TEST SOIL FOR COMPRESSIVE STRENGTH EVALUATION AND TEST METHOD FOR EVALUATING COMPRESSIVE STRENGTH USING TEST SOIL
PROBLEM TO BE SOLVED: To provide a new test soil capable of appropriately evaluating the compressive strength of a cement based solidifying material using volcanic cohesive soil as an object soil, and a test method for evaluating compressive strength using the test soil.SOLUTION: The test soil for evaluating the compressive strength of a cement based solidifying material is obtained by mixing a dry clay having a composition of SiOof 47.0-57.0 mass%, AlOof 15.0-19.0 mass% and FeOof 3.8-8.2 mass% and having a moisture content of 5% or less and an allophane having a composition of SiOof 33.0-41.0 mass%, AlOof 33.0-41.0 mass% and FeOof 1.7-4.3 mass% at a proportion of 90:10-70:30 by a mass ratio. The test method for evaluating the compressive strength of the cement based solidifying material comprises mixing the cement based solidifying material with water to form slurry; and mixing the slurry with the test soil for evaluating the compressive strength of the cement based solidifying material to evaluate the compressive strength.
【課題】火山灰質粘性土等を対象土とするセメント系固化材の圧縮強度を適正に評価することができる新規な試験土及び当該試験土を用いた圧縮強度評価試験方法を提供する。【解決手段】セメント系固化材の圧縮強度評価用試験土は、ＳｉＯ２が４７．０〜５７．０質量％、Ａｌ２Ｏ３が１５．０〜１９．０質量％及びＦｅ２Ｏ３が３．８〜８．２質量％の組成を有し含水比が５％以下である乾燥粘土と、ＳｉＯ２が３３．０〜４１．０質量％、Ａｌ２Ｏ３が３３．０〜４１．０質量％及びＦｅ２Ｏ３が１．７〜４．３質量％の組成有するアロフェンとを、質量比で９０：１０〜７０：３０の割合で配合してなる。また、セメント系固化材の圧縮強度評価試験方法は、セメント系固化材に水を混合してスラリーとし、該スラリーに前記セメント系固化材の圧縮強度評価用試験土を配合して圧縮強度を評価する。【選択図】図３
