On concrete and mortars

Materials phase as that changes, may absorb excessive summer heat and thus provide a comfortable room temperature. This means that the cost of air conditioning can be significantly reduced, while the right sailing - and completely excluded. Company H + h Celcon, which manufactures concrete products, first placed Micronal PCM - phase-state material, which changes from BASF - to the blocks with cement vspenennoho. This greatly increased the ability to block teploakumulyuyuchu Celbloc Plus, producible by this company. Due to porous structure of concrete building materials have excellent thermal, sound-proof and heat-resistant properties. The additive material with the phase as Micronal PCM, which changes, enhances teploakumulyuyuchu ACT sobnost vspenennoho concrete and therefore also constructed buildings from it.

The new production of wall blocks in size 500h200h300 mm arbolita in August this year, started work at full capacity in the Pskov region. It opened the Russian company "Dobrodyeyi", the press service of the company. Arbolitovyh similar industries in the country until very much. The main supply of Pskov arbolita will focus on building low environmental teplosberehayuschyh buildings in Moscow region and close to its regions. The volume of production, calculated monthly support several construction projects. The new website "Dobrodyeyi» arbolit.net provides comparative characteristics: cost of materials for the building of arbolita 2-3 times lower than in the house of bricks, in the same time lower the cost of installing a building that comes with arbolitovyh blocks. Using arbolita to get elnuyu means saving money and building materials during construction, which is especially important in conditions of rising prices and shortages of mineral resources for their production. Arbolit (GOST 19 222-84), or as it is called, derevobeton increasingly positioning experts as a promising material, though known for a long time.

Ability to build facilities in the shortest possible time is one of the most important factors in modern construction. Another role plays and such criteria as cost of the work. New low-rise building construction system, developed by German company "Hebel Magdeburg GMBH & Co. ", To fully meet these requirements. The system is based on the use of large blocks of penobloka. Since penobloka made only from natural components - quartz sand, destroy, cement and water, it rightfully belongs to the category of environmental issues. Blocks izhotavlyayutsya with patented technology that provides education since the structure of the material.

In the article "On the pre-stressed reinforcing bars highway bridges" ( "Construction and real estate" № 18, 16.04.2002, pp. 6) brought the hard way prefabrication reinforced concrete bridge beams with regard navivky perednapruzhenoyi strings (high-wire) in the ribs on the sets of beams pair of internal final and intermediate anchors suggested by the authors. This consistent reinforcement layers are formed symmetrical and asymmetrical stretches napruzhuvanoyi threads by patent number 3672 RB, shifted relative to each other in the even and odd layers of sutures. In the known technical solution "Belhyprodora" reinforcing 15 m bridge beams made of three separate beams located at different altitudes on the cross beams.

Joint report of the Head of the Laboratory designs NIEPHP "BELNIYIS" In. N. Belovicha and chief scientific officer NIEPHP "BELNIYIS, bearing, PhD Professor BHPA P. V. Alyavdina "features multi-frame structural systems of buildings, developed by experts" BELNIYIS, and the results of field studies, made them September 22 in the international scientific-technical conference "The multi-storey residential buildings with monolithic and prefabricated monolithic frameworks. - Prefabricated monolithic frame-frame svyazevyy mVb-01 is an open unified residential and public buildings mass destination, - said St. N. Belovich. - The frame is designed in BELNIYIS on the basis of conducted complex research, experience, experimental design and construction of multi-purpose building mass. The structure consists of frame-mounted or monolithic concrete circles onny and missed them through monolithic beam bearing and svyazevyye uniting teams bahatopustotni plates in flat discs overlap. At the ends of boards are open cavity in which a depth of 10 plus or minus 2 cm visiting Concrete Dowels, made with concrete in accordance with the bolt, bearing. On the sides of plates on the length of 15 plus or minus 2 cm can be issued working equipment. Frame, referred to - the news, use is in construction just begun. Therefore, very seriously have before it the factual data about its behavior under load in various designs, but also in the process of further improvement.
