Energy Conservation in the Building Industry Using Industrial Waste Materials - Phase I

摘要

The primary objective of the study was to utilize Californian waste fly ash, pozzolan, and other regional waste materials and to conduct a feasibility study to develop potential building products. The scope of the study included the physical, chemical, and mineralogical characterization of the fly ash and waste cement, and processing and characterization of the materials. Techniques were used involving the fabrication of test samples using a hydraulic press and development of a curing procedure to form a cement bond. Samples were tested using the pozzolanic index and freeze-thaw tests to determine their essential properties including compressive strength, and to identify mineralogical phases (cementatious bonds). Without the use of any energy compressive strength of over 2000, PSi were achieved. The pozzolanic index test was better than the ASTM requirements and the samples withstood a 25 cycle freeze-thaw test.
