Freeze-thaw Cycles and Concrete Grinding. Because concrete is porous, it absorbs water. When the wet concrete freezes, that water expands and causes the pores of the concrete to pop. Over time, this expansion due to freezing and thawing, then refreezing, causes damage to the concrete slab. When the surface of the concrete is ground down, …

What are the differences in these cement types and how are they tested, produced, and identified in practice? In the most general sense, portland cement is produced by heating sources of lime, iron, silica, and alumina to clinkering temperature (2,500 to 2,800 degrees Fahrenheit) in a rotating kiln, then grinding the clinker to a fine powder.
