A method of forming an architectural concrete structure having a desired look (i.e., color) and texture, wherein the method generally includes pouring a base concrete layer using conventional concrete. A surface concrete mixture is prepared and includes a mixture of sand and small aggregates to give the surface concrete mixture the desired color and texture for the architectural concrete structure. The base concrete layer provides strength and durability to the concrete structure, while the surface concrete layer provides the desired look and texture of the concrete surface. The surface concrete mixture preferably includes small aggregates to create a smooth and uniform texture. 1. A method of forming architectural concrete , the method comprising the steps of:pouring a base concrete mixture in an unhydrated state to define a base concrete layer, the base concrete mixture including large aggregate;preparing a surface concrete mixture including small aggregate and sand, the small aggregate being smaller than the large aggregate used in the base concrete mixture, the small aggregate and sand being mixed to define a prescribed color; andpouring the surface concrete mixture over the base concrete layer while the base concrete mixture is in the unhydrated state, the surface concrete mixture defining a surface layer.2. The method recited in claim 1 , further comprising the step of forming a subgrade upon which the base concrete mixture is poured.3. The method recited in claim 1 , further comprising the steps of:providing a concrete form; andpouring the base concrete mixture within the concrete form.4. The method recited in claim 1 , further comprising the step of leveling the surface of the base concrete layer prior to pouring the surface concrete mixture over the base concrete layer.5. The method recited in claim 1 , further comprising the step of floating the surface concrete mixture after it is poured over the base concrete layer.6. The method recited in claim 1 , ...

SOUND ABSORBING WALL

Sound absorbing walls include a planar front panel element formed of an acoustically transmissive material and having a peripheral edge, a planar inner panel element formed of an acoustically absorbent material, having a peripheral edge, a front face abutting the front panel, and an opposed rear face, and a rigid frame having a panel portion overlaying the rear face of the inner panel element, and having a peripheral edge, and an edge portion forming a rim depending from the peripheral edge of the frame, and enclosing the peripheral edges of the front panel and inner panel. The frame may encapsulate the front panel and inner panel, except for an exposed front panel front surface. The rim may extend forward of the front panel. A sound wall may be constructed by connecting edge portions of one or more panels to spaced apart first and second ground-mounted vertical support columns. 1. A method of forming an acoustically absorbent panel comprising the steps:obtaining outer forms;obtaining spacer forms;obtaining an upper form;obtaining a panel board;obtaining rebar;obtaining weld plates;connecting together the outer forms to define a space;positioning the spacer forms within the space defined by the outer forms to define a peripheral gap between the spacer forms and the outer forms;placing the panel board on top of one of the spacer forms to define a peripheral gap between the panel board and the outer forms;positioning the rebar above the panel board;positioning the weld plates adjacent to the rebar;pouring concrete over the rebar until the space defined by the outer forms is filled;placing the upper form over the outer forms;waiting for the concrete to cure; andremoving the upper form, outer forms, and spacer forms from the panel board and the cured concrete to expose a finished acoustically absorbent panel.2. The method of wherein the upper form has a pattern on a portion that contacts the concrete such that a pattern is formed on the finished acoustically absorbent ...
