Nothing lasts forever! Concrete protection and repair in building construction becomes necessary because of fails caused by:.
To support this era of rapid growth in urbanization and economic and development of Cambodia, Dynamic Chemicals Co. Download PDF. Example of concrete structures need to be repaired:. The Protection coating and impregnations, utilizing the latest German technologies, extend the life of structures by minimizing the ingress of moisture to the concrete, thereby preventing salts from affecting the steel reinforcement.
Repair Protection and Waterproofing of Concrete Structures Third edition By P H Perkins
Building Maintenance Technology pp Cite as. Reinforced concrete is generally a very durable structural material and very little repair work is usually needed. However, its durability can be affected by a variety of causes, including those of design and construction faults, use of inferior materials and exposure to aggressive environments. The need for a repair is primarily dictated by the severity of the deterioration as determined from the diagnosis. Good workmanship is essential if anything more than just a cosmetic treatment to the concrete is required.
Since the publication of the Second Edition of this book in , the need to carry out extensive repairs to reinforced concrete structures has continued. Most of these structures were originally expected to have a life span of 80— years and this premature deterioration has caused serious concern. In this country considerable publicity has been given in the technical press to major repair work on road bridge structures, particularly on major trunk roads and motorways. While structural design, including specification, varies to some extent from one country to another, the materials used—namely Portland cement, aggregates, steel reinforcement and mixing water—are essentially similar. The main cause underlying this deterioration is also basically similar, namely the corrosion of the steel reinforcement. Repair methods show somewhat wider differences.

Kendall, Kevin, and Steven F. Concrete structures located in aggressive environments where high temperatures and high chloride levels exist in Both natural soils and water are subject to premature deterioration from corrosion of the reinforcement. Traditional methods of corrosion protection, such as concrete admixtures and passive barrier systems, may not be sufficient to provide the level of corrosion control needed for the intended design life. As a solution to this problem the use of cathodic protection or cathodic prevention as it is called at the time of construction is proposed. Although cathodic protection has been used as a rehabilitation method on existing salt-contaminated concrete structures for over 20 years, its application to new reinforced concrete structures is relatively new. It has been shown, however, that the cathodic current density necessary to maintain a passive layer on the reinforcing steel before the concrete is contaminated with chlorides is relatively low and that the chloride ion tends to migrate towards the anode. The application of cathodic prevention during new construction can have lower initial cost than conventional methods and significant long-term benefits.
A wealth of recent research into the continued deterioration of reinforced concrete structures has led to a review of methods of investigation and repair techniques. This thoroughly revised and updated new edition brings together the fundamental aspects of this world wide problem and offers advice on how investigations, diagnosis and consequent remedial work should be carried out.

- Она подошла вплотную к окну. Бринкерхофф почувствовал, как его тело покрывается холодным. Мидж продолжала читать.
Вряд ли он позволил бы ТРАНСТЕКСТУ простаивать целый уик-энд. - Хорошо, хорошо. - Мидж вздохнула. - Я ошиблась. - Она сдвинула брови, задумавшись, почему ТРАНСТЕКСТ за весь день не взломал ни единого шифра.

- Она просто так себя ведет. Мидж посмотрела на него с удивлением. - Я вовсе не имела в виду твою жену. - Она невинно захлопала ресницами. - Я имела в виду Кармен. - Это имя она произнесла с нарочитым пуэрто-риканским акцентом.
