Low pressure steam is one of the most spread fluids used for accelerated concrete curing processes.

From a practical point of view the manufactured products are loaded in curing chambers or tunnel or fresh concrete is poured in moulds, which needs to be covered with suitable tarpaulins to retain steam and ensure an ideal curing atmosphere.

Direct steam injection (live steam) ensures both temperature increase and addition of moisture. These combined effects promote the attainment of high strength values in short times.

Ione manufactures low pressure steam boilers even available in mobile arrangement and container package.
