Adverse conditions such as ground contamination, high temperature, humidity, fluctuating temperature and relative humidity can reduce the life span of the structure, says A.R.Santhakumar Determinant: A major factor influencing the service life of concrete structures is the nature of exposure conditions. Generally Reinforced concrete apartment buildings in India lasts only for 30 to 50 years compared to the expectation of 70 to 80 years. The short life span is an economic burden for not only owners and residents but to the nation as a whole. A recent Japanese report urged housing industry in that country to adopt, as a goal, an average life span of 200 years. This will enable reducing the wastes during demolition, energy conservation, and harmony with environment, resistance to disasters like earthquakes and cyclones and achieving good behaviour by regular and easy maintenance. The major factor influencing long-term service life of concrete structures is the nature of exposure conditions and environment to which concrete is subjected to especially soon after casting and subsequent early ages. It is to be noted that while the manufacture of concrete is under the control of the engineer environment during early age is a factor beyond human control and not accounted for either during construction or during design. Adverse conditions such as ground contamination, high temperature, humidity, fluctuating temperature and relative humidity can cause damage and reduce the life span of the structure. Reinforcement The early age environment is the most critical factor which influences concrete degradation affecting long term serviceability of RCC apartment structures. Severe exposure conditions such as those present in coastal areas are known to indicate deterioration, cracking and reinforcement corrosion. While reinforcing steel is protected by design by ensuring adequate cover, there are several electrical, plumbing and other steel items which are embedded in the cover region of concrete as inserts not knowing the damage they can cause for long-term serviceability. It is indeed, the interaction between concrete, steel insert and environment that dictate the material performance and hence the life of the structure itself. The exposure conditions in the coastal areas and especially on the east coast where Chennai is located are recognised as some of the most aggressive climatic conditions which pose severe challenges to the design and construction engineer. In this type of exposure, the quality and extent of water curing, and the subsequent interaction between concrete and environment can often control and dictate concrete material performance resulting in premature deterioration and low durable service life of concrete structures. The material composition and shape must be sustainable to reduce environmental pollution and conserve material and energy resources. However, the sad fact is that in spite of the excellent strength and durability properties concrete materials deteriorate at an unacceptable rate when they are exposed to real environment at locations where we have ignored the Acetylic concepts of corrosion in inserts and fixtures which normally happens in the corner region of concrete. Recent studies have shown that environmental effect reduces the strength and stiffness of structure at different rates. The performance is related to deformation / deterioration aspects not necessarily under control of the designer but largely in the hands of the user. Apartment housing nowadays insists that on both shared and private spaces the RCC frame is the skeleton which bears the load and accounts for service life and stability of structure. To extend service life all materials which are used as inserts or allotments on the RCC frames should be barrage (non corrosive) though such materials may be costly at installation but the life cost will be less. The concepts of uses of stainless steel inserts for the pipes, electrical and plumbing system reduces the need for repair and extends the life of not only services but the entire structure. Mild steel holding fast frame clamps embedded in concrete tend to corrode and disrupt the whole RCC frame itself. When the gab corrode, products of corrosion will occupy 5
