PREPARATION METHOD OF ORGANIC FERTILIZER, YELLOW SOIL GYPSUM CEMENT MORTAR AND YELLOW SOIL BRICK USING YELLOW SOIL, WASTE GYPSUM AND EXCRETION

摘要

PURPOSE: A method for preparing an organic fertilizer, a yellow soil gypsum cement mortar and a yellow soil brick by using yellow soil, waste gypsum and excretion is provided, to recycle the waste and to use the cement mortar and brick as a material for construction having excellent warming and waterproofing property. CONSTITUTION: The method comprises the steps of mixing 40-45 wt% of yellow soil, 40-45 wt% of waste gypsum and 15-20 wt% of excretion; boiling the mixture for several times by using the incineration heat; sorting the obtained one into microparticle and granule by size; and adding the sorted one to the fertilizer-dissolved water to prepare the organic fertilizer, or adding the sorted one to the gypsum powder to prepare a white fertilizer. The method comprises the steps of mixing waste gypsum and yellow soil; boiling the mixture; sorting the obtained one into microparticle and granule by size; and mixing the microparticle with yellow soil and water to prepare the yellow soil gypsum cement mortar.
