◀️ It is not recommended to use a mixer truck for the following concretes: Concrete with slump less than 40 mm Concrete with a maximum aggregate size of more than 50 mm Concrete with a water-cement ratio of less than 0.4 (without the use of lubricant or super-lubricant additives) In the dry measuring method, microsilica should not be used in powder form, because the distribution of microsilica particles in the mixture is not uniform.

◀️ If the mixer truck is used for primary mixing (dry measure), the volume of concrete made in it should be limited to two thirds of the nominal capacity of the boiler. For example, with a mixer truck with a nominal capacity of 6 cubic meters, it is possible to mix 4 cubic meters of concrete using the dry cube method.
