The invention discloses an accurate matching and efficient splitting experimental device for early strength of an activated
fly ash-doped
cement test piece. The matching precision of the
fly ash and the micro-nano material is an important factor influencing the early strength of a micro-nano material activated
fly ash-doped
cement test piece, and weighing for manufacturing a
standard test piece is carried out manually and gradually; due to multiple sensitive factors of the early strength, the
standard test piece is mostly taken out from a matching cylindrical
pipe and is disassembled from the bottom or the top end by means of external force, and the test result is influenced, so that the accurate matching and efficient splitting experimental device for early strength of the test piece is needed. Different components such as micro-nano materials,
coal ash and water are distributed to the middle-layer vibration platform through 4-6 sets of precise metering filling pipes arranged on the upper-layer platform, are uniformly stirred through a stirring
system and then are lowered to the lower-layer early strength matching cylindrical
pipe on the basis of full vibration of the vibration platform; by means of layered stirring and compaction of an intelligent stirring
system and full vibration of a lower-layer vibration platform, after 6-8 hours, the early strength matching cylindrical
pipe is placed in a
strength testing device to be laterally split, and then accurate early strength matching and efficient splitting can be completed.
