Abstract:
The compressive strength of concrete, as well as the strength development, are one of the basic parameters used in the design of concrete structures, as well as determining the dynamics of the casting concrete. Given the wide range of benefits provided by the application of self-compacting concrete, it is very important to know the influential parameters on its properties. The paper presents own experimental research, carried out on 14 types of self-compacting concrete. The influence of different types of additives and aggregates of different origin on compressive strength of the concretes at ages 2, 7, 14 and 28 days were analyzed by statistical methods. The research showed that the compressive strength of self-compacting concrete is dominated by the use of recycled aggregate and fly ash, in relation to natural aggregates (river, crushed and their combination), lime and other parameters. Strength increment functions with very strong to almost perfect correlations have been established.
