Applications of Cement
Cement is the key ingredient in concrete that, when mixed with water, acts as the glue that binds the coarse and fine aggregate together to create concrete. The reaction with water is what makes cement an hydraulic material and gives concrete the essential versatility to be placed in a plastic (flowable) state and then harden into a strong ...

Types of Concrete Mix for Any Project
To know when your concrete is ready, use the back of a shovel to smooth the surface. Then make a groove in it with the side of the shovel. If the surface stays smooth and the sides of the groove hold their shape, your concrete is ready. If you can't make a distinct groove, add more water. If the groove caves in, add more dry ingredients.
