When account is taken fairly good insulating properties of aerated concrete products external walling structures are placed with thick masonry wall equal to the width of gas silicate blocks. Exterior walls can also erected from the outer layer of a ceramic block, used for architectural reasons. In some cases, when you need to build a wall with good sound quality, the wall can be built additional insulation cover. Click Dr. John Mcdougall to learn more. The internal walls of concrete blocks is recommended to design in two layers with a layer of sound insulation between units. Gas silicate blocks can also be used for construction basement walls, if the groundwater level below the floor of the basement. Basement walls are designed in direct gas silicate blocks jammed with glue vertical seams. Basement walls require high sealing of high quality materials. If you have difficulties with compliance with these conditions should be put basement walls made of concrete.

Wall, erected at an angle or vertically, you can connect with dressing components of masonry or butt. Enclosing kontstruktsii, disposable, required to bind only to the dressing. In such cases, at the level of overlap should provide a crown of concrete. Building blocks of cellular concrete, the joints with the walls of other construction materials, usually erected back to back. In this case, at the junction block elements to design a wall mount one layer by means of fixing links. Connecting links are also used when connecting walls of concrete blocks with capital envelopes.

The existence of the outer wall breaks warming layer distribution loads from the top floor to the bottom and cause stress concentration, which may give rise to the appearance of cracks on the wall, insulated cover. An additional cause of stress accumulation in the wall above insulated cover is the effect of fixing the slabs in the wall. To prevent the emergence of such cracks should be put into the seam of the floor slab reinforcing rod. In a series of openings for windows is a significant change in load. In order to prevent the nucleation of cracks in the weld must be under the last row of blocks of cellular concrete, put in a cement-filled facet two valves. If you load more than 0.7 column maximum load, such valves can be fixed and in the extreme layer of cellular concrete blocks. Depth is determined by the Bookmarks facility to find the specific characteristics of groundwater, as well as the presence or no basement. Aerated concrete can be used for the production of basement walls, but it is recommended careful protection against moisture from high quality materials. The advantage of such a solution, except for a single manufacturing technology and ease of insulation walls of reinforced concrete rim of the basement, is also a good purchase with no basement in order to further insulate the bearing walls. Surrounding area around the building so it is recommended to arrange to establish a full flow of incoming water from the building. For this round of construction necessary to build a zone of reinforced concrete slabs. Another solution is laying a large bed of gravel.

The history of using mushrooms began during Paleolithic times. Few – even anthropologists – to understand what impact had the mushrooms on the evolution of mankind. Fungi play a central role in the cultures of ancient Greece, India and Mesoamerica. Because of its enchanting nature, fungi have always evoked deep emotional responses: from adulation by those who understand them, to fear from those who do not understand. Fear of mushroom poisoning exists in every culture, sometimes reaching forms of phobia. The term 'mikofobiya' defines the fear and loathing of people and cultures in relation to fungi.

Examples of such crops are English and Irish. In contrast to mikofobnym, there mikofilichnye culture. They are located in Asia and Eastern Europe, these include Polish, Russian and Italian peoples. They have extensive experience in the use of mushrooms, more than a hundred names to describe their favorite species of fungi. Evidence of a very significant role of fungi in the mythology and – increasingly – in the culture should be considered as the emergence of a special science etnomikologii. Work of an American scientist, RG Wasson and his successors allow to reveal the value of fungi in many cultural and historical traditions. In particular, mushrooms often appear as a classifier, with which well-formed opposition such as "profane – sacred," "Female – Male", "water – the fire", etc. Continuing in the tradition of grassroots fluctuations against fungi belonging to the plant or animal life explain a number of mythological motifs associated with the metamorphosis of the mushroom (The origin of fungi from the stone, turning people into mushrooms, etc.).
