Facts About Concrete conspecinc

can see concrete can be ordered in many ways to suit a particular appliion or job description. It is important to know the longer the hydration or curing time = the stronger the concrete! Thats why people tell you to water the concrete after it is finished. The best way to cure concrete however, is to apply a curing compound.
