| Description: | Miscellaneous Paper Abstract: This report documents the preliminary investigation of a newly developed cementitious material from Ash Bonding Chemicals (ABC) Corporation. The ABC cementitious material is a new, high-early strength, blended-hydraulic cement composed primarily of subbituminous Class C fly ash. The Class C fly ash generally makes up 77 to 95 percent by weight of the total material. The remaining part can be slag and/or portland cement. Four readily available chemical compounds were used in small quantities to control the workability and setting time of the cementitious material, to enhance the strength, and to improve the durability. These admixtures are a set-suspending agent, an activator, a modifying retarder, and an accelerator. The objective of this research was to conduct a preliminary investigation of the ABC cementitious material to determine its viability for use in producing workable, durable, high-early strength concrete. Two ABC cements were used in the investigation, each being produced from a different source of Class C fly ash. Concrete mixtures produced with Type III portland cement, including a water-reducing admixture and a high-range water-reducing admixture, were tested for a comparison. The results indicated the ABC cementitious material as a possible alternative to Type m portland cement for producing high-early strength concrete. |
