- Abstract
- The results of eleven exploratory and four full-scale fire-endurance tests on reinforced concrete floors are given. All the slabs were monolithic and were made with gravel aggregates; six consisted of slabs cast to engage the tops of precast lightweight concrete joists. The effects of moisture content, aggregate type, and soffit protection are discussed. A general equation for the relation between slab thickness and fire resistance for different aggregates is proposed.
