EFFECTIVENESS OF SUGARCANE STRAW ASH AND PULVERIZED USED PAPER FOR STABILIZATION OF VERTISOLS SOIL
Journal Title: Engineering and Technology Journal - Year 2023, Vol 8, Issue 05
Abstract
In the discipline of civil engineering, the foundation plays a crucial role in supporting and containing loads of complete structures. Therefore, a foundation needs to be strong enough to increase any structure's useful life. The soil has a direct impact on the structure's foundation. Vertisols soil is soil with unstable and weak soil that needs to be stabilized to make the soil suitable for construction purposes. The study is to determine the effectiveness of the pulverized used paper and sugarcane straw ash as stabilizers of vertisols soil in San Isidro, Nueva Ecija. Natural soil was classified as A-7-6 of AASTHO classification system and CH as group name classified by USCS classification system, indicates that the soil is high in clay. The index properties of the natural soil showed that it is poor and weak soil that is not applicable for engineering purposes. Liquid limit and plasticity index values of 60% and 35%, respectively, suggested that the soil is in high plasticity. There is a gradual decrease in the plasticity index to a value of 25% at 15% SCSA+PUP as compared to natural vertisols soil with 35%, this indicates that the soil is progressively stabilizing. In addition, there are increases in the compaction parameters and CBR value of 14.0283 kN/m3 and 5.47 at 100% MDD compared to natural vertisols soil with values of 13.69476 kN/m3 and 4.83 at 100% MDD, respectively. But these values fall from the requirement suggested of sub-base coarse, however, there are considerable changes in the vertisols soil using SCSA and PUP. This research aimed to determine the effectiveness of SCSA and PUP in stabilizing the vertisols soil
