Abstract

The continuous two stage mixing process prepares concrete for forceful projection by lance (7) onto plane or inclined surfaces e.g. in the making good of structures by applying a relatively thin reinforced skin. The process entails the separate mixing of the binder before introducing it to the aggregates. The binder is mixed with a quantity of water in a prim. mixing chamber (8). The mix is then forced (12) under pressure along a feed pipe (10) and into a sec. mixing chamber (1). The latter receives a flow of dry aggregates (14) through a sec. pressurised feed pipe (15).
