It is important not to confuse cracks from restraint of the concrete at early ages, to plastic shrinkage cracks. Plastic shrinkage cracks are generally tight, about 0.3-0.6 m (1-2 ft) long, extend down about 25-100 mm (1-4 in.) from the surface, and form in

Concrete Slab Surface Defects: Causes, Prevention, Repair

Cracks that occur after hardening usually are the result of drying shrinkage (Fig. 3), thermal contraction, or subgrade settlement. While drying, hardened concrete will shrink about 1.6 mm in 3 m (1/16 in. in 10 ft) of length. To accommodate this shrinkage and control the location of cracks, joints are placed at regular intervals.

Using Recycled Concrete Aggregate Specify Concrete

Feb 28, 2019  Crushed concrete has been in use since the ancient times, only to be integrated with gravel, sand, and cement to ensure durability. The practice was first recorded in the 1860s. US construction companies were reluctant to use the technique at first, since crushing cured concrete proved to be much more cost-intensive in terms of labor.
