PURPOSE : An inorganic composite in a non-cement system for soil pavement is provided to maintain an intrinsic property of soil pavement, to have excellent compression strength, and to prevent the elution of heavy metals by using a lasting type alkali activator which has granulated blast furnace slag powder and natural acid clay.CONSTITUTION : An inorganic composite in a non-cement system for soil pavement comprises 100.0 of granulated blast furnace slag and 5-20 parts by weight of a lasting type alkali activator. The lasting alkali activator comprises 1, 000 parts by weight of natural acid clay, 50 parts by weight of natural anhydrous gypsum, 5-20 parts by weight of slaked lime, 5-10 parts by weight of sodium hydroxide, 5-10 parts by weight of potassium silicate and 0.5-2.5 parts by weight of calcium stearate. A production method of the lasting alkali activator includes the following steps; the first pulverized product is produced by grinding a mixture of the natural acid clay and the anhydrous gypsum with the weight ratio of 100 : 50 into a size of 7, 000-8, 000 cm^2/g; the second pulverized product is produced by grinding the sodium hydroxide, the potassium silicate, the slaked lime and calcium stearate into 3, 000-4, 000cm^2/g; and the first pulverized product and the second pulverized product is mixed for 10-20 minutes.[Reference numerals] (AA) Generation of a first pulverized product(mixing and pulverizing natural acid clay/natural anhydrous gypsum); (BB) Generation of a second pulverized product(mixing and pulverizing sodium hydroxide/potassium silicate/slaked lime/calcium stearate); (CC) Mixture of the first pulverized product/the second pulverized product; (DD) Production of a continuous alkali magnetic material; (EE) Mixing of the continuous alkali magnetic material/granulated blast furnace slag powder; (FF) Inorganic composite compositionCOPYRIGHT KIPO 2013 |
