Abstract
A process and apparatus for producing light weight concrete including a binding agent, an inorganic aggregate and foamed plastic material, whereby the granulated plastic material is supplied to the concrete mixer via a metering mechanism. In a transfer container which is arranged in the supply system for the granulated material, the granulated material is put under a pressure higher than the pressure in the mixer in order to guarantee an exact introduction of the granulated material into the mixer.
Claims13
In a process for the production of light weight concrete from materials including a binding agent, an inorganic aggregate and a foamed plastic material, wherein a predetermined quantity of granulated plastic material is metered from a reservoir, through a supply means into a concrete mixer operating at a pressure above atmospheric pressure, the improvement comprising:
- subjecting the metered quantity of granulated plastic material, while in said supply means, to a pressure higher than the pressure in said mixer;
- and
- then transferring said granulated plastic material from said supply means to said mixer and foaming said plastic material in said mixer.
In a device for producing light weight concrete from materials including a binding agent, an inorganic aggregate, and a foamed plastic material, said device being of the type including a concrete mixer operating at a pressure above atmospheric pressure, a reservoir for metering a predetermined quantity of granulated plastic material, and supply means for supplying the metered granulated plastic material to said mixer;
- the improvement wherein:
- said supply means includes means for raising the pressure of said metered granulated plastic material to a pressure higher than the pressure in said mixer;
- and means for transferring the thus raised-pressure metered granulated plastic material into said mixer whereat said plastic material is foamed.
