Definitions
- the invention relates to a method for delivering a premixed lightweight concrete mass to an installation location according to the preamble of claim 1.
- the aim of the invention is to avoid this disadvantage and to propose a method of the type mentioned at the outset in which the concrete mixture can be transported in a simple manner, with the transport being able to be carried out without great mechanical outlay.
- the proposed measures ensure that the finished concrete mix is ready for installation. e.g. mixed earth-moist, divided into relatively small volumes, whereby segregation is largely prevented even if the mixture is exposed to vibrations during transport.
- the sacks provided according to the invention can be filled and loaded very easily and unloaded again at the installation site, and the filled sacks can also be transported on open platform trucks.
- the premixed masses retarders can be added.
- the premixed concrete mass can be kept in a ready-to-install state for a long time, so that a correspondingly long time is available for the transport of the masses.
- the pre-mixed mass can be kept processable for a period of four to six hours.
- Such concrete mixtures can also be transported over long distances by the process according to the invention without the mixed mass ready for installation being separated. A loss of moisture in the mixture is also prevented by using bags made of plastic.
- the bags can be easily loaded or unloaded by hand, so that there is no need for complex mechanical hoists.
- the bags can have a filling volume of 100 to 150 liters. The proposed measures make it possible to keep the use of machines and energy low and also to reduce the use of specialist personnel to a minimum.
