· (1) Bond strengths of new shotcrete to existing materials are generally higher with dry-mix shotcrete than with wet-mix shotcrete. Both shotcrete mixtures often provide significantly higher bond strengths to existing materials than does conventional concrete. (2) Typically dry-mix shotcrete is applied at a much slower rate than wet-mix shotcrete.

· In wet-mix shotcrete a mixture of cement aggregates and water is transported by a pump where air pressure is applied to project the materials to the surface. When the dry-mix shotcrete is specified a mixture of pre-dampened aggregates and cement is conveyed by a hose to a nozzle where water is added and then projected at high velocity onto

The Monolithic EHP 1500. The Monolithic EHP 1500 Peristaltic Carrousel Pump is an excellent small line electric hydraulic shotcrete pump for stuccos and concrete. It is made from the toughest materials available at an affordable price. The unit is designed for maximum capacity and minimum maintenance.
What is shotcrete and when is it used
Shotcrete is applied using a wet- or dry-mix process. The wet-mix shotcrete process mixes all ingredients including water before introduction into the delivery hose. The dry-mix shotcrete process adds water to the mix at the nozzle. Shotcrete is used in new construction and repairs and is suitable for curved and thin elements (ACI 506R).

The Trouble With Silicon Carbide Pumps Systems
· Traditionally pump manufacturers used SiC (silicon carbide) for bushings and bearings in these pumps because of its high hardness and ability to withstand abrasive wear in solid media. Since the early 1980s OEM pump manufacturers have been using sintered SiC bearings for the stationary and rotating components of tubular casing pumps.
