Flowforming technique with plastic concrete mix designs – The application of pre-stressed concrete hollow core slabs in the industrialized construction was banalized to a certain extent until recent years, because they were repeatedly produced with the same concrete mix designs, cross sections and thicknesses. The progress in the development of the advanced pre-stressed concrete elements due to the availability of concrete admixtures, namely superplasticizers and water reducers, has led to a situation where the performances brought by the modern products compare to the legacy pre-stressed concrete elements like clay for ceramics to compacted beach sand. The plasticity of the concrete results in countless advantages in productivity, production costs, available market, lean construction and introducing mechanisms of additional shear at no extra cost.
