A connectable panel for a stay-in-place modular concrete formwork system neatly stacks with other identical connectable panels. In a stack of such panels, the connecting means at either end of a particular connectable panel is protected from bending and distortion from the weight of other panels above it. Each connectable panel has a middle section and connecting means at two connecting sections at opposite ends of the panels. The sum of the widths of the two connecting sections, including their respective connecting means, is equal to or less than the width of the middle section including projections extending from the middle section.

Formwork for cylindrical structures of varying diameters may be assembled with the connectable panels, connectors, and a series of identical insulation inserts.
A method for producing thermally insulated concrete by making use of treated, and preferably recycled, plastic as an aggregate ingredient. In particular, plastic elements are coated with cement and/or sand to render the surfaces of the plastic elements rough in order to better bond and mix more uniformly in a concrete mixture in forming concrete.
B28C 5/00 - Apparatus or methods for producing mixtures of cement with other substances, e.g. slurries, mortars, porous or fibrous compositions
C04B 18/20 - Waste materialsRefuse organic from macromolecular compounds
C04B 28/00 - Compositions of mortars, concrete or artificial stone, containing inorganic binders or the reaction product of an inorganic and an organic binder, e.g. polycarboxylate cements
C08J 5/12 - Bonding of a preformed macromolecular material to the same or other solid material such as metal, glass, leather, e.g. using adhesives
A stay-in-place concrete formwork system allows stucco to be applied directly to the formwork, avoiding the need to provide a further surface treatment of the wall prior to applying stucco. Apertures are provided on an exterior facing wall of the formwork panel to receive and embed stucco therein. The panel may also be formed with outward stucco-engaging projections. Other features include using rigid insulation to brace the stucco and keep concrete from the apertures, a sealing joint element, extendible panels for use in curved formwork, rainscreen features and an alligator connector panel for adjustable lengths of formwork faces.
E04B 2/86 - Walls made by casting, pouring, or tamping in situ made in permanent forms
E04G 9/10 - Forming or shuttering elements for general use with additional peculiarities such as surface shaping, insulating or heating, permeability to water or air
E04G 11/06 - Forms, shutterings, or falsework for making walls, floors, ceilings, or roofs for walls, e.g. curved
