Description
Technical Field
The utility model belongs to the technical field of chloride ion measuring device's technique and specifically relates to a sand chloride ion content for building device for short-term test.
Background
According to the formulation of standards in the building industry, the standard GB 175-2007 general Portland cement (Portland cement) is formally implemented in the 6 th 1 st 2008, the rule that the content of chloride ions is required to be less than or equal to 0.06% is added in the standard, and therefore the attention to the detection of the chloride ions is increased in the building material industry. It is known that the chlorine ions in the sand affect the service life of the building material, and accelerate corrosion of the building material such as reinforcing steel bars in an environment where the chlorine ions are excessive. The search for a more convenient detection method is more beneficial to perfecting the standardized management of the building materials, and the attention on the chloride ion detection is increased in the building material industry. At present, the domestic building material industry mainly determines the chloride ions in cement, raw materials and concrete additives: ammonium thiocyanate volumetric method, phosphoric acid distillation-mercury salt titration method, potentiometric titration method, ion chromatography. The determination of chloride ions in GB/T76-2008 "Cement chemical analysis method" lists two methods: ammonium thiocyanate volumetric method (baseline method) and phosphoric acid distillation-mercury salt titration method (surrogate method); in GB/T8077-2012, the homogeneity test method of the concrete admixture adopts a potentiometric titration method and an ion chromatography method; EN 196-2: 2005(1SO 29581-1) ammonium thiocyanate volumetric method. The several methods for measuring chloride ions have respective application ranges, advantages and disadvantages and operational points suitable for the method.
In the market, the chloride ion detection is mainly performed by laboratory methods such as instrument and equipment detection, the rapid detection of the building material raw materials in the production place or in the transportation process is not implemented, and the national standard preparation and repair has stricter requirements on the building materials. According to the current supply way of the building material sand, the sand is mostly transported in bulk. Therefore, the materials need to be subjected to primary screening inspection, so that the transportation inspection cost of unqualified materials is reduced, and the quality of building materials is ensured.
