Exposed Aggregate: Stones Peeking Out

An exposed aggregate concrete surface. The surface layer of cement paste has been washed or chipped away, revealing the crushed stone aggregate within, with particle sizes ranging from a few millimeters to two centimeters, in a mix of gray, white, and light brown colors. The surface is therefore rough and uneven, like an artificial conglomerate. It is used on a section of a wall or a column, contrasting with the smooth formwork surface next to it. Avoid: making the entire space exposed aggregate, grinding and polishing the aggregate into terrazzo, using veneers to simulate, making the aggregate particles perfectly uniform in size.

一片骨材外露的混凝土表面。表層的水泥漿被沖洗或鑿掉,露出裡面的碎石骨材,顆粒的大小從幾公釐到兩公分不等,顏色是灰、白與淺褐的混合;表面因此是凹凸粗糙的,像一片人造的礫岩。它用在一段牆或一根柱上,與旁邊平滑的板模面形成對照。避免:讓整個空間都是骨材外露、把骨材磨平打光成水磨石、使用貼片模擬、讓骨材的顆粒大小完全一致。
