Foam-Gas Concrete with Nanostructured Modifier
In this study the opportunity of application of nanostructured binder as modifier when production of heat insulating cellular concretes is theoretically justified and experimentally confirmed.Modifier initiates structuring of all elements of cellular composites such as cement matrix, providing the strength of composite, as well as foam-gas system as source of porestructure in composite. Also the efficiency of an activated aluminum application as gas forming agent as well as its ultrasonic distribution in water environment with nanostructuredmodifier is established. It leads to acceleration of distribution of disperse components in water as well as system stabilization in time. These methods allow realization of complex poreformation in binding system as well as formation of heteroporous structure of final composite. Totally, it provides a production of cellular composites with good thermal characteristicsand required strength properties.
