Building element consisting of a concrete body with at least one attached glass pane

摘要

A construction (1) made of concrete (2) with≥1 pane of glass (4) at the front has the following features: (1.1) the glass has a coating (5) of composite mortar (I) on the inside; (1.2) the mortar (I) consists of finely divided neutral aggregate and cement mixed with an aq. dispersion of a polyacrylic acid deriv. (II) with a max. logarithmic decrement (DIN 53445) < 0 degrees C; (1.3) mortar (I) is hardened on the glass with a deficiency of hydration water; and (1.4) the coating (5) forms a solid bond with the concrete (2). The amt. of deriv. (II) and the thickness of the mortar are adjusted so that thermal expansion of the glass occurs without cracking. Also claimed is a process for the assembly of this construction.
