In establishing JIS for chemical admixtures it is required to carry out quality control over admixtures (Air entraining and water reducing agents) now on the market. To that end we should: 1) Determine such specific values as will constitute the properties of admixtures to ensure production of high quality concrete: 2) Establish the method of testing the values of the properties. 3) Establish the standard for controlling the values of the properties. for the purpose of meeting the above mentioned requirements the writer picked up 2 lot each of various specimens of Chemical admixtures now on sale to test their specific gravity, solid content, PH value, foaming capability, relative surface tension and suspension value for the purpose of checking the variation of these specimens. the test was conducted successfully and I hope to explain in detail the testing method and publish the results later on.
