• Abstract:
  Current management practice, existing regulations, and environmental consequences of municipal solid ; waste incineration (MSWI) ash utilization were comprehensively reviewed worldwide and nationwide ; in the U.S. Efforts were made to physically and chemically characterize different types of MSWI ash ; and also to evaluate their influence on engineering properties of cement paste and concrete when part of ; Portland cement (PC) and fine aggregate are replaced with ground and sieved MSWI ash. Fundamental ; properties of MSWI bottom ash and fly ash were studied by conducting physical, microstructural, and ; chemical tests. Cement paste and concrete cylinders were cast with various amounts of ash additions ; and their strength and durability were investigated as the replacement ratio of ash increases. ; The MSWI bottom ash was also used to replace fine aggregate in hot-mix asphalt (HMA). Varying ; proportions of bottom ash and fine aggregate were tried in an effort to determine the optimum ratio of ; bottom ash to fine aggregate, as determined by performance tests such as the Marshall stability test and ; the moisture susceptibility test. For the optimum replacement ratio of bottom ash, the optimum binder ; content required was evaluated.
