Abstract of the Invention The present invention relates to lightweight fine ceramic particulates, directly obtained from fly ash, their use in different technical fields and building material compositions comprising the same. Lightweight fine ceramic particulates, especially sintered synthetic sand, as disclosed herein are characterized in that the grading of the particulates is as follows: Sieve size (mm) 2 1 0.5 0.2 Passing (mass-%) >98 55 to 80 30 to 45 2 to 4 Disclosed is further the use of lightweight fine ceramic particulates according to the invention as aggregate for construction purposes, especially in combination with fly ash. Lightweight fine ceramic particulates according to the invention are further used as additive in paint or coating formulations, as foundry sand, additive for waste water treatment, substrate for horticultural purposes, for hydroponic gardening, for green roofing purposes or for applications in geotechnics. Disclosed are also building material compositions in form of mortar or concrete, comprising the lightweight fine ceramic particulates according to the invention. The lightweight fine ceramic particulates according to the invention, and especially the building material compositions derived from them, are advantageous in respect to superior quality and workability, sound insulation and sustainability from internal curing.
Abstract:
The object of the invention is a method and an apparatus for the handling of an input material (7), such as fly ash, that is granular material when dry, in which method the input material (7) is sorted by grain size into different fractions (1F-6F) using a screen device (10) and/or one or more classifiers (15, 21) and/or a grinding device (19) and/or an air flow as an aid. The input material (7) to be sorted is conducted from its storage location (2) into the apparatus space (1) via the input (7a) for unsorted input material (7), in which apparatus space (1) the input material (7) is sorted and manufactured into an end product (9) comprising the desired maximum grain size and composition, the end product being transferred from the apparatus space (1) via an output (9a) to its storage location (3).
