Abstract
A filler for production of cement-bound shaped bodies, comprising a material group mixture of comminuted and sorted waste materials, conditioned with chemical reagents/compounds in the presence of water, wherein the material group mixture is composed of comminuted and sorted waste materials, selected from the following material groups: PPK: paper, paperboard, cardboard plastics inert material textiles wood which are mixed according with a mass-related material group vector and then comminuted.
Claims21
A filler for the production of cement-bound mouldings, comprising a dry and crushed material group mixture of comminuted and sorted residual materials, wherein the comminuted and sorted material of the dry and crushed material group mixture is present in proportions of 20% by mass PPK comprising paper, cardboard, cardboard packaging, 40% by mass plastics, 20% by mass inert materials comprising glass, ceramic, porcelain, stone and earthenware, 15% by mass textiles, and 5% by mass wood.
A moulded article made from the comprising a filler comprising a dry and crushed material group mixture of comminuted and sorted residual materials, wherein the comminuted and sorted material of the dry and crushed material group mixture is present in proportions of 20% by mass PPK comprising paper, cardboard, cardboard packaging, 40% by mass plastics, 20% by mass inert materials comprising glass, ceramic, porcelain, stone and earthenware, 15% by mass textiles, and 5% by mass wood, which is processed with cement and water to form the cement-bonded moulding.
A method for the production of a filler comprising a dry and crushed material group mixture of comminuted and sorted residual materials, wherein the comminuted and sorted material of the dry and crushed material group mixture is present in proportions of 20% by mass PPK comprising paper, cardboard, cardboard packaging, 40% by mass plastics, 20% by mass inert materials comprising glass, ceramic, porcelain, stone and earthenware, 15% by mass textiles, and 5% by mass wood, comprising the steps:
- homogenisation of the material group materials in a mixer;
- comminution of the material group materials and homogenisation of the comminuted material mixture;
- addition of chemical reagents aluminium sulphate, calcium oxide or calcium hydroxide and water;
- and
- storage of the mixture for a defined reaction time of 1 to 3 days.
A method of manufacturing a moulded article comprising the steps of:
- providing a filler comprising a dry and crushed material group mixture of comminuted and sorted residual materials, wherein the comminuted and sorted material of the dry and crushed material group mixture is present in proportions of 20% by mass PPK comprising paper, cardboard, cardboard packaging, 40% by mass plastics, 20% by mass inert materials comprising glass, ceramic, porcelain, stone and earthenware, 15% by mass textiles, and 5% by mass wood
- mixing the filler with cement and water and incorporating the composition into mould or form to produce the moulded article;
- setting the moulded article and removing the mould or shuttering;
- curing the moulded article for a defined number of days.
