A substantially crack-free load-bearing wall of prefabricated building elements and method of producing the same comprising a plurality of pre-fabricated building elements made of light-weight concrete each having a modulus of elasticity less than 8,000 kg/cm.sup.2. The elements are substantially rectangular in shape and have longitudinal grooves on their respective longitudinal edges. The elements are first shrunk by steam hardening or by storage for a pre-selected period of time and then arranged side by side with their lateral side edges in abutting relationship so that the grooves of the respective adjacent elements form vertical channels therebetween. The channels are filled with heavy concrete which provides a tensile-resistant bond between the elements and which also forms pillars which carry the major part of any load applied to the wall.
A method of constructing a substantially crack-free load-bearing wall, comprising:
A substantially crack-free load-bearing wall, comprising a plurality of substantially rectangular pre-fabricated building elements of light-weight concrete having a modulus of elasticity less than 8000 kg/cm.sup.2 which have been previously shrunk by steam-hardening or storage, said elements having a lengthwise groove formed in each of their longitudinal side edges, said elements further being arranged side-by-side so that the longitudinal side edges of adjacent elements are in abutting relationship and said grooves form vertical channels between adjacent elements, said channels being filled with heavy concrete to provide a tensile-resistant bond between adjacent elements and to form pillars in said channels which carry the major part of a load applied to said wall, said previous shrinkage of said pre-fabricated elements being such that the residual shrinkage of the elements is accommodated by creep occurring in the elements and by elastic expansion thereof.
