Cement – a material that bringeth construction on a new level of quality. Construction companies and factories for the production of cement is still conducting research and development material of higher quality. With the help of scientists cement is cheaper, greener and more durable. Using the latest scientific achievements in chemistry and construction, cement powder from primitive ancient turns into a high-tech mix, affordable and indispensable in the life of modern cities.
