Abstract
The characteristic flexural strength of low density Aircrete wallettes (2.8 and 2 N/mm 2) incorporating both conventional and thin layer mortar is verified. The wallettes are tested in accordance with BS EN 1052-2. The flexural strength of Aircrete wallettes is derived from the strength of small specimens tested to destruction under four-point loading. The strengths of the wallettes are high with impressive repeatability with the maximum strength being reached for thin layer wallettes within 7 days curing time. In general the strengths of both conventional mortar and thin layer mortar wallettes compare favourably to values reported in BS 5628. © 2005 Taylor & Francis Group.
