The moister of plastic concrete is reduced by evaporation, formwork absorption, and seeping. The result of moisture loss caused increase of negative capillary pressure in concrete that increase tensile stress. Summary when it crosses the limit of tensile strength of concrete, it cracks. The tensile stress will cause cracking in early age concrete that is called plastic shrinkage cracking (PSC). PSC remains a serious concern, particularly in large surface area placements like slabs. Learning about crack analysis before rehabilitation and strength of reinforced concrete (RC) slab is important. In this paper, RC slab analysis has been done by using Artificial Neural Networks (ANNs). Feed-forward Back- propagation Neural Network (FBNN) was the selected network to generate prediction system with the minimum error and maximum squared correlation coefficient.
