TL・PC girder (The high-strength,Lightweight and high-durable prestressed concrete girder using high-strength fly ash artificial aggregate)
Characteristic & Merit This high-strength artificial lightweight aggregate made of the coal ash produced from thermal power plant to be raw material. Therefore ,this aggregate greatly contributes to recycling of resources.

The following thing is shown as the characteristics of the TL・PC girder.

1.High-strength (Concrete strength:over 1000N/mm2)
2.Lightweight (Concrete density:2.0ton/m3)
3.High-durability (Freeze-thaw resistance,salinity penetration resistance is high)
4.Construction improved (good flowability,girder is light)

The repression of height of girder and the reduction of the girder mass can be attempted in comparison with the traditional PC girder, and they are several % cost reductions of the bridge beam superstructure work.
It becomes a bigger cost reduction when effect on a superstructure work dead load decrease is made to spread even to the substructure work.
