改性硅灰石粉对砂浆早期抗拉强度的影响研究

Research on Influence of Modified Wollastonite Powder on Tensile Strength of Mortar at Early Stage

研究了盐酸对不同细度的硅灰石粉改性后,硅灰石粉及其掺量对砂浆早期抗拉强度的影响,结果表明,掺入改性硅灰石粉体的砂浆与空白试件相比,3d的抗拉强度最高可提高73%,可以认为改性硅灰石粉在砂浆中具有较高的活性。

The research on the influence of wollastonite powder and its mixing amount on the tensile strength of mortar at early stage is made after the modification of hydrochloric acid on wollastonite powder of different fineness. The results show that,comparing with the mortar by mixing modified wollastonite powder and blank test piece,the tensile strength in 3 days can enhance 73% at most. Therefore,it is considered that the modified wollastonite powder has higher activity in mortar.
