New ASTM Standard Will Help Improve Concrete Production

A new ASTM International standard will help with efforts to enhance the cement content in concrete while also reducing CO2 emissions during production.

The new specification (C1797, Specification for Ground Calcium Carbonate and Aggregate Mineral Fillers for Use in Hydraulic Cement Concrete) was developed by ASTM International’s committee on concrete and concrete aggregates (C09).

The new standard covers the use of ground calcium carbonate and aggregate mineral fillers used in concrete.

According to ASTM member Caroline Talbot, “Limestone and fillers can help optimize concrete mix design in terms of workability and finishing by improving packing density. Notably, this will reduce the amount of cementitious product needed for concrete production, making it a more environmentally friendly alternative.”

Better packing density improves both plastic and hardened properties, including shrinkage, according to Talbot, who serves as national technical service manager for Euclid Chemical. In addition, there are indications that the presence of ground limestone enhances the hydration of cement and flyash.

The new standard will be useful to anyone who produces, or otherwise works with, concretes, as well as other materials. Materials covered by the standard have been used around the world for years; C1797 will allow these companies to show that their materials can be used in concrete without negatively affecting fresh or hardened properties, leading to cost savings and environmental sustainability.
