Embodiment 1
[0023] S101: cutting the EPS material every 500mm.
[0024] To prepare anti-cracking mortar, mix 400 parts of 42.5R ordinary Portland cement, 700 parts of river sand, 8 parts of industrial gelatin, 3 parts of wood fiber, 0.5 parts of German BASF superplasticizer (model F10), 1.5 parts of methyl hydroxypropyl cellulose, 10 parts of redispersible latex powder. The mass ratio of Deutsche Mark 5010, 8031H and 5044 in the redispersible latex powder is 3:1:6.
[0025] S102: Add water with a mass ratio of 0.4 to cement, and stir evenly.
[0026] S103: Making a grid cloth, arranging alkali-resistant glass fibers vertically and horizontally on the EPS material to make a grid cloth with a grid spacing of 10 mm.
[0027] S104: forming by machine, pouring cement mortar on the grid cloth, the pouring thickness is 5mm.
[0028] S105: Natural conservation, after 42 days of natural conservation, inspection and storage.
Embodiment 2
