Precast Self-Compacting Concrete (PSCC) is one of many types of approach in Industrialised Building System (IBS) that were used to speed up construction to meet consumer’s demand. The usage of Self-Compacting Concrete (SCC) will profit in many ways such as faster construction, reduction in manpower, easier placing, uniform and complete consolidation, better surface finishes, improved durability, increased strength, and safer working environment. The addition coir fibre in PSCC can improve the tensile strength and flexural strength in the concrete mixture.by combining the two elements of SCC and CF in PSCC slab panel, the desired structural behaviour can be achieved. The four-point bending test was conducted on the all 4 type of PSCC slab panel that is solid control, solid CF, hollow control, and hollow CF. The solid PSCC-CF slab panel has the best structural performance compared to the other 3 other PSCC slab panel. The crack and ultimate load of the solid PSCC-CF slab panel recorded are 24.5 kN and 35 kN respectively compared to the reading collected from the other 3 slab panels. The crack propagation on the solid PSCC-CF slab panel also less propagated due to the addiction of CF that build concrete bridges. The load-deflection profile of solid PSCC-CF slab panel also shown the best result compared to the other slab panel. The load-strain profile recorded also shown the highest values of 105 micro strain on top and 53.14 micro strain on side of solid PSCC-CF slab panel.

Reinforced concrete structure is inevitable from cracking. The material properties of the concrete itself, which is brittle, causing the concrete to have low tensile strength. Hybrid fibers that used in this study were coir fiber (CF) and steel fiber (SF). The purpose of the fibers was mainly to control the cracking of concrete. In view of this, a computational study was carried out to determine the structural behavior of Precast Foamed Concrete Slab (PFC-CF-SF) containing hybrid fibers under flexural load. Parametric study of PFC-CF-SF with various slab’s thicknesses and length was conducted. The slabs were subjected to flexure load until failure. The ultimate load, load-deflection midspan, and stress distribution of the slabs under flexure load were recorded. To validate the slab model using finite element analysis (FEA) in ABAQUS software, the results recorded from finite element model simulation was compared with the experimental results. From FEA, the result of PFC-CF-SF slab and experimental work was validated with difference of 6.13% ultimate load, and 7.01% difference in load deflection midspan which is in acceptable range of ±10%. The parametric studies of PFC-CF-SF with different length and thickness showed decreasing value of ultimate load capacity and higher deflection with the increment of length. Despite that, an increasing of ultimate load value and declining of deflection was showed with the increasing of slab’s thickness. This study proved that PFC-CF-SF was more ductile than plain foamed concrete with higher ultimate load bearing capacity and the usage of fibers in foamed concrete slab was able to control the crack propagation.
