摘要
Abstract
To test properties of the self-compacting concrete containing reclaimed asphalt mixture (RAP),slag (S),and coal ash (F),the experimental study is performed respectively for properties of the self-compacting concrete containing different amount of RAP and different mineral additives (coal ash and slag) by slump and compressive strength tests.The results show that RAP has small impact on the slump of the self-compacting concrete while the mineral additives have larger impact;with the increase of the RAP,the compression strength of the self-compacting concrete reduces gradually,and the mineral additive does not significantly improve the strength.Finally,regression analysis is performed for all compressive strength data to the obtain a compressive strength prediction model for self-compacting concrete based on independent variables such as RAP,coal ash (F) and slag (S).关键词
