POROUS BLOCK FOR STABILIZING SLOPE

摘要

PURPOSE: A porous block for stabilizing the slope is provided, which shows pH near to neutrality, enables plants to be grown up in the slope, is environmental-friendly and stabilizes the slope. CONSTITUTION: The porous block is prepared by heating the naturally dried yellow soil to 1,000 deg.C to sinter it, cooling the sintered rapidly to activate it, and pulverizing the activated one; mixing the obtained yellow soil with calcium oxide to prepare a yellow soil glue; mixing the aggregate with a size of 20-25 mm, 15-20 mm or 5-13 mm with the yellow soil glue in the ratio of 3-5 : 1 by weight; adding 25-32 wt% of water and 0.5-2 wt% of a mixing agent (a highly efficient water reducing agent and a superplasticizer); and vibration compressing the obtained mixture. Preferably the aggregate is rubble or gravel.
