Abstract

The article is devoted to the use of modifying additives into the concrete mix during the construction of multi-storey buildings. Additives accelerating concrete hardening allow it to quickly build upper floors, but increase the cost of concrete mixes. Thus, reduction of the holding time will not be cost-effective if concreting is not a leading process in scheduling. To determine the effectiveness of additives, the schedule of construction of a multi-storey building with a reinforced concrete frame was optimized. The main optimization methods are changes in the construction technology taking into account the use of various types of additives (superplasticizers, waterproofing additives; season; the method of lifting concrete mix to the floor). Relamix-M2 and Penetron - Admix" reduce the concreting time by 37%; the cost of one m3 of concrete decreases by 2.5%.
