Study On The Property Of New Type Concrete Inorganic Protection Dose

The new concrete inorganic protective agent is a new type of protection material for concrete surface. It may infiltrate into the concrete internal, and obturate the surface of the concrete through reaction with the related material interior of the concrete. This new concrete inorganic protective agent can enhance the durability of both newly built and existing concrete structure.In allusion to validate the effect of this new concrete inorganic protective agent, this article has referred to a lot of datum. Upon the foundation of theoretical analysis, set a series of comparative tests on the durability of concrete. And I has chosen the corresponding raw material and the test instrument equipment as well as the testing method Applying different grades of concrete, C20 and C30, carry out tests on the durability of concrete such as freeze proof, impervious carbonization, compression-resi-stant, disjunction-resistant, absorbent, wear-resistant to concrete specimens which apply this new inorganic protective agent and to concrete specimens which not separately in the laboratory. And, the impervious ability may be enhanced a rank, carbonized ability has been enhanced above 20%, resistant to compression, the anti-booklet intensity may be enhanced 10%~15%, the anti-hydrogel cycle-index enhances above 25 times, the anti-salty frozen performance has been enhanced above one time. Through comparison and analysis of the test data, put forward that applying this new concrete inorganic protective agent in the concrete surface can improve muti-durability of concrete, and that the effect is visible especially for low strength concrete C20.In the experimental foundation, according to the concrete structure is the hole structure, through the theory and the electron microscope picture, has analyzed the new concretes inorganic protective agent from four aspects to the concretes improvement durable mechanism, and obtained the conclusion. The new concretes inorganic protective dose adjusts the concretes hole structure, and improves the function of concretes.In order to confirm the applying effect of this new inorganic protective agent furtherly, this new inorganic protective agent was applied in the reinforcement construction work of Wolonghe reservoir in Heilongjiang Province Ningan city. Uses for one year, it has been carried on the test in the scene, also proves that this new type of concrete inorganic protective agent has obvious improvement upon the durability of concrete.
