THERE’S NO REASON TO CRACK UP OVER ... - Concrete Trends

Mar 06,  · The most common cracks in slabs are random drying shrinkage cracks. After placement, as the concrete dries out, it shrinks about 0.06% but the concrete’s capacity to resist this is only about 0.015%. The cracks form because of restraint – anything that prevents the slab from moving freely, such as the subgrade, creates restraint.

This research aims to produce non-structural concrete with mixed recycled aggregates (MRA) in upscaled applications with low-cement content. Four slabs were executed with concrete made with different ratios of coarse MRA (0%, 20%, 40% and 100%), using the mix design, the mixing procedures and the facilities from a nearby concrete production plant.
