- Synopsis
- Concrete containing a large amount of mineral admixture has excellent characteristics in terms of low heat generation and chloride penetration resistance, and it is advantageous for allowing the utilization of industrial by-products and low-quality aggregate. Further, it is expected to reduce the environmental impact of concrete through the use of a large amount of mineral admixture having lower unit emission of CO2 than Portland cement. Despite these promises, widespread use of such concrete remains to be achieved. Having been commissioned to consolidate the known characteristics of such concrete and issue recommendations for its use, the Concrete Committee of the Japan Society of Civil Engineers established a research subcommittee for this purpose, and in September 2018, it published "Recommendations for Design and Construction of Concrete Structures Containing High-volume Mineral Admixtures". It is hoped that these Recommendations will promote increased use of this type of concrete, and thereby lowered impact on the environment and more effective use of resources, as well as improvement of the durability of concrete structures.
