The durability of glutinous connections of the wood maintained in various climatic conditions, first of all depends on degree of water resistance of polymer on the basis of the pitch, glutinous connection used as a basis.
However now by the term "water resistance" of glutinous connection of wood mean exclusively its residual durability after hydro-and […]
Traditionally for manufacturing of bearing wooden designs use rezortsinoformaldegidnyie or fenolrezortsinoformaldegidnyie glues, otverzhdaemyie in the cold method at introduction of settlement quantity of paraformaldehyde. Depending on climatic operating conditions or character nagruzheniya designs glues can be modified combination of a thermojet basis with thermoplastic additives, for example, polivinilatsetatnoy a dispersion, introduction organic napolniteley – synthetic […]
Working out extending knitting, increasing in volume in process tverdeniya, and especially straining cement (NTS), allows not only to solve indemnification problem usadki, but also to supply at concrete expansion on its basis a simultaneous tension possessed in it and saving with it armature coupling. Thus in concrete arise pressure of compression counterbalancing them - […]
In building heat-shielding and noise isolation problems always were traditionally priority. The energy crisis of 70th years in Germany has led to system engineering teploizoliruyuschih windows as one of directions energosberegayuschih technologies. An innovation consequence was essential increase of humidity in premises. High humidity there — the reason of occurrence of mustiness, reproduction of colonies […]
In world practice some methods of restoration of the worn out pipelines without razryitiya tranches are known, three technologies are practically most fulfilled.
Technology of drawing on an internal surface of the repaired pipeline of cement-sandy cover. The technology of similar protection industrially separate metal pipes was known since 1836 After 100 years a method […]
heat-avant-guard Is a complex system of warming of outside walls of the under construction and already constructed buildings on the basis of the tested materials of a choice quality of the Russian production. The system is developed at use of the most progressive decisions of world technology and corresponds GOSTam. At its application heat concentrates […]
Energosberezhenie begins with the base. At separately standing cottage in the absence of a thermal protection of basement walls and a floor to 20 % of all teplopoter can have on a cellar zone.
To have possibility subsequently to change character of use of a basement, it is necessary to provide for a design stage a […]
Increase energoeffektivnosti buildings the last decades became one of the basic directions of development of the building industry. The beginning abroad of workings out on improvement of a heat-shielding of maintained buildings was a consequence of an energy crisis of 70th years, and since 1976 in the majority of foreign countries rationed sizes of a […]
Cement - one of the most demanded construction materials. 75 % consume it factories ferro-concrete and asbestotsementnyih designs, 15 % go on building and about 5 % is sold at retail.
Cement is a base material for production of ready designs so, buildings, plus it is an irreplaceable material for building of the bases, socle and […]
Mineral cotton wool on the basis of a basalt fibre is popular among builders and its consumption grows. According to the interrogation conducted by the author of the article, demand for stone cotton wool has grown lately on 15-20 % and has stable prospects of the further growth. Some experts result higher figures.
Unlike others mineralovatnyih […]
The modern person lives in the world of sounds. In urban houses and offices indefatigably (and at times loudly enough) crack radio leaders, overstrain TVs, plays music, continuously call phones and pagers, and also hoots, buzzes, peeps and the weight of the diversified engineering ticks. Alas, we have already got used to fall asleep under […]
The modern market izolyatsionnyih materials is dynamical enough. Requests to building isolation vary. Are revised SNiPyi, as a rule, towards increase in requests. Customers and consumers increase energosberegayuschie parametres of the objects. The market teploizolyatsionnyih materials in the answer constantly expands range of the offered goods. Properties of already known materials are changed and improve.
Some […]
The space architecture became today the conventional branch of an architectural science and practice. Its lessons merge with the basic stream of architectural ideas and trends, influencing on methods of designing, building and views. Sary Heart is informed on it in the article «There Is North Arrow in Outer Space» (Sara Hart), published in December […]
Unlike shaggy divine creatures to our person that nothing to freeze during winter colds, it is required having warmed up internal and heating outside. Than it is more odezhek on itself you will pull, the mnogosloyney the winter dress, the longer and it is easier saved warmly. But with layers, as well as with heating, […]
The moisture, in a problematics of protection and cultural heritage resumption, is one of the greatest problems. It directly or indirectly influences destruction of all materials in a design. The purpose of the given text not is detailed transfer of every possible methods of sanitation of a moisture, and a reminder on some decisions applied […]
