We have performed experimental examinations for the purpose of proposing a floor finishing structure with superior effects in terms of combating heavy-weight floor impact sound. We have developed a box floor with ease of construction and excellent heavy-weight floor impact sound insulation performance and examined its effect with a 1200 × 1200 mm test piece connected to inter-noise 2020. The box floor has a floor finishing structure with anti-vibration and sound insulation measures aimed at improving measures against heavy-weight floor impact sound. We herein report the results of a basic examination on the reduction of the transmitted heavy-weight floor impact sound of a box floor structure in a reinforced concrete wall construction testing device when the area is further expanded to about 10 . As a result, with the air layer under the box floor open, the floor impact sound level was reduced by 9 dB in the 63-Hz band compared to the bare surface. In addition, with the air layer at the bottom of the BOX floor sealed, the floor impact sound level was reduced by 5 dB in the 63-Hz band compared to the bare surface.

Building Methods

In the poetics of Álvaro Siza, the enriching experience of making architecture on site has always been very important; but even though his work has been widely recognized, published and discussed, little is known about the construction strategies employed. This paper reviews Siza's use of reinforced-concrete wall construction to create, through a process of subtraction and a search for the essential, building forms of a very particular kind.

New Rural Construction

Tilt-up is a method for constructing concrete wall rapidly and economically without formwork. A large number of tilt-up structures have been constructed in North America and other developed countries, and it will also be an acceptable term for new rural construction in China. Tilt-up process can reduce the cost of labor and materials in wall construction. With the application of the recycled concrete in tilt-up construction, which is being researched in the Beijing University of Civil Engineering and Architecture, tilt-up building can be has a larger benefit obviously in the suburbs and rural area. With the benefit of both techniques, the paper finally introduces the application prospect in China.
