For household and personal use for small concrete jobs, drum, mortar and vertical shaft mixers offer their own set of benefits. Most of these machines are available with either gas or electric-powered motors, and they all come in a large assortment of sizes to meet various needs.

Drum mixers are a common style of mixerthat typically has fixed fins that are attached inside of the drum that mix the concrete and water as the drum rotates.
