Tóm tắt

Concrete containing ground granulated blast furnace slag (GGBFS) has many advantages but it is easily subjected to cracking and has low quality when cured in poor conditions. For sustainability of slag concrete structures, these disadvantages need to be overcome. In this study, the effectiveness of high alite cement (HAC) in improving cracking and quality of covercrete of slag concrete was investigated. Cracking resistance ability was examined by tensile strength of concrete; while surface water absorption test was applied to study the quality of covercrete. The results revealed the capacity of HAC in improving tensile strength of slag concrete. High bond strength between aggregate and HAC mortar contributed significantly to larger tensile strength. HAC slag concrete also exhibited a high resistance against water absorption. The results revealed the capacity of HAC in improving tensile strength of slag concrete.
