Embodiment Construction
[0044] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0045] The invention provides sleeve grouting material mixed with iron filings and fine sand, its preparation method and matching strength detection method. This application uses processed iron filings fine sand to replace the aggregate in the original sleeve grouting material, which can greatly improve sleeve grouting after use. The strength of the sleeve grouting material, because this application is mainly prepared with pig iron filings, so the cost is low, and the prepared sleeve grouting material can be analyzed and tested in real time to ensure product reliability through compressive strength.
[0046]As a specific embodiment of the sleeve grouting material mixed with iron filings fine sand of the present invention, the sleeve grouting material of the present invention includes the following components in parts by weight: 100 parts of cemen...
