Impact of RBI Grade-81 on expansive soil strength characteristics
In this research, an attempt is made to understand the impact on strength characteristics of expansive soil treated with Road Building International Grade-81 (RBI-Grade-81) stabilizer. This stabilizer has a wide response spectrum range. A broad range of studies, such as Atterberg limit, Compaction, Unconfined compressive strength (UCS), and California bearing ratio (CBR) measures, are demonstrated on expansive soil and it is treated with percentages varying between 2 and 10% of RBI-Grade-81. Due to the creation of new cement materials, which is apparent in the SEM research micrographs, the improvement in intensity is achieved. The results suggest that considered stabiliser is effective in enhancing the engineering properties of expansive soil. � 2019 Elsevier Ltd. All rights reserved.
Effect of RBI Grade 81 on strength characteristics of Expansive soil
Expansive soils which are generally termed as problematic soils cause swelling and shrinkage resulting in significant damage to the structures constructed on them. In this study an attempt is made to know the effect of Road Building International Grade 81 (RBI Grade 81) on strength characteristics of expansive soil. RBI Grade 81 has a wide range of response spectrum. Response spectrum is the range of soils for which a particular stabilizer can be used. A wide range of tests such as Atterberg limits, Compaction, Unconfined compressive strength and California bearing ratio were conducted on expansive soil and expansive soil treated with various percentages of RBI Grade 81. The results indicate that RBI Grade 81 is effective in improving engineering properties of expansive soil. � The Electrochemical Society
