There is a wish that own house was beautiful, comfortable, strong. Many choose the shell rock (rakushnyak) created by the nature from variety of construction materials. Only at the same time it must be kept in mind some features of material then not to be upset, feeling sorry for the spent efforts.
Advantages of shell rock as construction material
Shell rock is natural material therefore along with wood is eco-friendly material. It has good heat-insulating properties because of porosity therefore in the summer with it will not be hot. In air small amount of salt and iodine is distinguished that is useful at some diseases. Shell rock is rather strong for construction of one-two-storeyed buildings. If it is extracted near you, then and its price will be much lower, than, for example, brick. And at last, shell rock is simply beautiful!
Shell rock shortcomings
Shell rock even from one pit can have different structure and density. So, and durability of such blocks will differ. It is necessary to choose very carefully blocks for construction. If material is not processed or has cracks, it is necessary to process in addition it for durability. And it is considerable waste of time, forces and means. This natural material in itself differs in fragility that demands extra care in work with it.
Availability of the shortcomings given above has led to the fact that it is possible to build of shell rock only houses of small number of storeys. For construction of high walls and in need of construction of heavy overlapping, it is necessary to strengthen walls in addition. One more lack of the considered material can be considered its fragility at high humidity. In other words, in arid climate shell rock is durable, and in damp demands protection outside as it easily absorbs moisture. It is possible to revet, for example, it with brick and to plaster. The same should be made and in case the cold winter is necessary - shell rock will not sustain low temperature, one layer of the block will not be enough, at home it will be cold. It turns out that it is necessary to spend for warming of the house in addition. The porosity of material leads to excessive consumption of solution in the course of laying of walls, all stucco work can be carried out only in the summer as if in time of shell rock water freezes - it will be destroyed. The fragility of material does not give the chance to transport it on long distance - fight is formed too much, besides process of transportation leads to rise in price - to cost transportation costs increase. In order that externally shell rock looked adequately and did not demand facing - it needs to be processed. Do not build fireplaces of it and do not put the furnace - at high temperatures it quickly collapses. In a word, it is necessary to consider all features of the area where construction is planned. If you have warm winter, dry hot summer and it is necessary to construct quickly the house, shell rock will help out you and the built house will not be of a lower quality next and than properties. Besides the new technologies allowing to improve material properties without essential expenses of time and finance are now used. For example, impregnating shell rock with special solution, do it waterproof. And the brick received by its pressing is considered the best.
