Abstract
The paper presents results of investigations on influence of domestic complex chemical additive containing structured carbon nanomaterial and characterized by combined (curing acceleration and plasticizing) effect on concrete curing kinetics in non warm-up version of monolithic concreting technology. Standardized and original methods have revealed experimentally regularities in increase of strength for heavy cement concrete under the influence of specific accelerating UKD-1 additive component and the additive itself according to its dosage (within the range of 0.5–2.0 % of cement mass). Growth rate dependences for the concrete with UKD-1 additive on basic technological factors: cement quality, water-cement ratio value, concrete composition and concrete mixture consistency, curing environment temperature and heat-insulating characteristics of shuttering blocks have been evaluated in the paper. Such approach has made it possible to substantiate rational modes and parameters of conditions for concrete curing with the UKD-1 additive in order to ensure strength (under compression) in the 50–100 % range of the required value at the project age of 28 days without energy consumption for acceleration of its curing.
