A study on the properties of the light weight concrete which performs surface coating of the coarse aggregates by using chemical admixture
The purpose of this study is to investigate the mechanical property of concretes using surface treated lightweight aggregate. Slump of concretes using surface treated lightweight aggregate measured 120~140mm, which are lower than slump of NWAC. Compared to compressive strength of NWAC, compressive strength of concretes using surface treated lightweight aggregate showed a level of 82.8~95.9%.
