An adhesive composition, in particular a tile adhesive, includes: a) 10-50 wt. % of a hydraulic binder, b) 20-60 wt. % of lightweight aggregates, c) 10-25 wt. % of a polymer.

Disclosed is a liquid regulator for ultra-dispersed, high-mud-resistance, high-foam-stability, low-shrinkage and enhanced autoclaved aerated concrete, which comprises the following ingredients in parts by weight: 75 parts to 85 parts of hyperdispersant; 5 parts to 10 parts of anti-mud agent; 1 part to 3 parts of shrinkage reducing ingredient; 10 parts to 20 parts of reinforcing ingredient; and 0.05 part to 0.1 part of foam stabilizing ingredient; and the invention further discloses a preparation and application thereof. By adding the liquid regulator into the autoclaved aerated concrete, the effects of ultra-dispersion, high mud resistance, high foam stability, low shrinkage and performance enhancement can be achieved.

Dry mortar mixture characterized by a glass mixture of expanded glass beads with a grain size d/D 0/8, mixed in a ratio of between 1:1 and 1:3, with a binding mixture of hydraulic binders and stone granules in the weight ratio of 1:2 to 1:4. The glass has a discontinuous grain distribution. For the glass mixture the fractions 0.5/1.0 and 2.0/4.0 are present while a fraction intermediate other fractions are absent. Preferably the fractions 0.25/0.5 and 1.0/2.0 are absent. For the glass mixture preferably all grain sizes between 1.0 and 2.0 mm are absent. The grain size distribution is around an average, so that an open structure is obtained.
