Abstract
Abstract A method of manufacturing a resin concrete, where the concrete is composed of inert fillers and of thermoplastic resin. This method is characterized by the fact that the resin is used as a bonding agent and that an oxidizing additive is added to the thermoplastic resin to ensure the bonding of the resin to the fillers.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
66 words
A process for the production of a resin-based concrete which comprises mixing (i) an inert filler (ii) a thermoplastic resin selected from the group consisting of polyethylene, polyvinylchloride and polystyrene, the thermoplastic resin being present in an amount within the range of 2-12% inclusive by weight of the inert filler (iii) alumina present in an amount within the range 1-6% by weight of the thermoplastic resin.
Claim 2
Dependent Claim
66 words
A process for the production of a resin-based concrete which comprises mixing (i) an inert filler (ii) a thermoplastic resin selected from the group consisting of polyethylene, polyvinylchloride and polystyrene, the thermoplastic resin being present in an amount within the range of 2-12% inclusive by weight of the inert filler (iii) alumina present in an amount within the range 1-6% by weight of the thermoplastic resin.
Claim 3
Dependent Claim
29 words
The process claimed in claim 1, wherein the inert filler is selected from the group consisting of Limestone Porphyry Pozzolana Marble chips Expanded glass balls Expanded clay Sea sand.
Claim 4
Dependent Claim
76 words
The process for the production of a structure from resin-based concrete comprising the steps of: (i) heating 1000 kg. of limestone gravel filler to 180° C. (ii) adding to the heated gravel 49.5 kg. of particulate polyethylene and 0.5 kg. of micronized alumina (iii) whilst maintaining the whole at 180° C., mixing the constituents until homogeneous (iv) spreading and rolling the mixture whilst still hot (v) allowing the spread and rolled mixture to set by cooling.
