Peculiar features of silicate materials curing

Abstract

The papers on contact-condensing (non-autoclave) curing of silicate materials point at the expediency of technology development. Non-autoclave silicate products of M 100 … 300 grades can be used in low-rise and individual housing construction. The complexity of practical implementation of the technology associated with the processes occurring in the field of highly dispersed phases requires research on micro capsulation of hydro silicate binder, in particular, the maintenance of its properties in technological redistribution. High surface energy of newgrowth causes particle clustering. It is desirable to obtain aggregates characterized by the lowest energy of their total intercrystallite interaction. Main mechanism of directed structure formation at the boundaries of the sections of the given binder is ultradisperse particles with a high adsorption capacity and adhesive ability, the main purpose of which is to strengthen the contact zone. The novelty of the proposed solutions lies in the fact that contact formation zone is presented as a multilayer system having different rheological characteristics. The study and description of contact-condensing processes occurring in unstable hydrosilicate systems as well as the sol-gel technologies are the important aspects in the foundations development of modern material science, the creation of materials and new generation products.

Mineral Formation of Autoclaved Binders Using Amorphized Raw Materials

“…As it is known, in the traditional technology of silicate autoclaved materials, quartz is the main silica component of the binder in the CaO -SiO2 -H2O system as a rock-forming mineral of the traditionally used sands [4][5][6][7][8][9]. At the same time, its solubility increases during high-pressure steam treatment.…”
