BLSI 分享 | UHPC（超高性能混凝土）

2023-08-18

UHPC（超高性能混凝土）是一种具有高强度、高韧性、孔隙率低的水泥基材料。它通过提高组织成分的细度与活性，使材料内部的孔隙与微裂缝减到最少，从而获得超高强度与耐久性，是过去三十年中最具创新性的水泥基工程材料。UHPC主要以“三高”著称，即强度高、耐久性高、工作性高。

UHPC (Ultra High Performance Concrete) is a cement-based material with high strength, high toughness, and low porosity. It achieves ultra-high strength and durability by improving the fineness and activity of tissue components, minimizing internal pores and microcracks, making it the most innovative cement-based engineering material in the past thirty years. UHPC is mainly known for its "three highs", namely high strength, durability, and workability.

上音歌剧院，上海 / Christian de Portzamparc

上音歌剧院位于汾阳路和淮海路的交汇处，以宽敞的公共入口敞开于原法租界的重要道路。不同于大型的单体建筑，这座歌剧院由一系列场馆组成，与周围建筑的步调保持了高度的一致。每个场馆的色彩和肌理均受到了砌砖图案的启发。

This new opera is located on Fenyang and Huaihai Road. The building opens with a large public entrance at the corner of these two important streets of the historic French Quarter. Rather than massive one-room construction, the opera is conceived as a series of pavilions, harmonizing with the pace and height of the surrounding buildings, including the recent conservatory on Fenyang Street. The color and texture of the pavilions are inspired by the brick patterns.

佩雷斯艺术博物馆 / Herzog & de Meuron

迈阿密佩雷斯艺术博物馆（PAMM）位于迈阿密公园，是比斯坎湾市中心滨水区再次开发项目的一部分。佩雷斯艺术博物馆同时朝向公园、海域和城市风光，从四面八方看上去都是一个开放且吸引人的结构形态。混凝土和木材以多种不同的方式进行排列组合，反映了建筑的外部材料。典型的干式墙的细节处理使得它们在主结构上清晰可见。

The Miami Perez Museum of Art (PAMM) is located in Miami Park and is part of a redevelopment project in the downtown waterfront area of Biscayne Bay. The Perez Museum of Art is simultaneously oriented towards parks, sea areas, and urban scenery, appearing as an open and attractive structural form from all directions.

Concrete and wood are arranged and combined in various ways, reflecting the external materials of the building. The detailed treatment of typical dry walls makes them clearly visible on the main structure.

阿布扎比卢浮宫 / Louvre Abu Dhabi

基于传统的阿拉伯建筑文化，普利兹克奖得主让·努维尔为阿布扎比卢浮宫找到了其独有的内涵。通过对场地语境的考量，努维尔将其打造成了一座海洋中的“博物馆之城”。一系列鲜明的白色体量源于麦地那及阿拉伯地势低洼的房屋。这座“城市”共计有55栋独立建筑，其中包含了23间画廊。建筑群的立面由3900块高性能纤维混凝土（UHPC）构成。

Pritzker-prize winning architect Jean Nouvel sought inspiration for the concept of Louvre Abu Dhabi in traditional Arabic architectural culture. Taking a contextual approach to the site, Nouvel designed Louvre Abu Dhabi as a ‘museum city’ in the sea. Its contrasting series of white buildings take inspiration from the medina and low-lying Arab settlements. In total, 55 individual buildings, including 23 galleries, make up this museum city. The façades of the buildings are made up of 3,900 panels of ultra-high performance fibre concrete (UHPC).

“马赛曲”大楼 / 让·努维尔建筑事务所

在法国马赛，同样出自让•努维尔之手的马赛曲大楼，立面由3850个独立的UHPC（超高性能纤维增强混凝土）遮阳结构组成，由底部一直延伸至屋顶，像一个框架罩着整体，在每一个细节构件上都着上相应的颜色，阳光下产生的光影效果使办公大楼看上去更加绚丽。

In Marseille, France, the Marseille Building, also designed by Jean Nouvel, features a facade consisting of 3850 independent UHPC (Ultra High Performance Fiber Reinforced Concrete) shading structures that extend from the bottom to the roof, forming a framework that covers the entire structure. Each detail is colored accordingly, and the light and shadow effects generated by sunlight make the office building look even more magnificent.

萨拉戈萨桥 / 扎哈·哈迪德

萨拉戈萨桥（西班牙语：Pabellón Puente），亦称蓬桥馆、桥亭，位于西班牙萨拉戈萨，横跨埃布罗河，长度为270米，是2008年世界博览会的三大主题馆之一，也是扎哈·哈迪德设计的代表性建筑之一。该桥是西班牙唯一具有室内空间需求的桥梁。建筑通体白色，结构主体为UHPC材料。其外形酷似一株剑兰，构连两岸。桥的内部桥馆分为两层，总共约3,100平方米。内部的大型的展示厅，为世博会的主题展览提供展示空间，建筑的顶部由金属板重叠而成，构思取材自鱼的鳞片。

The Pabell ó n Puente Bridge (Spanish: Pabell ó n Puente), also known as the Poente Pavilion or Bridge Pavilion, is located in Zaragoza, Spain. It spans the Ebro River and is 270 meters long. It was one of the three major theme pavilions of the 2008 World Expo and one of the representative buildings designed by Zaha Hadid. This bridge is the only one in Spain that has indoor space requirements.

The entire building is white, and the main structure is made of UHPC material. Its shape resembles a sword orchid, connecting the two sides. The interior of the bridge is divided into two floors, totaling approximately 3100 square meters. The large exhibition hall inside provides exhibition space for the theme exhibitions of the World Expo. The top of the building is made of overlapping metal plates, and the concept is based on the scales of fish.
