小掺量矿渣粉对混凝土劈裂抗拉强度的影响

Influence of the slag power small dosage quantity on splitting tensile properties of concrete

以15%以下的小矿渣粉掺量为对象进行试验研究,将掺有不同掺量矿渣粉的混凝土进行劈裂抗拉强度试验;比较几种小掺量对混凝土劈裂强度值的影响。通过试验得出:在小掺量范围中,混凝土劈裂抗拉强度随着掺量的增加呈现先增加后减小的趋势。

To small slag powder content below 15% as the object of study,will be mixed with different slag powder concrete splitting tensile strength test; comparison of several small dosage on the concrete influence of splitting strength. Through experiments： in the small dosage range,concrete splitting the tensile strength increases first and then decreases the increase in volume.
