The world's foremost resource on decorative concrete
Many often use compressive strength — the ability of a material to withstand compression or pushing it together — to determine mortar and concrete’s quality. This makes sense for floors and overlayments as the primary forces applied to them are downward, compressive loads from traffic, equipment or anything affected by […]
What is the most important test when it comes to evaluating decorative concrete overlays? A case can be made that any test result can help better define how a product will perform, but when it comes to decorative overlays some tests are more meaningful than others.
Interesting explanation for why ancient mortar has lasted long.
How strong do concrete countertops have to be? The answer is not a simple one. It depends upon how you define strength, what your intended use is and your sealer choice.
Most decorative concrete contractors know that consolidating concrete is as essential to a quality finished product as mix ratio or proper finishing and curing. Consolidating forces air out of the concrete and encourages aggregate to rotate and fit together tighter, creating stronger concrete.
Treating concrete with densifiers increases compressive and tensile strength while adding moisture- and abrasion-resistance.
