Engineers from Far Eastern Federal University Military Training Center (FEFU, Vladivostok, Russia) together with colleagues from RUDN University have developed a concrete mixture with nano additives for monolithic construction up to ten stories high.

The concrete casting is possible within a very humid climate and negative temperature down to minus 5-degrees centigrade. Given that, the constructed buildings will not require major renewal for 50 years. The related article is published in Construction and Building Materials Casting concrete under low-temperature conditions is a serious challenge for the construction industry.

If the water in the concrete freezes, the fluidity of the concrete goes wrong, which will foul its curing and.promote in-slab lumps forming. Casting at temperatures below plus five degrees already requires special technology. Breach of one leads to reduced characteristics of monolithic structures that deteriorate prematurely.
