Disclosed herein is an earthquake-resistant rammed earth structure. The earthquake-resistant rammed earth structure includes an armed scaffold located inside a rammed earth wall. The armed scaffold includes a foundation at the bottom, a bond beam at the top, two concrete columns at two respective corners extending from the foundation to the bond beam, a mesh network with a zigzag arrangement continuously extending from the foundation to the bond beam, a strand of barbed wire perpendicularly woven into the mesh network, a plurality of parallel vertical rebars extending from the foundation to the bond beam, a plurality of parallel horizontal rebars extending between the two concrete columns, a plurality of U-shaped fasteners fastening the plurality of vertical rebars, the plurality of horizontal rebars, and the mesh network together, and a plurality of transverse connectors transversely interlocking the rammed earth wall and the armed scaffold.

A modular wall is a permanent external frame solution for a building. It includes outer panels and inner panels each made of high impact thermoplastic polymer, eliminates the need for removable formwork, reduces construction time and improves insulation and waterproofing. The panels join together in a locking connection by snapping or sliding an end of a first panel to an opposite end of an adjacent second panel. Reinforcing metal pipes connecting each outer panel to a corresponding inner panel occupy a negligible amount of space where the concrete is to be poured so as not to obstruct rebar. Quality control is enhanced since the panels may be transparent to monitor the concrete casting. Each of the outer panels and inner panels may include two substantially parallel walls separated by a pattern of reinforcing ribs that together with the substantially parallel walls define spaces for heat insulation and increase structural integrity.

Insulated hollow core concrete forming system provide a forming system which can integrate the advantages of the hollow core design into the Insulated concrete form (ICF) system. The Insulated hollow core form system includes one or more of a Modular formwork unit, composed and formed of insulative material, where the Modular formwork unit utilizes longitudinal void formers that crafts a forming cavity of a hollow core section in between two spaced parallel side panels. The forming cavity is disposed to receive concrete or other hardening materials to form an insulated hollow core wall or an insulated hollow core slab. The system also includes a furring strip assembly positioned between adjacent Modular formwork units to join them together.
