Influence of Cracks on the Properties of Self-Compacting Concrete

Abstract:

The paper deals with self-compacting concrete (SCC) and the change of its properties after exposure to thermal loading. Two types of microfillers were used (along with appropriate amount of superplasticizer) to gain concrete which would meet the requirements for SCC – limestone powder and fly ash. Specimens were subjected to temperatures of 600 °C for 2 hours. Results proved significant worsening of all studied parameters on samples after the thermal loading. Therefore studying of material exposed to different external conditions for better simulation of real life of construction is important in future research.
