Particle size distribution and structural changes in limestone
Sample preparation occurred in two rounds as follows. The blocks were crushed with jaw and roll crushers until all particles being < 1.7 mm. The crushed particles were ground in a porcelain ball mill in order to obtain particle sizes between 75 and 250 μm. After homogenization, 25 aliquots of 40 ml (~ 60 g)2.1.2. Filler. This study used limestone aggregates from a local quarry with a nominal size range of about 2.36–4.75 mm.

Quicklime preparation Gebr. Pfeiffer
The fineness of the white fine limes can be set within wide limits (0.06 to 0.1 mm). In downstream Pfeiffer lime hydrators, water is added to quicklime, thus transforming it into lime hydrate. White fine lime is used for the production of limestone bricks and aerated concrete. Lime hydrate is used for the production of plaster and mortar.The mixture was ball milled (Ceramic Instruments s2-1000 M, s303) with a weight proportion of 1:4:4 (raw materials:balls:water). To evaluate the influence of the milling time on the granulometric distribution different milling times were tested: 10 and 15 min for the limestone and 30, 60 and 90 min for the eggshell waste.Development of eco-ceramic wall tiles with bio-CaCO
