Concrete Mix and Placement. The strength of the concrete has a lot to do with the mix and application. Shotcrete or Gunite, does not matter so much. More importantly is the water to concrete ratio, or hydration. Too much water can weaken concrete, but too dry and it becomes hard to work with and shape into a pool.
Wet mix shotcrete process. Dry mix shotcrete machine is very suitable for slope-protection, compared with wet shotcrete machine, dry mix shotcrete machine lower construction costs, only need extra air compressor and water pump. Air compressor is mainly used for providing need compressed air, while water pump is used for provide water on the nozzle.

For many years slope protection of dams has been designed empirically, with satisfactory results in most cases (Johnston, 1999). A conventional rule used by many engineers required the depth of riprap or concrete blockwork on dams in the UK to be not less than one sixth of the ‘significant’ wave height in the design event.

Shotcrete is perhaps the most diverse method available for concrete construction.
In the dry-mix process, there is a wide range of control over the amount of mixing water used to adjust mix consistency as the job progresses. It also allows transportation of the mix through a longer length of hose than is possible with wet-mix. The dry-mix process is better suited for concrete containing lightweight porous aggregates than it is for a mixture with normal weight aggregate.

Malibu uses concrete as 'erosion' control. Weird! The coastal sage scrub is beautiful and stable. Some dummy clears the 'brush' and plants grass, the hillside slides, so they cover it with cement that gradually cracks, costs a fortune, looks UGLY, and is dead. And after about twenty years, the concrete falls off of the slope.
