Process of manufacturing of sprayable concrete and morton by using an additive

摘要

Additives for air-placed concrete or mortar, which contain a silica sol or consists thereof, lead to a marked decrease in dust evolution and recoil in the processing of the air-placed concrete or mortar by the dry or wet process. When processing the air-placed concrete or mortar, this additive is preferably added during spraying, for example in the spray nozzle.
