Compact a 100 mm × 100 mm × 200 mm test piece in a 100 mm × 100 mm × 400 mm mid-beam test mold, demold, then standard curing for 7 days, and then put back into the test mold. The cement slurry was applied on the top of the test piece, and then the mold was filled to prepare the 100 mm × 100 mm × 400 mm test piece, and then the whole test piece was demolded, taking the standard curing for 90 days.	Compact a 100 mm × 100 mm × 200 mm test piece in a 100 mm × 100 mm × 400 mm mid-beam test mold, and then fill the mold with the mixture to prepare a 100 mm × 100 mm × 400 mm test piece, demold, and then standard curing for 90 days.
