Abstract
This article presents the low-temperature hardening parameters of concrete with complex admixtures, including a polycarboxylate superplasticizer and an air-entraining admixture. It was found that the use of a polycarboxylate super-plasticizer and an air-entraining admixture in concrete allows for a reduction in isothermal heating time from 5 hours to 3 hours and an isothermal heating temperature from 60°C to 40°C, while ensuring high hardening intensity and strength gain after 7 days of 80–84% of the design strength, and at 28 days, a 15–20% increase in the strength of air-dry concrete without the admixture. A complex admixture containing Hidetal GP-9-Alpha and Hidetal P8 is more effective in low-temperature hardening than the complex admixtures Stahement 2000M and Microporan. Polycarboxylate superplasticizers have been shown to enable the use of reduced and low-temperature HTT regimes, which will reduce energy costs and the risk of structural defects.
