A black and white marble background with a graphic design featuring a detailed architectural blueprint of a reinforced concrete structure in the center. the background features a large, ornate building engulfed in flames, with a fleur-de-lis emblem in the top left corner. The building appears to be a cathedral, with intricate carvings and a tall, spire-like structure. The text "Construction" is written in bold, white letters at the top of the image, with the words "reinforced concrete" written in smaller, black letters below it. Below the text, there are two smaller, white marble coasters with detailed architectural drawings of a cross-section of the structure. the coasters are placed on a dark, textured surface, giving the image a sense of depth and dimension.
