Review on Cement Stabilization/Solidification of Municipal Solid Waste Incineration Fly Ash

Table 3

MSWI fly ash immobilized with different cementitious matrix materials.

Cement	Advantages	Disadvantages
Portland cement	(1) Simple operation	(1) High capacity and weight increased rates
	(2) Low cost	(2) Poor long-term security and stability
	(3) Moderate compressive strength
Phosphate cement	(1) High compressive strength	(1) High capacity and weight increased rates
	(2) Good dry shrinkage	(2) Poor long-term security and stability
	(3) Low cost
Aluminate cement	(1) Simple operation	(1) High capacity and weight increased rates
	(2) Low cost	(2) Poor stability
		(3) Poor dry shrinkage
Alkali activated cement	(1) High compressive strength	(1) High capacity and weight increased rates
	(2) Low cost	(3) Poor dry shrinkage
	(3) Good long-term security and stability
