石屑砂浆性能研究

Study on behavior of stone chips mortar

本文对比研究了普通砂浆和石屑砂浆的性能 ,研究表明 ,石屑砂浆具有较好的和易性 ,较高的抗压强度、弹性模量和抗冻性 ,但收缩比普通砂浆大。最后 ,本文给出了石屑砂浆 2 8天强度 (R2 8)与灰 /石屑 (C/S)

This paper evaluates the behaviors of stone chips mortar in comparison with natural mortar.It is demonstrated that the stone chips mortar has better workability,higher strength,elastic modulus and frost resistance,but more shrinkage.At last,the paper provides the empirical formula of f 28 ～C/S.
