Influence of Expansion on Properties and Microstructure of Calcium Silicate Composite Material

Popis výsledku v původním jazyce

The aim of the research was verification of influence of aeration and influence of aluminum powder on microstructure and physical mechanical properties of calcium silicate composite material. At the same time, influence of various dosages of alternative raw materials on porous structure of the composite was examined. Tested raw materials are not the ones commonly used in the technology of manufacture of calcium silicate composites, for example chamotte blocks, Lining of silica and foundry sand. It was found that influence of aeration of calcium silicate composite causes reduction of compressive strength by roughly 85%. At the same time, volume weight drops by 50%. As a consequence of the expansion, intensity of diffraction lines of tobermorite detected by X-ray diffraction analysis is reduced because of reaction of aluminum powder with calcium hydroxide. It was found that there is dependency between the amount of replacement of silica sand with foundry sand and silica, and intensity of tobermorite diffraction lines, where the intensity of the diffraction lines was reduced with increased amount of replacement.
