搅拌工艺对透水混凝土力学性能的影响

Effect of mixing process on mechanical properties of permeable concrete

研究了一次投料法、水泥裹石投料法、净浆裹石投料法三种不同的搅拌工艺,对于透水混凝土力学性能的影响,通过不同的第一次加水量研究,确定了二次搅拌投料工艺中最优的第一次加水量,实验表明采用二次搅拌投料工艺可以有效地提高透水混凝土的力学强度,以及通过改变宏观的投料行为,可以改变透水混凝土微观的界面黏结强度。

The three different mixing processes of one-feeding method,cement-wrapped stone-feeding method,and pure-stone-wrapping stone-feeding method were studied.Their effects on the mechanical properties of the permeable concrete were determined by different first-time water addition studies to determine the two-time mixing and feeding method.The optimal first-time amount of water was added.Experiments show that the secondary mixing and feeding process can effectively improve the mechanical strength of permeable concrete,and by changing the macroscopic feeding behavior,the microscopic interface interface bonding strength of permeable concrete can be changed.
