ABSTRACT:
The invention relates to a material which consists essentially of sand and polymers as well as optionally, a small quantity of aggregates. The invention also relates to a method for producing this material, comprising the following steps: producing a hot molten mixture consisting of sand and polymers; introducing said molten mixture into a mould; cooling the molten mixture under pressure until the molten mixture hardens in the mould. The material can be used e.g. for producing building blocks, pavement slabs, manhole covers, housings in electrical engineering and insulators for high-voltage applications.
