Fishers, Ind.-based Builder's Concrete & Supply is the premier user of a portable roller compacted concrete mixer designed by Sicoma Strength and Stephens Mfg. Built around a horizontal twin shaft mixer, widely used in RCC dam construction, the 35-ft.-long unit affords the flexibility of producing the material at one of Builder's three satellite transit mixed plants.
Bearing on a tandem axle and 17.75-in. frame rail, the Sicoma MAO 6000 mixer has a charge height just over 13 ft. It feeds a bend-up conveyor with 42-in.-wide x 50-ft.-long belt. At a 20-deg. angle, the conveyor provides a 12-ft. clearance for dump trucks, transferring mixes through a .75-yd. hopper and 48-in. double clamshell gate. The mixer's 6-yd. capacity equates to a two-batch cycle for projects served by conventional dumps.
Builder's Concrete is among Indiana ready mixed producers promoting RCC as an alternative to asphalt for base layers or full-depth pavements in light- and heavy-duty parking, shoulders, truck service applications, municipal streets, and scrap yards. After delivering RCC orders for Indianapolis, Brownsburg, Carmel, and Fishers street projects, and hearing transportation agenciesÌ concerns over asphalt pricing volatility, the producer is ramping up RCC capabilities with the Sicoma/Stephens equipment.
