Sleeve grouting material mixed with
iron filings fine sand, its preparation method and supporting
strength testing method, this application mixes
iron filings fine sand sleeve grouting material, and the sleeve grouting material is measured in parts by weight and includes the following components:
cement 100 parts, 50-55 parts of modified mineral
powder, 2 parts of
iron filings fine sand
slurry, 3 parts of
water reducer, 3 parts of
retarder, 2 parts of
defoamer, 1 part of expansion agent, 20-25 parts of water; The invention provides sleeve grouting material mixed with iron filings fine sand, its preparation method and supporting strength detection method. This application uses processed iron filings fine sand to replace the aggregate in the original sleeve grouting material. Therefore, the compactness and strength of the sleeve grouting material are improved; since the iron filings are also equivalent to fibers, the
crack resistance of the sleeve grouting material is improved. Therefore, the use of iron filings can greatly improve the strength and
crack resistance of the
slurry. Since the application is mainly prepared with
pig iron filings, the cost is low, and the prepared sleeve grouting material is tested for
compressive strength to
ensure product reliability.
