Studies at EPFL, have shown that a kaolinite content of only about 40% in a mixture of LC 350 (50% ground clinker, 30% calcined clay, 15% limestone, 5% gypsum) is sufficient to give mechanical properties comparable to the reference plain Portland cement from about 7 days (EN 1961 mortar bars w/c =, sand/cement = 3 ).A study of 46 clays from around the world has shown that there does not ...
Very highgrade limestone deposits with a calcium carbonate content over 95% are found in the Te KuītiŌtorohanga region. This limestone is quarried and ground to a variety of sizes with diameters ranging from a fraction of a micron to several microns (1 micron = 106 m). These fine powders find a multitude of uses as fillers in manufactured ...

Limestone pavements are large areas of exposed limestone. When the overlying rock was eroded the pressure release on the limestone below caused it to crack even more. Limestone pavements are characterised by large gaps between the rock, called grikes. .
Limestone is a common, chemical sedimentary rock formed primarily from calcium carbonate. It is generally lightcolored and can also include fossils of calcium carbonatecontaining organisms, like corals. Limestone can be found all over the world and is the major type of rock found in karst features (crystal cave systems found in bedrock).

Limestone powder (LP) was used as a compensating material with different ratio of cement include (0, 10, 15, 20, 25) %. Compressive and tensile strength were investigated before and after the exposure to high temperature including (200, 400, 600) °C. The study show that limestone compensate changes in both compressive, and tensile strengths.
