    Wpływ zeolitów klinoptilolitowych na mikrostrukturę i skład fazowy stwardniałych zaczynów żużlowo-alkalicznych

    Modification of slag-alkaline slurries with mineral additives to obtain a new generation injection binders is one of the methods of making the so-called geopolymer binders. Addition of natural zeolites creates a possibility of intensifying puzzolan reactions in slag-alkaline slurries, and also their sealing and enhancing the formation of zeolites in the slag-alkaline matrix. The many years' experience shows that the processes of zeolite formation in a slag-alkaline matrix in the conditions of natural maturing take place slowly. Only the hydrothermal conditions to which the slag-alkaline slags are exposed cause that the processes radically accelerate and zeolites are formed. Addition of natural klinoptilolit zeolites may result in an unstable acceleration of zeolites and also hydrogranates formation"," the latter are responsible for the durability and immobilization potential of the slag-alkaline matrix. The results of analyses of fresh and hardened slurries with addition of Slovak klinoptilolitowych zeolites maturing in natural and hydrothermal conditions typical of deep well cementation processes, are presented in the paper.

    Zaczyny geopolimerowe do prac iniekcyjnych
    (2006) Brylicki, Witold; Stryczek, Stanisław; Gonet, Andrzej
    Injection works carried out for sealing and reinforcing the rock mass have been usually performed with the use of sealing slurries based on classical cement binders, cement-clay, clay, gypsum and their compositions with mineral and swelling additions. Sometimes also costly polymer and cement-polymer slurries are used. The results of analyses of fresh and hardened geopolymer slurries obtained in laboratory conditions of both Faculties are presented: results of analyses of technological parameters of fresh and hardened slurries, i.e. strength parameters, microstructure and microporosity.
