Can the Pump Handle Your Concrete Mix?
Many decorative concrete contractors have preferred no-fail concrete mixes they rely on for the majority of their projects. If you have your own gold-standard mix designs, you'll need a pump built to handle them. Some pumps are multipurpose machines that can accommodate a variety of mixes while others are engineered for specific mix types. Generally, the maximum aggregate size the pump can accept will govern the type of material it can churn out efficiently. Pea-rock pumps, for example, are designed to pump cement-based mixtures containing a 1/2-inch top aggregate size, such as repair grouts, shotcrete, and self-leveling overlays. Other line pumps can handle higher-slump concretes containing larger coarse aggregate (3/4- to 1 1/2-inch rock). These models are better suited for placing concrete slabs and other structural elements.
