Fire Resistance of Concrete Structures

determining fire resistance of concrete walls. Table 2.1 from ACI 216, repro-duced here, provides the minimum equiv-alent thickness required of a concrete wall based on aggregate type to achieve a fire resistance rating of one hour to four hours. For solid flat concrete walls, the actual thickness is equal to the equivalent thickness.

Lightweight Concrete - What Is Lightweight Concrete And ...

The light-weight concrete density is less because lightweight coarse aggregates and sometimes lightweight fine aggregates are used, which make the concrete weigh less. The lightweight aggregates used are usually expanded shale, clay, or slate materials that have been fired in a rotary kiln to give them a porous structure, similar to volcanic rock.
