Experimental study on effect of acetic acid and carbonic acid on clay’s geotechnical behaviors;
乙酸和碳酸对粘土土工性状影响的试验
The source,existing form and equilibrium of carbonic acid in natural water are presented in this article,which points out that alkalinity is determined by double indicator that indicates purply at the first terminal point,while at the second terminal point should use methyl red-bromocresol green mixed indicator.
