Abstract
Through the use of crushed foam glass derived from old glass or blast-furnace slag by way of aggregate for a casting compound which is bound with a binder, a building material was obtained that enables very wide-ranging applications.
Claims46
A light weight aggregate for a casting compound that is bonded with a binder, comprising:
- a plurality of foam glass lumps of crushed foam glass, the foam glass lumps exhibiting a screen-analysis curve that is graded between 0 and a largest grain size with at least 3 fractions.
A method to produce a casting compound comprising the steps of:
- providing a light weight aggregate;
- and
- binding the light weight aggregate with a binder,
- wherein the light weight aggregate comprises a plurality of foam glass lumps of crushed foam glass, the foam glass lumps exhibiting a screen-analysis curve that is graded between 0 and a largest grain size with at least 3 fractions.
1 more element
A flowable and settable casting compound, comprising:
- a binder;
- and
- a light weight aggregate comprising a crushed foam glass,
- wherein the crushed foam glass exhibits a screen-analysis curve that is graded between 0 and a largest grain size with at least 3 fractions.
1 more element
A structural member formed from a casting compound comprising:
- a binder;
- and
- a plurality of foam glass lumps of crushed foam glass, the foam glass lumps exhibiting a screen-analysis curve that is graded between 0 and a largest grain size with at least 3 fractions,
- wherein the structural member is cast in situ as a prefabricated element.
1 more element
A process for producing a structured surface in a cast structural member, the process comprising the steps of:
- pouring into a formwork or mold a casting compound, the casting compound having a binder and a plurality of crushed foam-glass lumps by way of aggregate;
- setting of the casting compound;
- and
- eroding a surface of the casting compound.
