Abstract
The Illinois Department of Transportation (IDOT) is making several changes to concrete mix designs, using revisions to cement specification ASTM C150/AASHTO M85 and ASTM C465/AASHTO M327. These proposed revisions will enable the use of more sustainable materials for concrete pavements, overlays, and bridge decks. Accordingly, a study was conducted by the University of Illinois at Chicago (UIC) to test the performance of concrete mixes batched with cement comprising less (conventional) and more (modified) than 5% by weight of limestone and inorganic processing additions (IPA) specified in ASTM C465/AASHTO M327, and/or insoluble residue (IR) with quantity above the specified limit by ASTM C150. Twenty-four concrete mixes with different cementitious combinations and aggregates were developed for this study. Each cement source was batched in a concrete mixture by replacing 30% of the total cement content with supplementary cementitious materials (SCMs), fly ash, or slag. Also, each cementitious combination was batched with fine aggregates (either natural or combined sand) and coarse aggregate (crushed limestone). The study included measuring fresh properties such as the slump, air content, unit weight, and setting time. The hardened properties included measuring the strength and durability for each concrete mix combination. The strength results were measured in terms of compressive and flexural strength, and the durability results were measured in terms of rapid chloride penetration resistance (coulombs), water permeability (DIN 1048), chloride ion penetration, and freeze/thaw tests of the concrete mixes. The study found similar performance in terms of strength and durability of concrete between the conventional and modified cements and demonstrated their performance with SCMs replacements and fine aggregate types.
