History

Aggregate & Concrete Testing Services Ltd. (AGGCON) was founded in 2002 to provide construction materials testing services for the construction industry. Our primary focus is to provide contractors and aggregate producers who deal with the Ohio Department of Transportation (ODOT) with an independent, accredited materials laboratory as required in a variety of ODOT contracts.

ODOT Supplemental Specification 898: QC/QA Concrete for Structures

Bridge building contractors who work under ODOT Supplemental Specification 898 are required to use the services of a "certified laboratory" (see 898.02) to test raw materials and produce a concrete mix design which meets the requirements of S.S. 898. The certified laboratory\'s mix design is approved by an ODOT engineer before being incorporated into any work (see 898.07). The certified laboratory also tests the plastic concrete as it is placed in the structure as part of the contractor\'s quality control (QC) and acceptance testing. As a check, ODOT also tests the plastic concrete, although at a reduced frequency (898.11). Finally, the certified laboratory tests the hardened concrete for acceptance and final payment (compressive strength and permeability - 898.15) with ODOT also performing some companion testing for quality assurance (898.11).

ODOT Supplemental Specification 1069: Pre-Qualified Aggregate Supplier Program

AGGCON\'s business with aggregate suppliers consists of conducting regular sieve analysis testing to comply with ODOT Supplemental Specification 1069. This testing may be conducted by the aggregate producer or contracted out to an accredited laboratory. AGGCON currently has approximately 12 aggregate producers who have elected to have us do their quality control testing.
