The Chemical Composition of Concrete
Concrete is actually a mixture of cement (the binder), water and some form of aggregate (the filler). This means that concrete is a composite material. In addition to this, cement is also a compound material, as it is a mixture of limestone and clay.

Curing concrete’s carbon curse
Before you even install any equipment, the building itself has already created tons of carbon dioxide and added to global warming - thanks to the concrete in the walls and floors. Concrete is the second-largest source of greenhouse gases on the planet, contributing eight percent of the world’s CO2 emissions, making it a worse polluter than the airline industry.

Portland-Limestone Cement
Modifying a concrete mix design to replace higher carbon materials with lower carbon ingredients is an effective strategy to reduce its environmental footprint. Whereas the U.S. standard for portland cement allows for up to 5% of clinker to be replaced by limestone, the standard for blended cement allows for 5% to 15% limestone replacement in PLC (Type IL).

Limestone-based Overlays are a Regional Phenomenon
The limestone overlays I looked at had an average 28-day compressive strength (ASTM C-109) of around 5,000 psi at ¼ inch thick when placed over a sound 4-inch concrete substrate. This is significantly stronger than most stampable overlay systems. The limestone aggregate also plays a part in creating the distinctive look these systems produce.

Understanding Limestone in Cement
The limestone acts as a seed crystal for the cement, better distributing the reaction products and increasing the reactivity of the cement. As there is always unhydrated cement in the concrete, this change will have no real measurable effect on the use of fly ash. The cement might have a reduced water demand, and the coarser cement gradation
