Concrete Block - Various Finishes
Architectural concrete blocks with finishes such as split face, honed and shotblast. Adbri notes split face has a natural raw face, honed removes the surface layer to reveal aggregate, and shotblast uses a light abrasive process to expose stone. Manufacturer ranges include 390 x 190 modules in 90/140/190/290 series widths, and product data cites manufacture to AS/NZS 4455.1 and testing to AS/NZS 4456, with fire resistance determined to AS 3700.

Concrete block use expanded with mechanised block-making in the early 1950s; BRANZ reports Winstone began manufacturing Hollowstone blocks in 1953 using a Besser Vibrapac machine. The same BRANZ history notes that concrete masonry manufacture has been harmonised since 1983 under AS/NZS 4455.1.
