Properties of Chemically Combusted Calcium Carbide

Calcium carbide residue (CCR) is a waste by-product from acetylene gas production. The main component of CCR is Ca(OH)2, which can react with siliceous materials through pozzolanic reactions, resulting in a product similar to those obtained from the cement hydration process. Thus, it is possible to use CCR as a substitute for Portland cement in concrete.

Manufacturing Routes for Metallic Foams

Figure 1 provides an overview of the methods available for making metal foams. 1 One distinguishing factor is whether molten metal or metal powder is used (although the actual foaming always takes place in the liquid state). A second difference is the gas source used for creating porosity: an external source can be used, a blowing agent can be decomposed in-situ, or dissolved gas can be forced
