Rainscreen Principle Natural stone is gaining increasing popularity as a material harnessed to create dramatic and high-performing rainscreen faades. Stone panels are installed onto the building face using either a concealed system or an exposed clip system. Stone-clad rainscreen faades are most commonly back-ventilated and consist of an interior drainage cavity, which helps swiftly.

2020-6-2The raw materials needed to produce cement calcium carbonate, silica, alumina and iron ore are generally extracted from limestone rock, chalk, clayey schist or clay. Suitable reserves can be found in most countries. These raw materials are extracted from the quarry by blasting. They are then crushed and transported to the plant where they are stored and homogenized.

3. The Use Of Lime Has Ecological Benefits. Lime has less embodied energy than cement. Free lime absorbs carbon dioxide in the setting process of carbonation. It is possible to produce lime on a small scale. The gentle binding properties of lime enable full re-use of other materials. A very low proportion of quicklime will stabilize clay soils.
