Use of Limestone Blocks in Constructions in the Republic of Moldova

Abstract One of the most important problems in modern society is the problem of using natural, ecological, harmless products for humans. In construction, this problem is solved by selecting, combining and using natural, traditional materials for some geographical areas. The most widespread in the world, starting from antiquity, is limestone. The limestone block, the so-called „cotileț”, is a construction material that has been used in masonry for over 60 years on the territory of the Republic of Moldova. In this research is considered dynamic extraction of limestone blocks, are analysed existing excavations and its location, the limestone reserves in Moldova. The technical characteristics of the „cotileț” are studied, such as dimensions, density, water absorption level, softening coefficient and earthquake resistance. At the same time, the existing buildings on the territory of the Republic of Moldova were examined and the characteristics of those built of limestone blocks were highlighted.
