Abstract:
The binder, particularly cement, contains, based on the total weight of the mixture, up to 99 % of cement clinker by weight, from 0.5 to 99 % of fluid fly-ashes by weight, up to 99 % of siliceous fly-ashes by weight and/or calcaeous fly-ashes and/or other components selected from the group comprising slag, pozzolana, tuffs, diatomaceous earth, etc. while the rest consists of impurities. A method for the production of the binder is also claimed.
Abstract:
Cement containing 5-99% of a finely ground inorganic substance having various specific surfaces, chemical compositions and physical properties, e.g. cement clinker and 1-95% of fine powder having hydraulic and/or pozzolana properties, with required specific surfaces, chemical composition and physical properties, e.g. natural pozzolana, industrial pozzolana, fly ashes, slags, tuffs, trasses, volcanic glass, calcined shale, limestone, etc., which is added to and mixed with the finely ground inorganic substance with various specific surfaces, chemical compositions and physical properties, creates a paste after mixing with water that sets and hardens due to hydration reactions and processes. The setting is controlled by means of a suitable adjustment of the ratios of water, the finely ground inorganic substance, e.g. cement clinker and the fine powder with hydraulic and/or pozzolana properties.
