Research On Anti-Leakage And Anti-Split Performance Of Concrete

Due to the stress which has been formed from the shrinkage in concrete, for the brittle concrete structure, when it is restrained by the inner or outer stress, it is likely to crack. Thus it can seriously affect the strength and durability of concrete structure. This paper introduces a new admixture ZSFS1000, studying the workability, mechanical properties and durability of the admixture concrete.Workability testing shows that, concrete reduce bleeding with the addition of ZSFS1000 which can also be promoting early condensate, improving the workability of the concrete.Mechanical property testing indicates that compared with the blank concrete the value of compressive strength of the concrete adding ZSFS1000 on the 3rd day,the 7th day and 28th day has also been enhanced.Durability research shows: the admixture concrete effectively improve the penetration of chloride ion concrete, significantly improving the impermeability grade of concrete, extending early crack concrete. ZSFS1000 reduce the crack width and significantly reduce shrinkage cracking; improve anti-carbonation, anti - sulfate and frost resistance of concrete. Through porosity tests, ZSFS1000 can improve the concrete pore structure and compactness.
