A machine for combining powder material with cohesive site-won spoil has an input hopper (4) which provides a preliminary breaking up step. Some lime is added from a lime feeder (6) as the material is transported to a pan mixer (8). During transport a rotavator (30) acts on the cohesive material so that finely divided material enters the mixing means (8). Further powder ingredients can be added to the components in the pan mixer (8) by means of a powder ingredient supply system (10).
