FINAL FORM
PRECAST
Ohio ready mixed, aggregate, concrete masonry and precast
producer R.W. Sidley Inc. recently developed a lean, aesthet-
ic alternative to armor-type block synonymous with returned
concrete mixes and aggregate stockpile containment.
Subsidiary Carr Concrete Corp., Williamstown, W.V.,
engineered and fabricated precast concrete push walls
to frame aggregate storage bins, including those for Si-
dley-branded Pro/Angle Angular Bunker Sand and other
custom blended grades. Bins at the producer's Thompson,
Ohio, operation store up to 2,000 tons of sand each; help
to prevent contamination of the product from the ground
or wind; and, afford a more accessible loading area for
trucks than alternate structures. Carr Concrete crews post
tensioned the push wall members to impart greater stabil-
ity and strength for the Pro/Angle bins.
Carr Concrete details the push walls as freestanding
precast structures that can be used for barriers, erosion
control, and drainage outlets, in addition to sand & gravel
or crushed stone containment. The standard section is 14
ft. long, 7.5 ft. high and has a 2 ft. 8 in. base tapering to
4.75 inches at the top. Standard push walls are cast with
4,000 psi concrete and reinforced with conventional bar
or wire mesh per engineering conditions. Members can be
made with weld plates, PVC conduit or other connection
means if a project requires.
