    Q. We're designing a concrete structure in Egypt, and I received test results for the aggregate to be used in the concrete. The report lists chloride and sulfate content, but I don't know how to evaluate these numbers because ASTM C 33, "Standard Specification for Concrete AggregatesConcrete Testing with Chloride & Sulphates Tests, Sussex,Chloride testing (and other chemical tests) of concrete can provide extremely useful information regarding the cause of defects or damage to concrete. The chemical concrete tests most frequently carried out are Chloride Test, Cement Content Test, Concrete Carbonation Test, Sulphate Test, Type of Cement Test and the Alkali Test.

  • METHOD OF TEST FOR THE SOUNDNESS OF AGGREGATES

    METHOD OF TEST FOR THE SOUNDNESS OF AGGREGATES BY USE OF SODIUM SULFATE A. SCOPE . The procedure to be followed when testing aggregates to determine their resistance to . disintegration by saturated solutions of sodium sulfate is described in this method. This method is a modification of AASHTO T 104. B. REFERENCESStandard Test Method for Acid-Soluble Chloride in Mortar,3.1 The amount of acid-soluble chloride in most hydraulic-cement systems is equal to the total amount of chloride in the system. However, some organic substances that may be introduced into mortar or concrete contain chloride that is initially acid-insoluble that can eventually ionize and thus become acid-soluble or water-soluble after a period of exposure in the very alkaline cement system.

  • Sulfate in concrete

    However, specifications for many constituent materials (aggregates, cement etc) place limits on the sulfate content. Also, in the UK, sulfate problems caused by naturally occurring aggregates are rare. Where an new source or material is to be considered or is suspected of containing sulfate, it should be assessed before being used.sulphate and chloride contents of concrete aggregates,sulphate contents aggregate and sand. Innovative solutions for the use of high sulfate content materials as aggregates for concrete Chaussadent T 1*, Colas J, Divet L,, aggregates have a high sulphate content of 347% of SO 3 in mass (60% anhydrite and 40%, A and sand with a content.

    It is a rapid test of aggregates: immersion of mortar bars in NaOH 1 M at 80 °C for 14 days used to quickly identify highly reactive aggregates or quasi non-reactive aggregates. ASTM C1293: “Test Method for Concrete Aggregates by Determination of Length Change of Concrete Due to Alkali-Silica Reaction”. It is a long-term confirmation testAnalysis of total chloride content in concrete ScienceDirect,Hence, the limits of total chloride content in concrete could be violated even though the limits of chloride content for mix ingredients are satisfied. Therefore, it can be stated that chloride limits of concrete ingredients and total concrete could not be consistent, especially with mix designs that have water cement ratios higher than 0.48.

    The aggregate crushing value test indicates the strength of aggregate which is the most essential property of coarse aggregate. The strength of coarse aggregates is assessed by aggregates crushing test. The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load.Concrete degradation Wikipedia,Concrete degradation may have various causes.Concrete can be damaged by fire, aggregate expansion, sea water effects, bacterial corrosion, calcium leaching, physical damage and chemical damage (from carbonatation, chlorides, sulfates and non-distilled water).This process adversely affects concrete exposed to these damaging stimuli.
