Use of modified waste sludge from limestone washing into a form of alternative binder

Popis výsledku v původním jazyce

Waste sludge from mining and washing of limestone is a material that is in great amount stored in waste ponds, and its amount is still increasing, even though its composition can be useful for several purposes. It contains limestone, feldspars and clay minerals, that are also part of raw materials used for burning of cement clinker. This material can be used also for preparation of alternative binder. Its composition was modified by advantageous adding of other waste material containing mainly calcium oxide and silicon dioxide in form of tobermorite and xonotlite. These two materials were mixed together in different proportions with K2O addition and burned at 1150 °C and 1350 °C. The main products formed were lime, dicalcium silicate, rankinite, wollastonite and pseudowollastonite. The aim of this work was to prepare alternative binder based on these waste materials.
