In this paper, the properties and the behavior of limestone cement concrete and mortar are studied. Portland limestone cements of different fineness and limestone content have been produced by intergrinding clinker, gypsum and limestone.
The strength of the concrete is inversely proportional to the water/cement ratio. In other words, the more water you use to mix the concrete, the weaker the concrete mix. The less water you use to mix the concrete, the stronger the concrete mix.
There still seems to be some confusion about whether fine limestone in cement (up to about 5% as permitted by eg: US and European standards) is an inert filler, or whether it is chemically reactive and contributes to the cement hydration products.
Limestone is also used as a pigment in toothpaste. In addition to the value of limestone slabs quarried for building materials, limestone is also used in cement. A discussion about cement requires a distinction between cement and concrete: although the two terms are often used interchangeably.
