Abstract(s)

In the development of the study and interpretation of the new approaches on complementary cementitious materials, we have been developing, in a first step, a study of comparative analysis of the physical, chemical and mechanical characteristics of the ordinary cement CEM I 42.5 R produced by CIMPOR [1] . We will use matured and unripened slag resulting from the incineration of municipal solid waste processed by LIPOR [2] . In this laboratory study, the materials were first submitted to a differentiated grinding process in a ball mill, and subsequently used to the tests of particle size analysis by laser diffraction in the range of particles between 0.04 m to 2000 m. This was followed by fineness determination tests according to NP EN 196-6 and subsequently manufactured various types of hybrid mortars,(with a cement/slag ratio=4) and moulding of the respective specimens. Finally, they were all submitted to mechanical compressive strength tests at 7, 28 and 90 days, according to NP EN 196-1. Finally, the results were analyzed and discussed.
