The influence of heat on elastic properties of illitic clay Radobica

Popis výsledku v původním jazyce

Brick clay from a locality Radobica, Central Slovakia, which was exploited for brick manufacturing in the past, was investigated for its possible reuse in the brick industry. The crystalline phases of the green sample were 48 % of quartz, 37 % of illite,13 %, of Na-feldspar and 2 % of calcite. The measurements of Young?s modulus of clay samples were performed during heating up to 1100 °C and also at room temperature on samples preheated at temperatures from 100 to 1100 °C. It was found during firing that 1) the physically bound water is released in 3 steps (up to 300 °C) and reaches 2.5 wt%. The thermal expansion is decelerated by setting the crystal closer at low temperatures. Young?s modulus increases in its values (36 %) which is a result of the closer structure that is created via release of the physically bound water. 2) The mass loss during dehydroxylation (450 ? 750 °C) is 3 wt%. The superposition of dehydroxylation and ?=? transformation of quartz creates a step 3 % of the rel
