Frost resistance of heavyweight self-compacting concrete

Abstract

Self-compacting concrete (SCC), a non-shaped composite building material, has improved microstructure packing, strength, and durability thanks to the use of fly ash, a highly effective mineral additive. Performances of SCC with fly ash and conventional SCC with limestone filler were compared. Additional experimental self-compacting concretes were made and adjusted with various types of fine aggregates, fillers, and unique additives to increase freeze-thaw resistance. The relationship between the proportion of barite sand and additives and the properties of SCC was investigated and discussed. Tests of freeze-thaw resistance with and without de-icing salts are the main focus of these articles.
