Concrete admixtures and accelerators designed for shotcrete
Concrete accelerators designed for shotcrete applications Concrete accelerator admixture Set accelerating admixtures are best defined as those which, when added to concrete, mortar or paste, increase the rate of hydration of hycraulic cement, shorten the time of setting and increase the rate of early strength development.
Accelerating admixtures for shotcrete
Non-alkaline powder accelerators The non-alkaline powder accelerators were first used in shotcrete at the beginning of the 1990s.8 Generally, these are calcium aluminate-based admixtures used in dosages from 6 to 12%.
Wet sprayed concrete and admixture for concrete
Wet sprayed concrete and admixture for concrete Wet shotcrete is a mixture of aggregate (gravel and sand), cement, water and advanced admixture. Transferred through a hose to the nozzle, Compressed air and shotcrete accelerators are introduced at the nozzle to impel the mixture onto the receiving surface.
Shotcrete Solutions | Sika Indonesia P.T.
SikaTard®-930 is mainly used in wet and dry spray shotcrete where cement hydration of the concrete mix is prevented until it is required. It is therefore possible to stabilise mixed concrete for hours or even days i.e. in tunnelling work. Characteristics and Advantages. SikaTard®-930 blocks cement hydration.
Sprayed Concrete Admixtures and the Process - Online CivilForum
Sprayed Concrete Admixtures and the Process. Sprayed concrete or Shotcrete is pumped to the point of application projected in high velocity used for rabid construction.The applications are frequently vertical or overhead and this requires rapid stiffening if slumping or loss by concrete detaching from the substrate under its own weight is to be avoided.
