Get PriceConcrete is considered to be lightweight is the density is not more than 2200kg/m 3 (the density of normal weight concrete is assumed to be between 2300kg/m 3 and 2400kg/m 3) and a proportion of the aggregate should have a density of less than 2000kg/m 3. Lightweight concrete can be specified using the notation LC for the strength class e.g ...

Get PriceGeorge Wypych in Handbook of Adhesion Promoters 2018. 3.3 DETACHMENT. Adhesion of mortars to concrete and brick walls is a complex mechanism that is affected by several factors. 14 The adhesion loss leads to mortar detachment from the substrate which may cause hazardous situations to passers-by. 14 Without mortar the wall is directly exposed to the atmosphere and therefore its degradation ...
