Hello Civiea users. I am interested in books about ''Glass Fiber Reinforced Concrete (GFRC), Polymere Concrete'' mix design books.
For those who dont know what this kind of concrete is. These kind of concrete are widly used to replace Marble ard Ceramik and porcelain in farious filed like bathroom Sinks production, bath tubes productions and things like that. Any help would be appreciated. Thank you in advance.

GUIDANCE DOCUMENT ON THE IMPLEMENTATION OF STRUCTURAL EUROCODES
Author: Mark Neave, Peter Clapham, Jon Shave, Steve Denton, Chris Hendy | Size: 2.11 MB | Format:PDF | Publisher: ADEPT | Year: 2010 | pages: 190
The implementation of Eurocodes will bring significant changes to how structures are designed and specified. This in turn raises the need for changes in processes for the procurement, technical control and management of the design and construction of structures. ADEPT members, as structures owners, will be assessing the changes required to their policies and procedures due to the implementation. A central ADEPT guidance document will support a common understanding among ADEPT members and a consistent approach to the implementation of Eurocodes and management of their impacts on the procurement, design and construction of structures. The main purpose of this guidance document is to provide ADEPT members with clear and authoritative guidance and recommendations on addressing the issues arising from the implementation of Eurocodes. The document includes an overview of the Eurocodes, their legal status and implementation requirements, identifies the necessary changes in established processes and procedures, and highlights specific challenges for local authorities, and how these can be tackled effectively. The document also aims to assess and analyse the different needs of various groups of staff for Eurocode training, and offers guidance on the development of training programmes for both technical and non-technical staff, to enable them to reach a level of awareness, knowledge and understanding appropriate to their role, in a timely and cost-effective way. The guidance offered is not prescriptive, but rather enables ADEPT members to adapt the implementation approach to meet their own particular needs and circumstances. The guidance will provide a framework for specific policies on Eurocode implementation to be drafted by individual ADEPT members. It should be noted that the main focus of this document is on policies and principles, not technical details – although the training programmes outlined will enable those who need to have detailed technical knowledge to identify the most appropriate sources of information and guidance. The information provided may form the basis for future regional workshops to disseminate knowledge and experience, and should enable readers to hold informed conversations regarding the implementation and use of Eurocodes. Specific guidance on key roles undertaken by ADEPT members, and the challenges presented by the change, are also considered, for example, in relation to the Technical Approval process.

Much has been written in the trade press and in research papers regarding the potential for prefabricated and off-site methods of manufacture to bring both increased speed and enhanced quality to UK construction projects. The Department of the Environment Transport and the Regions (DETR) and the precast concrete industry have noted this interest and have been pro-active in seeking to establish the true extent of this trade and public interest in factory production techniques. These techniques have been supported by Sir John Egan’s ‘Rethinking Construction’ report as the way forward for improving quality and speed of construction. House building in the UK is a major industry but much potential exists to further develop the design, construction, procurement and aftercare of new build homes. The basic construction technology used relies mainly on traditional skills and materials; these are still used in the majority of new housing projects. Although the construction industry has previously been known for its tardiness in adopting new techniques, there is renewed interest in assessing the scope for prefabrication and industrialised building techniques. It is with this background that the Precast Housing Feasibility Study Group was established in March 1999 to review the use of precast concrete in the low-rise domestic housing market, as individual components or as integrated modular forms of construction. The findings of the Precast Housing Feasibility Study Group are presented in this publication which aims to assess the feasibility of using precast concrete elements to build cost effective and aesthetically pleasing low-rise dwellings that meet occupiers’ expectations and comply with the Building Regulations.

sites for the purposes of assessing their suitability for the construction of civil engineering and building works and of acquiring knowledge of the characteristics of a site that affect the design and construction of such work and the security of neighbouring land and property. It has been assumed that in the selection of construction sites due regard has been paid to the wider environmental and economic considerations affecting the community generally. More than one site may require detailed investigation before the final choice is made.
In this code, the expression Site Investigation has been used in its wider sense. It is often used elsewhere in a narrow sense to describe the exploration of the ground, which in this code has been termed Ground Investigation. It is to be noted, however, that although the treatment of ground investigation is detailed, the treatment of other aspects of site investigation is less detailed. The use of soil and rock as construction materials is treated only briefly; further information is given in BS 6031. This code of practice consists of the following sections:
— Section 1: Preliminary considerations;
— Section 2: Ground investigations;
— Section 3: Field investigations;
— Section 4: Field tests;
— Section 5: Laboratory tests on samples;
— Section 6: Description of soils and rocks;
— Section 7: Reports and interpretation.
Section 1 deals with those matters of a technical, legal or environmental character that have usually to be taken into account in selecting the site (or in determining whether a selected site is suitable) and in preparing the design of the works.
Section 2 discusses general aspects and planning of ground investigations, including the influence of general conditions and ground conditions of the selection of methods of investigation. Sections 3, 4 and 5 discuss methods of ground investigation, sub-divided as follows:
Section 3 excavation, boring, sampling, probing and tests in boreholes; section 4: field tests; section 5: tests on samples. The division between sections 3 and 4 is somewhat arbitrary and has been based mainly on convenience in arranging the subject matter.
Section 6 deals with the terminology and systems recommended for use in describing and classifying soil and rock materials and rock masses. Section 7 deals with the preparation of field reports and final borehole logs, the interpretation of the data obtained from the investigation and the preparation of the final report. Users of this Code of Practice, particularly those of limited experience, are advised against referring to the methods of ground investigation in sections 3, 4 and 5 without studying the preliminary considerations in sections 1 and 2. It should be appreciated that the description of a method is only to be considered as a guide and should not be taken as mandatory. In this respect, it should be realized that development continues to take place involving changes in some of the methods. It may be noted that there is an imbalance of treatment between tests; in some cases more comprehensive treatment has been given to tests less frequently used. This is because many of the common tests are described extensively elsewhere (see BS 1377), whereas there is a paucity of reference to other tests.
The code has been drawn up in relation to conditions existing in the United Kingdom, but occasional reference is made to conditions overseas where this has appeared desirable.

A wide range of waterproofing systems considered suitable by manufacturers for concrete bridge decks have been laid under experimentally controlled conditions on a concrete slab at the Transport and Road Research Laboratory. Their performance was monitored over a three year period. Many of the systems, including some of those with a British Board of Agreement Roads and Bridges approval certificate for use, were found to be unsuitable or ineffective. Severe damage was often caused during the laying of the base course due to penetration of aggregate into the membrane. The use of sand carpet asphalt to protect membranes from the effects of base course aggregate overcame this problem, but the interface bond between membrane and sand carpet was weaker than that for base course road surfacing materials. Where membranes were punctured or leaked, water transmission was much greater where there was poor bond between the concrete and the membrane. Resinous primers gave a better bond to the concrete than their bituminous counterparts. The results showed that the test programme current during the period of the trial for approval certification of waterproofing membranes is inadequate as it does not cover the full range of conditions to which membranes are subjected. Tests are required to cover the effect of hot aggregate, bond, moisture content of the deck and waterproofing integrity over the ambient and asphalt temperature range. This will necessitate the development of improved waterproofing systems.
