Determines effects of variations in concrete of the  concrete to the freeze-thaw cycles in water in the laboratory as specified in the procedure. Correlation between concrete strength and durability tests provides means of establishing field control.
Unit tests up to 18 specimens, 3x4x16" (76x102x406mm) maximum size in stainless steel containers simultaneously. 3/4 HP (0.6KW) refrigeration unit reduces temperatures to 0°F (-17.8°C) and uses electronic resistance heaters to thaw.
Produces up to 9 freeze-thaw cycles in a 24-hour period. Cycle length depends on time required to reduce temperature at center of control prism from 40 to 9°F (4.4 to -17.8°C) and back to 140°F (4.4°C). Electric-drive, 7-day operation, recording thermometer keeps continuous record of temperature at center of control specimen.
Fully automatic controls, including testing sequence operation. Trays may removed whenever desired. Stainless steel 84x34x11" (213x86x30cm) cabinet on steel frame. Freeze-thaw compartment I.D. is 6x26x74" (15x66x188cm). Requires minimum 30 amp circuit. Order H-3195 freeze-thaw molds separately. Meets ASTM C666.
