Ceramic bodies for fast single-fired floor tiles containing argillaceous polymicte sandstone
A new polymineral raw materials, the agrillaceous polymicte sandstone, was investigated in order to test its applicability as a raw material for red ceramic bodies used for the production of floor tiles with lower water absorption. The chemical and phase compositions were determined by X-ray diffraction, IR spectroscopy, DTA and TG. Several technological properties were measured: the normal moulding moisture, plasticity of Pfefferkorn, air shrinkage and green mechanical bending strength. Standard methods were employed for the determination of the basic properties of argillaceous polymicte sandstone after firing: fire shrinkage, mechanical bending strength, water absorption, bulk density, apparent porosity and thermal linear expansion coefficient. The argillaceous polymicte sandstone was found to be a polymineral raw mineral, which is a transition between very highly acid clay and polymicte sandstone. Its microstructure is disordered and exhibits microgranularity. The main crystal phase is quartz, while the quantity of feldspar is lower and the clay component is a mica-type-illite. The results showed its use for compositions of ceramic bodies for wall tiles. Compositions were developed for fast single fired floor tile bodies containing the argillaceous polymicte sandstone. The bodies were characterized by low water absorption and low porosity. The dependence between the physical-mechanical properties and body phase composition was investigated.
