Admixture-modified non-air entrained and air-entrained self-compacting concrete

The influence of superplasticizer type, air-entraining admixture, anti-foaming admixture and viscosity modifying admixture on air-content, workability and time-dependent change of workability of self-compacting concrete (SCC) is analyzed in the paper. Frost resistance, durability coefficients and air-void parameters of hardened SCC are also investigated. The research results indicate that the admixtures significantly change the analyzed properties of fresh and hardened SCC.
