Manufacturing of Concrete Products and Precast Elements


Book Description

The flexible use of prefabricated concrete products requires a continuously increasing diversity with regard to fresh concrete mix designs and properties, moulding processes, surface finishes and product characteristics. This trend imposes ever-higher requirements on manufacturers of the associated production equipment and on precast plants. The main goal is to implement a flexible production system in all processing stages. The relevant correlations and interactions need to be thoroughly considered and evaluated in order to ensure that concrete products and precast elements are manufactured to the required quality standard. To date, no comprehensive description of these correlations has been published in the relevant literature. This richly illustrated book closes the gap by describing the basic principles of the production processes, the fundamentals of materials, the composition of the concrete mix, and the equipment used for concrete production. Clearly arranged chapters detail the production processes and equipment used to manufacture small concrete products, concrete pipes and manholes, and precast elements. The authors have used their many years of experience in the field of precast technology and their close ties to the industry. Their aim was to integrate modern testing and calculation methods from neighbouring disciplines into precast technology. This includes, for instance, modelling and simulation of the workability behaviour of mixes, implementation of the latest advancements in machine dynamics to the design and engineering of production equipment, and the use of stateof-the-art measuring and automation technology for quality control purposes.

Precast Concrete Structures


Book Description

This second edition of Precast Concrete Structures introduces the conceptual design ideas for the prefabrication of concrete structures and presents a number of worked examples that translate designs from BS 8110 to Eurocode EC2, before going into the detail of the design, manufacture, and construction of precast concrete multi-storey buildings. Detailed structural analysis of precast concrete and its use is provided and some details are presented of recent precast skeletal frames of up to forty storeys. The theory is supported by numerous worked examples to Eurocodes and European Product Standards for precast reinforced and prestressed concrete elements, composite construction, joints and connections and frame stability, together with extensive specifications for precast concrete structures. The book is extensively illustrated with over 500 photographs and line drawings.




First RILEM International Conference on Concrete and Digital Fabrication – Digital Concrete 2018


Book Description

Digital fabrication has been termed the “third industrial revolution”, and is promising to revolutionize many disciplines, including most recently the construction sector. Both academia and industry see immense promise in cementitious materials, which lend themselves well to additive manufacturing techniques for digital fabrication in construction. With this recent trend and high interest in this new research field, the 1st RILEM International Conference on Concrete and Digital Fabrication (Digital Concrete 2018) was organized. Since 2014, ETH Zurich has been host for the Swiss National Centre for Competence in Research (NCCR) for Digital Fabrication in Architecture, which is highly interdisciplinary and unique worldwide. In 2018, this NCCR opened the “DFAB House”, which incorporates many digital fabrication principles for architecture. It is also responsible for the 600 m2 Robotic Fabrication Lab and the first robotically built roof in the world. Held in tandem with Rob|Arch 2018, the leading conference for robotics in architecture, RILEM deemed it the right time to combine forces at this new conference, which will be the first large conference to feature the work of the recently created RILEM Technical Committee on Digital Fabrication with Cement-based Materials, among other leaders in this new field worldwide. This conference proceedings brings together papers that take into account the findings in this new area. Papers reflect the varying themes of the conference, including Materials, Processing, Structure, and Applications.

Composite Precast Systems


Book Description

Hybrid Composite Precast Systems: Numerical Investigation to Construction focuses on the design and construction of novel composite precast frame systems that permit almost effortless erection and structural efficiency. The precast frame systems discussed in the book are similar to that of steel frames, but offer similar savings to concrete frames. The design of connections and detailed analysis of their structural behavior is discussed in detail. Fundamentals with regards to the post yield behavior of concrete and metal are also presented to illustrate how these two different materials are integrated together to remove individual material drawbacks. Readers are given a broad introduction to existing technologies that are then combined with a description of the construction methods the author proposes. This book will help the end users become familiar with the existing types of structural forms, not just the "Lego" type frame system that the author proposes. Discusses how traditional construction methods can be replaced by innovative hybrid composite precast frame systems that provide rapid and effortless erection capabilities and structural efficiency Contains several design examples using non-linear finite element analysis completed with Abaqus based-software Contains new milestone inventions in construction that offer structural engineering solutions using a novel, modularized hybrid frame system Provides information on structural testing that verifies the accuracy of the structural design
