Putzmeister mortar machines in Moscow residential building project
Moscow is a construction site that never stops moving! A program for the demolition of five-storey tower blocks is currently underway, whereby dilapidated buildings will be making way for modern residential blocks with social infrastructure.
At the start of the 1950s, the Soviet government set itself the target of developing mass residential buildings while simultaneously saving state funds. The idea was adopted from the French prefabricated construction method, where the kitchen was 5 – 6 m2 in size, the toilet was located in the bathroom and the bedrooms were small.
Khrushchyovka - a resounding success
In 1953, a resolution was passed to construct 283 buildings containing these simplified residential units for labourers. The project was a success: Up to 1970, 400 million m2 of living space were created in these five-storey Khrushchyovka buildings. In terms of construction speed, Moscow was one step ahead of all the major cities in the Western world.
Renovation work falters
The renovation of the Khrushchyovkas was planned for 1980 but was delayed due to the volatile political situation at the time. The restoration work finally started in 1999 and was scheduled for completion in 2010. The inhabitants of 1,722 five-storey buildings were promised new homes, while 6 million square metres of living space was scheduled for demolition. The initial plan was to construct a new building in the same district and then demolish the old building, at which point another new building was erected. Until 2007, everything was going according to plan, but the speed of construction slowed as the economic crisis deepened and all projects eventually ground to a halt following the approval of amendments to the Russian Land Code. The developers and construction companies were no longer able to meet their targets, which is why the government made the decision to finance the program from the municipal budget.
Putzmeister mortar machines – a guarantee for successful working
257 buildings are under construction at the present time. Almost all of them are being built using Putzmeister concrete pumps and mortar machines.
Just one example: A construction site in the northwestern administrative district of Moscow
The construction of the residential district was financed from the municipal budget and implemented according to the individual draft. The project was completed in 2014. The overall surface area is 35,000 m2, of which 22,000 m2 is habitable space. The four buildings (7, 9, 11 and 14 storeys) incorporated a total of 356 apartments. The developer is the administrator for civil construction. This residential district is almost finished.
Modern type M 740 D and M 760 DHB screed conveyors were used for the screed-laying work. Altogether, more than 9 mortar machines were involved in this project and sometimes had to overcome delivery heights exceeding 40 m. The Mixokret M 760 is the most powerful Putzmeister screed conveyor and is used for mixing and conveying sand, gravel and fine grained concrete with a maximum grain size of 16 mm. Putzmeister customers made a conscious decision to rely on quality "Made in Germany". All core components and assemblies of the Mixokret were developed and manufactured in Germany. Putzmeister technology helps decrease construction times and reduce costs for materials and labour. The Putzmeister brand represents high resale values and good service. The earth-moist screed laid in these residential districts has different functions.
The screed creates a level surface, can withstand heavy loads and serves as a basis for the construction of additional floors. Screed also provides an insulating layer that guarantees additional home comfort in the winter. In many residential buildings in Russia, the tiles are laid directly on the concrete surface and there is a danger that cracks will form during freezing conditions. According to feedback from our customers, they are extremely satisfied with the Putzmeister technology. "Since arriving, the technology has operated flawlessly and without stopping" remarked one of the team leaders on the construction site.
