The Cement and Concrete Section is divided into three areas: Concrete Lab, Cement Lab, and On-site Plant Inspection.
Capabilities of the Concrete Lab are:
· Compression testing of concrete, cylinders, cores, brick & block
· Flexural strength of concrete beams
· NDT for concrete strength
· Air content of hardened concrete specimens
· Freeze-Thaw testing
· Curing-compound testing
· Beam breaker & equipment calibrations
· Rapid Permeability Testing
· Inter-lab testing of concrete items
The Cement Lab tests:
· Cement,
· Fly Ash,
· GGBF Slag
· Micro Silica
· Patching materials
· Chloride content
Plant inspections are performed assure the quality of the following manufactured concrete items:
· Prestressed concrete beams in accordance with ODOT 515 & Supplement 1079
· Certified Precast Concrete Producers in accordance with Supplement 1073 in the production of; three and four sided box culverts, precast manholes, catch basin/inlets, precast barrier, precast headwalls and other miscellaneous precast concrete items
· Certified Concrete Pipe Producers in accordance with Supplement 1074 in the production of circular and elliptical concrete, culvert, storm drain and sewer pipe
