A modularly constructed, trailerable, skid mounted, multi-compartmented concrete mixer and cement storage silo having a plurality of longitudinally aligned, bottom mounted, driven feed chains. In a combination construction, a single motor is cooperatively coupled to the feed chains of each mixer compartment and the feed chain of the cement silo to feed the cement/sand/aggregate in metered quantities to a turreted, separately powered auger where water is added and along the length of which the concrete is mixed. A silo vent column includes a plurality of fabric collection filters and means for vibrationally removing and reclaiming the cement. Air infiltration ports mounted along the bottom of the cement silo and one or more vibrators mounted to the mixer adjacent the sand and aggregate bins prevents crusting. Alternatively, the silo may be self-powered, and/or the mixer and silo may be transported independent of one another and/or without the trailer.
