Finish TradesCâu 234 / 700
Before installing resilient flooring over a concrete slab, moisture is tested. In the anhydrous calcium chloride test (MVER), results are reported in:
a.Percent slope of the slab
b.Degrees of surface temperature
c.Pounds per square inch of compressive strength
d.Pounds of moisture emitted per 1,000 square feet in 24 hours
Giải thích
The calcium chloride test measures moisture vapor emission rate (MVER) in pounds per 1,000 square feet per 24 hours, which is compared to the flooring manufacturer's limit. Slope, temperature, and compressive strength are unrelated to that moisture measurement.
