LOESS COMPOSITION FOR ENGINEERING/CONSTRUCTION AND A MANUFACTURING METHOD THEREOF CAPABLE OF INCREASING DURABILITY OF LOESS BLOCK AND LOESS ROAD

摘要

PURPOSE: A loess composition for engineering/construction and a manufacturing method thereof are provided to improve physical property without deviation of physical property by assorting granite soil by size.;CONSTITUTION: A loess composition for engineering/construction comprises 50-80 weight% of granite soil, 5-20 weight% of loess powder having particle size of 2,000-2,500 mesh, 5-20 weight% of silica having particle size of 150-200 mesh, and 10-20 weight% of inorganic binder. A manufacturing method of loess composition for engineering/construction comprises next steps: heat treating granite soil at 200-400 deg. Celsius and pyrolyzing, extinction processing, and drying the organic compound; assorting the heat-treated granite soil with a sieve having mesh size of 2-13mm in order to collect sieve passed granite soil; mixing 50-80 weight% of collected granite soil, 5-20 weight% of loess powder having 2,000-2,500 mesh, 5-20 weight% of silica having mesh size of 150-200, and 10-20 weight% of inorganic binder; and packing the mixed composition.;COPYRIGHT KIPO 2012
