Study on the Optimization of Some Lime Based Mixing Binders' Characteristics

The mixing binder based on lime represents the optimal solution for replacing of the silicate cements in the general effort of sustainable development. The construction lime is obtained at temperatures of about 10000C with a moderate energetical consume at construction lime's obtaining the carbon dioxide is released that will be neutralised in the chemical hardening process of the slacked lime. The silicate cements replacing with mixing binders based on construction lime presents interest by an inferior energetical consume beside the silicate clinkers and allows the recycling of a several industrial byproducts. The paper presents the results of the research from the Building materials discipline from Faculty of Civil Engineering and Building Services from Iassy, Romania on the using of the industrial byproducts in construction field. Were analyzed the characteristics of the construction lime - thermal power plant ash mixtures in the fresh mixture state and as well, for the final hardened state mixture.
