Production process

1.   Prestressed concrete pillar&column producing bed prepare and tensioning.

1.1  Cleaning the producing bed：Cleanthe concrete residue on the producing bed with special tools and make the platform surface clean, smooth.

1.2  Painting parting agent：The adopted parting agent must be up to the required standard without harmful
chemical substance.

1.3  Distribute the steel wire.Steel wire of low relaxationand stress relieving is adopted .

2.  Precast concrete pillar&column material compositions and quality standard 

1.1 Cement：32.5R or 42.5R Portland cement and ordinary Portland cement

1.2  Sand：Medium sand

1.3 Stone：Rubble and broken pebble are optional

1.4  Water：Drinking water without harmful substance

1.5  Dry concrete is used for precast concrete pillar&column with a strength grade of C30 or C40.

3. Prestress concrete pillar&column technological flow

Cleaning the producing bed→ painting parting agent→ distribute steel wire and fix→tensioning the steel wire→ mix and transportation of concrete → slab molding →make testing block→ covering and curing →testing block intensity →relief the steel wire→ cutting slab→ storage
