Accelerator action mechanism experimental method based on concrete hardening strength and morphology

The invention discloses an accelerator action mechanism experimental method based on concrete hardening strength and morphology. The accelerator action mechanism experimental method comprises the following steps: selecting a cementing material and an additive for preparing concrete; respectively proportioning according to the selected cementing materials and additives to obtain three groups of cement paste, and respectively testing the paste setting time according to the three groups of cement paste; respectively proportioning according to the selected cementitious materials and additives to obtain three groups of cement paste, and respectively testing the mechanical properties of the paste according to the three groups of cement paste; and carrying out microscopic morphology observation on the three groups of cement neat pastes after neat paste mechanical property testing. The technical problem that in the prior art, when an accelerator is used for promoting rapid setting and hardening of sprayed concrete, t
