Recycling of old road material contg. tar - involves disintegration of material for mixing with binder for making concrete blocks

摘要

The fraction sof the granulate from 0 to 3 mm are sieved out, and are pressed to form briquettes for storage during a period of 28 days. After storage, the briquettes are broken and the resulting granulate is sieved, whereby the granular fractions over 3 mm are processed to make concrete blocks and the fractions under 3 mm are made into briquettes. The sieved-out granular fractions under 3 mm are mixed with a binder medium and then pressed. USE/ADVANTAGE - To recycle old road material, to make concrete bocks and briquettes.
