Musique concrète (French: [myzik kɔ̃kʁɛt]; lit. '"concrete music"') is a type of music composition that utilizes recorded sounds as raw material (Editors ).Sounds are often modified through the application of audio effects and tape manipulation techniques, and may be assembled into a form of montage (Editors ).It can feature sounds derived from recordings of musical instruments Derivative forms: Industrial music, noise music, .   Q.: As we are more and more concerned with durability, how do we measure it on a given structure after a year or after 5 years? A.: If you are thinking about both surface condition and structural integrity you should consult the ACI Standard, "Guide for Making a Condition Survey of Concrete in Service," which appears in Part I of the ACI Manual of Concrete Practice.   Reinforced concrete shear walls are critical structural components in gravity and lateral force resisting systems.

The performance of concrete structures varies over time due to environmental conditions and other factors. The examination on whether such change is in acceptable range is described in the JSCE Standard Specifications for Materials and Construction.

Evaluating Cracking in Concrete 7 THERMAL STRESSES Volume differentials are likely to develop in the concrete when different temperatures occur across a concrete section.

The concrete then cracks when the tensile stresses imposed by a change in volume differential exceed that of its tensile strength. Thermal stresses usually cause cracking in massFile Size: KB. This paper presents the fresh, mechanical, and durability performance, of a structural concrete mix classified as C-1, by the Canadian Standards Association (CSA) made with controlled quality Recycled Concrete Aggregate (RCA).Cited by: It is very important to investigate the effects of the seismic performance of corrosion-damaged reinforced concrete (RC) members, in terms of their strength and lateral deformability, on the seismic performance of entire building systems.

Such investigation allows accurate evaluation of the seismic performance of RC structures with corroded members, including beams and by: 2. The aim of this book is to present the most advanced materials and construc-tion techniques used in the reinforced concrete structure industry.

Because advanced materials are growing parallel to the development of new structure systems, the advantages and disadvantages of the different structure systems are very important.

Advanced Materials and Techniques for Reinforced Concrete Structures, Second Edition discusses both traditional and new systems in concrete structures, outlines the advantages and disadvantages of each system and its importance to construction durability and reliability, and presents the latest advanced materials and construction techniques currently used in reinforced concrete structures.

Ultra High Performance Concrete (UHPC) is a new type of composite material with high strength and high toughness, which has broad application prospects in engineering practice.

The Canterbury Earthquake Royal Commission report revealed that some reinforced concrete walls that are designed according to the New Zealand Standards (NZS ) () and detailed to comprise the seismic force resisting system of buildings did not achieve their expected ductile capability.

The report indicated that the reason was the formation of a primary flexural crack at the expected plastic Cited by: 9. Therefore, the corroded high-performance concrete and reinforced concrete should be investigated under different experimental tests, which lead to evaluating the performance of these concretes.

Recent progress in measurement techniques have given rise to increasing interest in non-destructive testing. Incorporating non-conventional, recycled materials in concrete (i.e. rubber crumbs from discarded tires), the heterogeneity is increased. Based on this, it is of importance to determine to what degree the accepted protocols, valid for traditional materials, are applicable to Author: Mihai Sergiu Stratulat, Oana Mihaela Banu, Ana Maria Toma, Petru Mihai, Ionuț Ovidiu Toma.
