  1. The new high effective water - reducing agent act - fdn has characteristic of reactivity, it ca n ' t dissolve in water but do in alklia. in the concrete, it decompounds slowly and gives out sulfonate group which has dispersity, this can make the high effective water - reducing agent available for a long time, therefore it can reduce slump loss

    研製的新型高效減水劑act - fdn ,具有反應性的特點,不溶於水但溶於,在這樣的性環境下可以緩慢分解釋放出具有分散性能的陰離子磺基,使高效減水劑能夠持久發揮作用,從而達到了降低坍落損失的目的。
  2. The liquid - gas method is improved based on the above methods, overcoming the defects of gbj82 - 85. using the liquid - gas method, permeability condition of concrete can be tested and indicated quickly, efficiently, and the influences on concrete of alkali - aggregate reaction, sulfate attack, carbonization, steel rust, freeze and thaw can be inflected indirectly. it is significant on the research and monitor on the durability of concrete

    溶液氣壓法是在上述方法之上進行改進提高的,克服了國標gbj82 - 85方法中的許多不足之處,能夠多角、快速、高效、真實、準確地再現現場的滲透情況,並且能間接反映-骨料反應、鋼筋銹蝕、碳化、硫鹽侵蝕及凍融破壞的影響,對耐久性的監測與研究具有重要意義。
  3. For concrete structure in the practical engineering, the non - mechanics damages, such as alkali - aggregate reaction, sulfate attack, carbonization, steel rust, freeze and thaw, and so on, are unavoidable due to the exist of erosive media. the deterioration form of mono or multi - factor influences on the concrete property of construction and durability greatly, and shortens the service life of the concrete to a large extent. permeability of concrete is the most important factor for these non - mechanics damages, so the permeability test of concrete is the normal and required item to study the durability of concrete

    實際工程中的結構,因侵蝕性介質的存在而使非力學破壞行為無處不在,這些非力學破壞行為包括集料反應、硫鹽侵蝕、碳化、鋼筋銹蝕、凍融等,單一的破壞形式或多形式的復合破壞作用對結構性能及耐久性能均有著較為嚴重的影響,在很大程上縮短了建築物的服役年限,而這些非力學破壞在很大程上取決于其滲透性,所以測試滲透性能是研究判斷耐久性的常規必測項目。
  4. Standard test method for length change of concrete due to alkali - carbonate rock reaction

    由於金屬碳鹽礦石反應引起變化的標準試驗方法
