Abstract
This state of the art report discusses parameters which influence quality and aesthetical impression of the concrete surface. The main focus has been on evenness of colour, occurrence of voids and pores and cracking due to drying shrinkage. Factors influencing the concrete surface such as material parameters, chemical admixtures, mix design, formwork, form releasing agents and production techniques are discussed. Test methods currently used for assessment of surface quality are listed. The characteristics of self compacting concrete are finally compared with ordinary vibrated concrete.The report is summarised with recommendations for further research. Beyond research, work is needed for the development of a Norwegian guideline covering concrete surface quality.
