Embodiment 1
[0032] A. Detect and adjust the particle size of recycled rubber powder to meet the following requirements:
[0033] 40 mesh 10%
[0034] 60 mesh 10%
[0035] 80 mesh 25%
[0036] 100 mesh 25%
[0037] More than 120 mesh 30%
[0038] All the above are percentages by mass.
[0039] B. Soak the sawdust with antiseptic oil for later use.
[0040] C, first put the above-mentioned recycled rubber powder, sawdust and hydraulic cementitious material for standby use in a high-speed mixer according to the mass percentage of recycled rubber powder 15%, sawdust 24%, and hydraulic cementitious material 27%. After 3 minutes, add 33% water and 1% additive by mass, and then mix for 2 minutes to make building formwork support keel imitation wood filling slurry. Among them, high-strength Portland cement is selected as the hydraulic cementitious material; polyvinyl formal is selected as the additive.

[0042] A. Detect and adjust the particle size of recycled rubber powder to meet the following requirements:
[0043] 59 mesh 20%
[0044] 79 mesh 20%
[0045] 99 mesh 20%
[0046] 119 mesh 20%
[0047] More than 120 mesh 20%
[0048] All the above are percentages by mass.
[0049] B. The crushed platycodon grandiflorum of the agricultural crop is soaked with coal tar and then set aside.
[0050] C, first put the above-mentioned treated standby recycled rubber powder, sawdust and hydraulic cementitious material in a high-speed mixer according to the mass percentage of recycled rubber powder 20%, sawdust 28%, and hydraulic cementitious material 21%. After 3 minutes, add 30% water and 1% additive by mass, and mix for another 2 minutes to make building formwork support keel imitation wood filling slurry. Among them, high-strength Portland cement is selected as the hydraulic cementitious material; polyvinyl formal is selected as the additive.
Embodiment 3
[0052] A. Detect and adjust the particle size of recycled rubber powder to meet the following requirements:

[0054] 65 mesh 15%
[0055] 85 mesh 20%
[0056] 110 mesh 20%
[0057] More than 120 mesh 30%
[0058] All the above are percentages by mass.
[0059] B. Soak the sawdust with anthracene oil for later use.
[0060] C, first put the above-mentioned regenerated rubber powder, sawdust and hydraulic cementitious material for standby use in a high-speed mixer according to the mass percentage of 18% of recycled rubber powder, 25% of sawdust, and 24% of hydraulic cementitious material After 3 minutes, add 32% water and 1% additive by mass, and mix for another 3 minutes to make building formwork support keel imitation wood filling slurry. Among them, high-strength Portland cement is selected as the hydraulic cementitious material; polyvinyl formal is selected as the additive.
