Concrete is used in just about every type of construction and when installed properly, it can provide a solid foundation to build on, or a finished product designed for an aesthetic appearance. We know how to determine the properties required for its intended purpose, but careful attention is required to ensure the finished product actually has those desired properties. When flaws appear in concrete slabs due to errors in the process of its placement, it will likely show up as one of the following: blisters, cracking, crazing, curling, delamination, dusting, efflorescence, pop outs, scaling, or spalling. These imperfections can be minimized or prevented by using proper concrete placement practices.
