Abstract:A new cement manufacturing technology that utilizes incinerator ash up to 50% of raw materials has been developed. This cement is called Eco-cement. Eco-cement is a new type of Portland cement being developed not only to solve the municipal and industrial waste problem caused by limited availability of landfill sites, but also to contribute to the protection of the environment by providing a complete recycling system of wastes that would otherwise be dumped. There are two types of Eco-cements, one is rapid hardening type that contains about 0.5 to 1.5% of chlorine, the other is normal type that contains relatively low chlorine and shows similar properties to normal Portland cement. In this study, strength development, mechanical properties and drying shrinkage. autogenous shrinkage and crack resistance of concrete made with normal type of Eco-cement was compared with that of concrete made with normal Portland cement and low-heat Portland cement. Drying shrinkage of concrete made with normal type of Eco-cement is not very different from that made with normal Portland and low-heat Portland cements. However, cracking resistance of concrete made with normal type of Eco-cement is remarkably higher than that made with normal Portland and low-heat Portland cements.
