This invention aims to provide a novel material to be used for the production of components used in the construction industry such as construction blocks, wall panels, floor and roof tiles, lintels and any other product that could use this novel material. The novel material is a paper concrete made with 50% to 90% of recycled paper in the base mixture. This invention also aims to provide a novel process for making a construction block with the base mixture of paper concrete. The process for making the lightweight building blocks with this paper concrete has three main steps with two stages each. The base mixture for the paper concrete is essentially interlinked with the process for making this construction block. The two first steps of the process are crucial to achieve the base mixture and the following step is crucial to achieve a construction block. Thereafter, there are possibilities for producing these blocks with different colors by adding pigment to the paper pulp at stage 1 and adding artistic molds to the molds on the block making machine in stage 6.

To provide a practical mat for decorative aggregate exposed finishes applying for decorative finished concretes or the like and a method of industrially manufacturing a novel mat for decorative aggregate exposed finishes carrying a wide variety of decorative aggregates such as made of natural stones, ceramics, glass and plastics. A practical mat for decorative aggregate exposed finishes according to this invention is made through following steps; placing a hot melt adhesive film on one surface of soft and flexible decorative aggregate carrying net having a mesh size smaller than the particle size of decorative aggregates and greater than 2 mm, placing decorative aggregates on the hot melt adhesive film, and heating them entirely to a temperature higher than the melting point of the hot melt adhesive, thereby adhesively bonding the decorative aggregates and the carrying net for reinforcement firmly.

This invention is directed to a continuous process for producing a molded thermoplastic fiber reinforced article having a high resin concentration in at least one surface thereof. The finished article may be prepared by compression molding and can have a Class A surface. The continuous process includes coating at least one surface of a heated fiber mat core with a melted first thermoplastic resin, passing the fiber mat core into an extrusion zone wherein a melted second thermoplastic resin is extruded onto at least one surface of the fiber mat core and then molding the fiber mat core and thermoplastic resin into a finished article. The continuous process of this invention provides for fast production of molded finished articles such as roof tile, automobile exterior panels, house siding, etc.
