Abstract
There is disclosed an apparatus for supplying a dry mortar mix comprising containers with a gate valve at one end and a hook at the opposite end and a support for holding at least two such containers with the gate valve lowermost and the hook uppermost. The support is placed at a construction site and the containers are filled at a plant with dry sand and cement mortar mix and are delivered to the construction site by truck. Installation of the containers and the support is done by a crane. Empty container(s) are removed and replaced by full one(s). Other container(s) can be tapped in the meantime to ensure that the supply of mix is continuous.
