Samenvatting
Performance concrete is developed by optimizing concrete mix designs to more easily produce concrete that meets all structural and performance requirements of a project using the most cost-effective materials. Two projects with severe performance requirements are described, to show the importance and utility of this process. Selectionof the basic mix ingredients as a function of the ultimate demands of a project is discussed. Developing performance concrete is concluded to be the most cost-effective way to approach a project, and optimization must be an integral part of the development process.
