【文章內(nèi)容簡介】 f reinforced concrete structures is necessary. that affect the mechanism of reinforced concreteMany factors have an impact resistance of reinforced in the water area more than 50 chemicals in the corrosive elements, water, work and play in which the regulatory concrete model to obtain a related approach is a practical understanding of multifactor , for a single factor, many of the results only take into account the effect of concrete carbonation, carbonation thickness can be expressed using the following formula:Can be written as: D (t) = K t (1)Where D (t), K and t are the thickness, the speed factor and carbonization time.So far, although many models have been applied to the reinforcement of the fracture, fatigue failure, but has not accepted the conclusions of all general, to reduce the resistance of reinforced concrete reinforcement geometry variables, the surrounding environment as well as resistance to change over time and so , resistance to change is reinforced concrete, a random function or set of materials, processes and structure of variable concrete carbonation in the air is called in and is plex and CO2 in the air as well as the basic material of reinforced concrete and in the slow in the air fully dense protective layer of reinforced concrete will take decades, but the nonpacting concrete carbonation as long as several the thin material with high content of carbon, the strength of reinforced concrete will drop and the structure in the carbonization process will speed up the narrow can cause lowering of alkalinity and steel surface of the steel reinforcement corrosion of iron is steadily losing its electronic and then in water, and then under the conditions in the aerobic react with , the consumption of time many times a lot of erosion allows the production of reinforced concrete protective layer cracks, and along the direction of Jiangdi Gangjin the bond between steel bars and concrete strength, reinforced concrete structure, resulting in the loss of carrying studies suggest that the most serious corrosion of nonreinforced carbon protective layer 15mm the other hand, due to imperfections on the surface and the cracks in the concrete, so that corrosion may be ahead of the start time, and the corrosion rate may be greatly the steel stress is less than the yield point, the damage rate is when the steel stress exceeds the yield point, the damage rate will increase several latter is known as stress fracture, which is brittle and dangerous of steel reinforcement will reduce the pressure area, destroy the structure of bond strength and reduced of the air and all of reinforced concrete liquid will have a huge can cause corrosion of reinforced concrete, concrete cover thickness reduction, and ultimately accelerate the corrosion of the structure bear live loads, fatigue of reinforced concrete structures destroyed, causing the ultimate strength and stiffness of the decline, Erju and expanded to produce fa
