掺入超细石灰石粉的混凝土性能研究

Study on Performance of Concrete Mixed with Ultra-fine Limestone Flour

研究了掺加磨细、超磨细石灰石粉的混凝土及砂浆的施工性能及力学性能。适当的掺量可减少混凝土坍落度的经时损失 ,提高混凝土强度。

Authors study construction performances and mechanical features of concrete and mortar mixed with ultra-fine limestone flour.Results indicate that proper quantities of ultra-fine limestone flour can help engineers to decrease the time-loss of concrete slump constant and to increase concrete strength.
