WebbA key rheological indicator for the slipform paving process is the slump measurement. As typical slipform paving concrete mixtures are designed for slumps around 10–40 mm [1], variability in the free water can significantly affect both the rheology and strength.Sources of this variability include, for example, aggregate moisture, grey water left in mixer drum, … WebbWorkability : Placing condition of concrete governs its workability, low – slump of 25-75 mm (lightly reinforced sections in slab, beam, column) to high – slump of 100-150 mm (slip form, ...
