Mineral material for civil engineering or construction purposes such as roads, parks and traffic areas or routes, comprises basic- and additive material, where components of mineral material are milled in powder mold and are mixed together

摘要

The mineral material (1) comprises a basic- and an additive material, where the components of the mineral material are milled in a powder mold, are mixed together and are burned to a water-impermeable blanks with closed porous structure in the mixed state. The blanks are provided as material for a substructure of roads, parks and traffic areas having air gaps formed between the blank grains and are crushed to a bulk product (4) with a predetermined grain size, which is larger than the grain size of zero. The additive material is aluminum powder and/or pumice powder. The mineral material (1) comprises a basic- and an additive material, where the components of the mineral material are milled in a powder mold, are mixed together and are burned to water-impermeable blanks with closed porous structure in the mixed state. The blanks are provided as material for a substructure of roads, parks and traffic areas having air gaps formed between the blank grains and are crushed to a bulk product (4) with a predetermined grain size, which is larger than the grain size of zero. The additive material is aluminum powder and/or pumice powder. The bulk product is compressable under the formation of water-permeable intermediate spaces (5) and is loaded under maintaining a given maximum height. The mixed components of the mineral material are burned to the blanks under air supply. The basic material is basalt powder, ceramic powder, slag powder or quartz powder. The bulk product has a grain size of 11-62 mm. The bulk product is partially provided for the carrier layers of the superstructure of the roads, parks and traffic areas. The bulk product for the superstructure has a grain size of 11-32 mm. The maximum height of the bulk product for the substructure is 80 cm.
