STRENGTH PRIORITIES OF CHEMICALLY SOLIDIFIED SOILS

Injection of chemical grout is a valid means of strengthening sandy soils. Submission of valid strength data is recommended as a condition for use of any particular grout material. Pertinent data should include the specimen size, method of preparation, age, curing environment, and method of test. Because of its ease, speed, and economy, plus providing shear values, the unconfined compression test is preferred. In addition to the chemical grout itself, factors which significantly affect strength, include curing environment, rate of drying, and method and rate of loading. Of particular importance is strength of a specimen under continuous loading, which is considerably less than its ultimate strength under rapid loading. Of less importance are soil grain size, shape, moisture and density. Presented are results of over 2500 laboratory samples utilizing 12 mixes of eight different grouts. They were correlated with about 100 field samples.
