Astm c 14 standard test method for potential alkali. Retain the other three quarters of the sample for further testing if desired.
A potentially deleterious degree of alkali X1. Do not use the results of tests by this test method as the sole basis for acceptance or rejection for sources with regard to ASR. Essentially, ASR distress is caused when aggregates awtm unstable silica minerals react with cements having high alkali content, to form a gel. Please help us to share our service with your friends.
Please fill this form, we will try to respond as soon as possible. Current edition approved Aug.
ASR distress is identified by map-cracking, which is a random pattern of cracks. Unless otherwise indicated, all reagents shall conform to the specifications of the Committee on Analytical Reagents of the American Chemical Society, where such specifications are available. Record the total amount of time during which the vacuum is applied as the filtration time; make every effort to achieve an equal filtration time for all samples in a set, by uniformity of procedure in the assembly of the filtration apparatus and the packing of the solids in the crucible.
