PURPOSE : A ground resistance reducing agent composition is provided to improve mechanical bonding by the affinity with soil by using a natural mineral-based material and to prevent the pollution of soil and water by the micro-granular structure of excellent water permeability.CONSTITUTION : A ground resistance reducing agent composition comprises 27~37 weight%% of cokes; 12~32 weight%% of anthracite powder; 9~25 weight of graphite; and 15~30 weight%% of Portland cement. The cokes and the anthracite powder have a particle size of 0.01 mm ~ 3 mm, and the graphite has a particle size of 70~130 mesh. The cokes is a porous solid comprising carbon, ash and volatile components, and has a plurality of pores and channels in the structure.COPYRIGHT KIPO 2010 |
