Acronym corrosion resistant sulfate preservatives characteristics; concrete corrosion resistant sulfate preservatives, hereinafter referred to as "concrete preservative" is a new generation of reinforced concrete to prevent corrosion of a new product, it broke through the traditional concept of reinforced concrete corrosion, creating the use of new anti-corrosion additive method, a fundamental solution to the many problems and limitations of traditional methods of corrosion. Use concrete sulfate resistance preservatives can make concrete with salt ionic erosion, freezing and thawing damage the good performance and high resistance to infiltration. Especially suitable for both concrete building requirements and the requirements of impermeability corrosion engineering. The product can also be incorporated into the concrete to reduce shrinkage, ease of mass concrete construction. Concrete preservatives, easy to apply and does not require special construction technology. At the same time further utilization of this method for preserving industrial waste - fly ash, with green meaning. By adding an appropriate amount of preservative in the ordinary portland cement (to replace part of cement fly ash or slag), and made a new cementitious materials, products comply with People's Republic of China building materials industry standard JC / T1011-2006 the indicators. The ability of anti-sulfate binder has exceeded the "Railway concrete and masonry construction norms" Appendix AS Advanced sulphate resisting cement thirteen prescribed level. Durability and workability of concrete is greatly improved. Using concrete preservatives production of reinforced concrete with a corrosion-resistant, anti-freezing and thawing, high strength, impermeable, shrinkage, less water is high excellent performance. Corrosion resistance of concrete sulfate preservative use; the use of preservatives and traditional anti-corrosion method (coated technology, increase the protective layer, sulphate resisting cement, high-strength concrete) compared to the corrosion resistance, durability of concrete, reinforced protection of the environment by limiting construction, construction and maintenance processes have advantages. Its economic costs, the latter protection costs are relatively low. Description: The main features of saline soil is soil containing salts, especially soluble salt, highway bridges and culverts and structures it has significant corrosion, and basic structures and underground facilities constitute a more severe corrosive environments affect its durability and safety. Therefore, the durability of concrete in saline soil area has become a key issue in the region and highway bridge structures affect normal operation. In China's western region, due to the phenomenon of concrete structures damaged by corrosion caused quite common. On the one hand, the rapid economic development of the western bring increased traffic, the road transport is particularly poor, need a lot of road construction; on the other hand departments annually spend a lot of manpower and material resources to govern, but the effect is not ideal, resulting in huge economic loss, making road service capacity of saline soils is seriously lagging behind in non-saline soil area. Soil, groundwater, seawater, decaying organic matter and industrial waste water contains large amounts of sulfate, sulfate ions penetrate the concrete reacts and hydration products of cement to produce corrosion products has expanded in nature, resulting in stress within the concrete When the internal stress exceeds the tensile strength of concrete, it is the concrete cracking, peeling and so on, so that the concrete result of the loss of strength and adhesion properties of the destruction occurred, and lead to reduced life durability of concrete structures, and therefore in some areas , anti-sulfate preservative essential. Concrete preservatives, anti-corrosion mechanism of sulfate resistance of concrete sulfate corrosion preservative scope and content; this product can be widely applied to coal-bearing formation and magnesium sulfate, sulfide ore formation, gypsum formations, silt carbon layer , reinforced concrete structure in the saline soil area, salt lakes, coastal salt, coastal ports, water infiltration areas and other adverse geological region and marine waters. 1, suitable for coastal, harbor, salt, saline soil, road sulfide-containing or gypsum formations and other natural areas, tunnels, bridges and other industrial and civil infrastructure construction; the sewerage system in the culvert pipe; underground pipe network and other chemicals contaminated areas. Where such areas contained in the sulfate concentration in the 300 ~ 15000mg / L range can use the agent, in the 10000 ~ 15000mg / L range using this agent, sulfate resistance of which is much higher than sulphate resisting cement. 2, the product of the content of 6-8% of cementitious material. 3, cement shall meet the requirements of the national GB175. 4, the proposed design of concrete mix should be mixed with appropriate amount of fly ash, ground slag. Corrosion resistance of concrete sulfate preservative works; concrete preservatives works: not through simple water reducer or minerals added in portland cement admixture improve the density of concrete, but can invade the lower concrete sulfate ion concentration and pore refining pores and inhibit the precipitation of calcium hydroxide from cement velocity. To achieve anti-form gypsum and ettringite crystal restrain its expanded role in the destruction, then play delay the destruction of see concrete sulfate attack speed, the product can effectively prevent the expansion ettringite crystal damage, gypsum crystal expansion damage, magnesium salt crystal damage, thaumasite crystal damage, thereby improving durability of concrete structures.
