Badanie granulometrii pyłów ceramicznych powstających podczas rozkruszania odpadów ceramiki sanitarnej pod kątem wykorzystania ich jako dodatku do betonu

Examination of granulometry of ceramic dust which derogations while disposing waste sanitary ceramics for the use of their as addition to the concrete

Abstract

The purpose of the research presented in this article was to assess the granulometry of ceramic dust in terms of their use as an additive to concrete. The material for testing came from postindustrial sanitary ceramic waste, which was subjected to a crushing process in jaw crushers. A research stand consisting of a Horoir LA-300 laser particle analyzer connected to a computer equipped with appropriate software was used to study the granulometric characteristics. As a side feature, the dust density was examined using a Le Chatelier flask. The results of the tests carried out were compared with the data obtained for the traditionally used concrete additive - silica volatile dusts.
