No matter where you are in the urban landscape, you are never more than a few feet from cement. Cement forms the basis of virtually the entire worlds infrastructure. It is an impressively cheap binder that enables a wide variety of building materials. Despite its ubiquity, it is a surprisingly complex mixture of a balance of ingredients such as lime, silica, alumina and more. Knowing what is in your cement is a fundamental check of its quality and strength.
Starting on September 29, LECO launched a 4-part webinar series for an in-depth exploration of cement and other associated building materials.
