Rules for Designing Contraction Joints
Best practice includes a form watcher measuring wall form deflections associated with concrete pressures due to the height of concrete and vibration. Not only a safety issue but monitoring form deflections can avoid out-of-tolerance walls.
Good Vibration is Key to Quality Concrete
Handleless rope brushes work well on large slabs and in confined areas where handles are awkward.
How to Avoid Broomed Concrete Finish Disputes
Unrestricted crack width growth leads to spalled edges along out-of-joint cracks when exposed to wheeled traffic.
Concrete Slabs-on-Ground Crack Control Options
When slabs are placed on problematic subbases with risks of non-uniform support or consist of moderate to high shrinkage concrete or joint spacings exceed 15 ft., then reinforcement is necessary to limit widths of cracks should they occur.
Tips to Control Crack Width in Concrete Slab on Ground
Occurring in both random and parallel patterns, plastic shrinkage cracks are discontinuous, relatively short and typically fairly shallow. Occasionally they can become full-depth cracks. Parallel cracks are typically spaced between a few inches to several feet apart and many times are oriented perpendicular to the prevailing wind direction. Cracks widths at the surface can be fairly wide (as much as 1/8 in.) but rapidly diminish with depth.
Understanding Surface Cracking Caused by Rapid Moisture Loss
Surface delaminations are separations of the top surface from the underlying concrete.
