This paper provides an experimental investigation to study the effect of using different types of reinforcement on the flexural behavior of ferrocement thin hollow core slabs with embedded PVC pipes. Twelve slabs of 1100 × 400 × 55 mm dimensions were casted and tested till failure. The effect of four different types of reinforcement was investigated in this study including; steel wire mesh, macro and micro steel fibers or a combination of both, steel bars and CFRP bars. The results showed that the slab reinforced with only macro steel fibers provided the highest flexural strength, while that reinforced with steel bars showed the highest stiffness and lowest deflection among all tested slabs. Also, the dry design density for all the hollow core slabs was determined to be below 2000 kg/m³ which is within the requirements of light weight concrete as set by most codes of practice.

本文提供了一个实验研究，以研究使用不同类型的钢筋对嵌有PVC管的钢筋混凝土薄空心板的抗弯性能的影响。浇铸了十二块1100×400×55 mm的板坯，并进行了试验，直至失效。在这项研究中，研究了四种不同类型的钢筋的效果，包括：钢丝网，大型和微型钢纤维或钢筋和CFRP钢筋的组合。结果表明，在所有测试板中，仅用粗钢纤维增强的板提供了最高的抗弯强度，而用钢筋增强的板则具有最高的刚度和最小的挠度。另外，所有空心板的干法设计密度均确定为低于2000 kg / m ^3。 这在大多数实践规范中都符合轻质混凝土的要求。
