The joints between the ClearCast form and the lumber were sealed with silicone caulk. Form oil was applied to the sides of the lumber to allow for stripping the concrete. The form was filled with concrete having a mix design typical of an ODOT mix for bridge deck concrete. The concrete was vibrated to consolidate the concrete. The concrete was allowed to cure for 5 days in a moist environment. After the 5 day cure time, two sides of the wooden outer frame were removed to expose the form and concrete. The unit was then placed inside the CSZ chamber for temperature cycling. A description of the test procedures utilized in conducting the Temperature Cycling of one (1) Clear Cast Form is as follows:

The sample was exposed to the following 8 hour cycles for forty-two (42) complete cycles: Ramp up from 77 ºF to 130 ºF in 0.5 hours Hold at 130 ºF for 3 hours Ramp down from 130 ºF to -30 ºF in 1.0 hour Hold at - 30 ºF for 3 hours Ramp up from - 30 ºF to 77 ºF in 0.5 hours Repeat for 42 complete cycles At the conclusion of 42 cycles the test unit was removed and returned to the client.

SECTION III - RESULTS OF TESTS: Cycle Testing began March 20, 2017 at 10:30 am and concluded April 3, 2017 at 10:30 am as described in Section II. The observations obtained during the Temperature Cycling on one (1) ClearCast Form are as follows: The test unit had no visible evidence of damage. There were no cracks in the plastic and no signs of crazing or fogging resulting from the temperature cycling. After removal of the concrete, a slight haze was observed over about 2% of the surface of the plastic when viewed at an angle. This area remained transparent and did not impede viewing the concrete surface. The sample was returned to the client upon completion of the test.
