Abstract

A room temperature setting carbonaceous cement comprising a solid carbonaceous material, a catalyst, a liquid carbonizable component, and copper particles, which when treated with the catalyst will provide a carbon yield of at least 40% for the liquid component at an elevated baking temperature and possess increased flexural strength at elevated temperatures and reduced electrical resistance.
