A filler for production of cement-bound shaped bodies, comprising a material group mixture of comminuted and sorted waste materials, conditioned with chemical reagents/compounds in the presence of water, wherein the material group mixture is composed of comminuted and sorted waste materials, selected from the following material groups: PPK: paper, paperboard, cardboard plastics inert material textiles wood
which are mixed according with a mass-related material group vector and then comminuted.

Described herein are processes for the activation of glass pozzolan as well as the activated product. Methods of using the activated product are also described.

A mixer and a mixing unit for mixing and handling industrial side-stream materials. The mixer (6) is arranged onto a movable work machine (5) and it is used for mixing at least two side-stream materials to form a geopolymer. The mixer (6) comprises: a bucket part (27) for loading and transferring the side-stream material; a mixer apparatus (26) for mixing the side-stream material which has been loaded into the space delimited by the bucket part (27); a connecting device (25) for connecting the mixer (6) to a boom of a work machine (5); and at least one measuring device (S1, S2, S3) for determining properties of the material in the mixer (6).

An arrangement and a method for mixing and handling industrial side-stream materials. The mixer (6) is arranged onto a movable work machine (5) and it is used for mixing at least two side-stream materials to form a geopolymer. The side-stream materials are processed between a waste pile (4) and a casting area (13) in the mixer (6). Cast paste is allowed to harden and after that it is crushed to obtain an earthwork material.

Trona-accelerated composition for backfilling trenches are described. The compositions consist of aggregate (e.g., sand), Portland cement, Trona, water and sometimes air. The compositions may have a compressive strength of between 10 psi and 100 psi after 4 hours, a compressive strength of between 75 psi and 500 psi after 28 days, and a penetration resistance of between 4.5 tsf and 200 tsf after 4 hours. Also disclosed are methods of filling a trench with fast-setting flowable fill.
