With CGM grout material reinforcing steel corrosion can reduce

CGM high-strength non-shrinkage grouting material CGM high-strength non-shrinkage grouting material can reduce the reinforcement corrosion, there are three main principles: 1, the density is big, easy to infiltrate into the internal moisture in the air. 2, material skill do not contain chlorine ion, and the steel bar don't react. 3, the swelling, and steel combined more closely. When the reinforced concrete structure is one of the most widely used in international civil engineering structures, also most of the Chinese industrial and civil construction work of a structure. Reinforced concrete structure in a long period of time with the applied load and the natural environment, exist in the process of the scheme, construction, supervision and under the influence of uncertain factors, the use of function will be weakened gradually. Many of reinforced concrete structure at the time have been faced with data function degradation, reinforcement corrosion, short question, such as bearing capacity for the check without removal of the structure reconstruction, structure strengthening it becomes very important. Grouting reinforcement is a reinforcement technique of reinforced concrete structure commonly used over the years, because of the grouting material itself has good liquidity, micro swelling, strength increase fast, advanced interests reinforced bond strength, thus using more and more widely in the field of Chinese structure reinforcement engineering. This article for the reinforced concrete beam and slab of steel corrosion because of its strength and stiffness, through artificial imitation of reinforcement corrosion and then selects the grouting reinforcement method, steel corrosion on grouting material for concrete beam slab reinforcement effect. In three beams and 2 frames based on the test, the grouting material to reinforce the reinforcement corrosion damage characteristics of concrete beam and slab and the ultimate bearing capacity, stiffness, ductility and so on has carried on the research and analyze the influence of. Research results show that the selection of grouting material steel corrosion reinforced concrete beam and slab can obviously improve the test component of the bending function, advances its bearing capacity, increasing the structure stiffness and can delay the crack, deter crack expansion. Research conclusion of internship project partly grouting material the use of steel corrosion reinforcement concrete member is the primary reference value.
