Question #: 24
Topic #: 3
When installing refractory castables in hot weather conditions, which of the following is acceptable? (This may have more than one correct answer; please select all that apply.)
API TR 980 provides guidance for hot weather installation, recommending:
“Preventive measures include shading material and equipment, cooling of mix water and forms, and in some cases, air conditioning of ambient air. Spraying water on equipment may be used to reduce radiant heat.”
— API TR 980, Section 4.5.2
However, decreasing mixing time is not advised; it can result in insufficient material wet-out or inconsistent dispersion. Therefore:
A (air conditioning): Acceptable
B (decreasing mixing time): Not acceptable
C (shading): Acceptable
D (spraying water): Acceptable
