Types and Causes of Concrete Deterioration

sion creates tensile stresses in the concrete, which can eventually cause cracking, delamination, and spalling (Figs. 1 and 2). Steel corrodes because it is not a naturally occurring material. Rather, iron ore is smelted and refined to produce steel. The production steps that transform iron ore into steel add energy to

Should I Use Stone Dust or Sand Between Patio Pavers?

Using Sand Between Patio Pavers. Sand between pavers will compact to a degree, yet still remain porous enough for good drainage. Typically concrete sand is used as a base layer and leveling medium for patios and walkways made of concrete paving stones. Once applied between the pavers, the excess is easy to sweep away.
