TL;DR: In this paper, the authors have identified the most suitable method of mix design for RAC, from amongst the available conventional methods for mix design, and an empirical relation is suggested to modify the influencing parameter.

TL;DR: In this article, the effects of soil-structure interaction (SSI) on the seismic response of short span bridges are investigated. But the authors focus on pier behavior, since piers together with the abutments are the most critical elements in securing the integrity of bridge superstructures during earthquakes.

TL;DR: In this paper, a study was conducted to determine the effects of using kiln dust (a pozzolonic waste byproduct of cement manufacture) as a cost reducing additive in blended cements.

TL;DR: Instrumented drop weight impact and compression after impact test methods were used to assess the impact performance and damage tolerance of firm-stacked, woven carbon fiber reinforced PEEK and woven carbon fibre-reinforced PPS composite systems as mentioned in this paper.

TL;DR: In this article, the stabilising effect of locally produced lime on three lateritic soils from Kumasi in Ghana was investigated and the effect of variation in lime on Atterberg limits, moisture density relationship and strength characteristics was considered.

TL;DR: In this article, the effects of compaction pressure (moulding pressure), simulated rainfall, and cement content on the durability of soil-cement bricks have been investigated, and the results show that the resistance of the bricks to erosion by raindrops was enhanced by increase in compaction pressures and cements content.

TL;DR: A review of current research topics in the UK on environmentally induced or assisted cracking is given with particular emphasis on how these research interests are related to current industrial applications as mentioned in this paper, and some particularly topical items are described in greater detail including corrosion fatigue of offshore structural materials, pipeline cracking, high strength fasteners and deaerator cracking.

TL;DR: The ICOLD Committee on Materials for Concrete Dams as discussed by the authors conducted a detailed international survey to establish the prime cause of dam and/or reservoir deterioration and found that 11% of all cases at concrete dams had incurred some form of attack from the environment.

TL;DR: In this paper, an evaluation of materials used in kuwait for the construction of external walls and roofs of buildings was carried out, in the form of a questionnaire, was based on eleven performance criteria (eg. serviceability, durability etc.).

TL;DR: In this article, the fundamental requirements for the physical, chemical and electrochemical stability of repairs to reinforced concrete structures are compared with data typically available for proprietary products, and suggestions are made for a test approach to improve the evaluation of repair materials and to enable mixes to be designed for specific applications.

TL;DR: In this paper, a test method is described to measure the bond/tensile strength of brickwork joints, and hence evaluate the compatibility of the associated materials, which can be incorporated into single skin brick walls, to allow the study of in-situ, in-service durability characteristics.

TL;DR: The most common form of adhesives is the overlap in which the adherends may be plain or tapered to aid the smooth transfer of the loads through the structure, thus minimizing the stress concentrations and maximising the joint strength.

TL;DR: A number of reactive adhesives on formaldehyde base have been developed for use with timber-type products and polymer dispersions produced during and since the 1950s are widely used by the building trade today.

TL;DR: In this paper, the influence of a geotextile inclusion on bearing capacity of a two-layer subsoil consisting of a layer of sand fill on the surface of soft clay has been investigated.

TL;DR: In this article, the effect of surge pressures on the survivability and damage resistance of 0.15 m diameter plastic pipe (GRP and uPVC) was investigated. And the tests demonstrated that plastic pipes can quite safely take the place of metal pipes provided care is taken over the selection of plastic type and method of construction.

TL;DR: In this article, the current situation relating to European Cement Standards is described with particular reference to filler cements, and the present version of ENV197 just failed European voting acceptance because it was considered too restrictive.

TL;DR: In this paper, alternative types of coatings which remove water, penetrate and stabilize rust, possess no converters and are used as thin primers or thick one-layer coatings are presented.

TL;DR: The structural bonding of aluminium components in load-bearing civil engineering applications has been the subject of an extensive research program carried out by TNO (Dutch Organisation for Applied Scientific Research), 8 industrial companies and the Ministry of Commerce.

TL;DR: In this article, the authors identify some of the conditions which can contribute to adhesion failure in particular the effect of environmental conditions during application and curing, the chemical changes which occur in the paint as it ages in the container, and the effects of sunlight as the material cures.

TL;DR: Sekril as discussed by the authors is a synthetic organic fiber developed some five years ago by Courtaulds Research specifically for cement reinforcement and is available in a wide variety of filament dimensions in order to satisfy the requirements of process technologies and performance demands.

TL;DR: In this article, a method using end moments and deflections as primary quantities is presented as an alternative procedure to the conventional slope-deflection method, referred to as the moment -or curvature-deflector method.

TL;DR: In this article, the variation of the moisture content for those timber species commonly used in Hong Kong with relative humidity of the environment is reported by carrying out an 'in-situ' test as well as a precise measurement in an environmental chamber.

TL;DR: In this article, an automated production technique for continuous fiber reinforced plastic walkways is introduced, demonstrating how this technique could allow for the design and manufacture of walkways of increased geometrical complexity with significantly improved short-term mechanical performance.

TL;DR: In this paper, a preoxidation treatment for stainless steel which produces an improvement in corrosion resistance is described, and the oxide which forms on the untreated and pretreated steel is characterised using X-ray diffraction, Auger spectroscopy and Secondary Ion Mass Spectroscopy.

TL;DR: In this paper, the bonding of single skin GRC membranes to frames of a variety of materials is discussed, together with details of jointing, anchoring, and advantages offered.
