Waste tires used in self-compacting concrete. Oil industry waste used as a partial replacement of cement. Ground granulated blast furnace slag used in place of natural coarse aggregates. These concepts are just a few examples of current research into sustainable technologies in the concrete industry, available through ACI’s Materials Journal Recently published research papers in ACI’s Materials Journal highlight the concrete industry’s efforts in sustainability. Long recognized as one of the foremost worldwide resources, the journal continues the publishing tradition the Institute started in 1904. The September/October issue of the journal includes a number of sustainability-related papers that highlight ACI’s commitment to facilitating and communicating the sustainable and environmental benefits of concrete Laboratory Investigation of Self-Compacting Waste Tire Rubberized Concrete Economic development characterized by excessive industrialization has led to a significant increase in solid waste, particularly scrap tires. These programs encouraged civil engineering researchers to recycle waste rubber by utilizing it as a construction material. This paper focuses on a detailed laboratory investigation of waste tire rubberized self-compacting concrete carried out in two phases. Download preview. Mechanical Performance of Concrete Added with Waste from Oil Industry This paper evaluates the mechanical properties of concrete added (10, 20, 30%) with a residue of the petrochemical industry, called catalytic cracking catalyst residue. The incorporation of this residue in concrete in percentages below 30%, has both technical and environmental benefits, besides reusing a waste product, partial replacement of cement in concrete is possible, thus reducing the environmental impact of its production. Download preview. Combined Use of Natural and Artificial Slag Aggregates in Producing Self Compacting Concrete This study addresses properties of self-compacting concretes in which natural coarse aggregates had been substituted by artificial slag aggregates. Since aggregates are the main volumetric component of concretes occupying 65% to 75% of total concrete volume, producing artificial aggregates to be used in making concrete may be considered as an effective way to recycle such mineral admixtures. Moreover, the natural and/or scarce materials of aggregates may be conserved and damaging activities of aggregate mining may be prevented as the artificial aggregates replace the natural ones, especially in self-compacting concretes. Download preview. Strength and Durability of Composite Concretes with Municipal Wastes This paper investigates the influence of different types of polyethylene substitutions as partial aggregate replacement of micro-steel fiber reinforced self-consolidating concrete incorporating incinerator fly ash. The study focuses on the workability and hardened properties including mechanical, permeability properties, sulfate resistance and microstructure. Download preview. ACI will continue to champion development of scientifically-backed consensus technical resources, advocate for integration of resilience into sustainability activities, and partner with leading authorities. Earlier this year ACI enhanced both the ACI Materials Journal and the ACI Structural Journal – with expanded content and greater digital accessibility. Learn more. Subscribe to the Journals.
