Experimental Evaluation of Behaviors of the Soft Sand ‘RHACLSMC’ under Temperature Variations and the Natural Environment Conditions

Abstract

Numerical Simulation of the Composite Sand Ground ‘RHACLSMC’ Strains under the Groundwater level and Natural Condition variations measured behaviors of sand under displacement, and natural condition variation. The composite sand ‘RHACLSMC’ with material mixtures ‘rice husk ash’ of 4%; ‘lime’ of 8%; ‘sawdust’ of 8%; ‘mangrove charcoal’ of 4%; under Temperature Variations from 310C to 350C and the Natural Environment Conditions consideration. The research results show the decreasing of temperature and changing of the natural environment conditions (wind speed, air moisture, dew-point, cloud density, air quality, and other factors), which result in the decrease of sample volume, weight, water content, and sizes; whereas compared with the increasing of time. Moreover, the colors changed remarkably in the soft sand sample according to water content, temperature, weight, and time increase. On the other hand, the results of the Numerical simulation presented the Mobilized Shear Strength, total Volumetric Strains, and the veritcal displacement are small. So these relative research results contribute to the soft sand ‘RHACLSMC’ ground improvement technology with material mixtures for references for design, building, and construction in Geology engineering in the future.
