Study on the optimization of some cement based mixing binders' characteristics

The mixing binders based on construction cement have a reduced impact on the environment and allow the recycling of some artificial byproducts resulted from burning in the energetic industry, coals burning or natural such as volcanic tuffs with great resources in Romania. 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. The characteristics of the cement - thermal power plant ash mixtures in the fresh state and, as well for the final hardened state, where analyzed.
