    摘要: A soil or ground reinforcing material consisting of Al--Fe oxides mixture the main contents of which are iron oxide made from fine iron oxide powder byproduced in steel production and Aluminum oxide made from red mud by-produced in Aluminum smeltering and lime added therein is mixed into a soil containing crushed stones, natural soil, etc., and further Titanium oxide is mixed into the above soil or ground reinforcing material to make Al--Fe--Ti oxides mixture in which lime is added and mix this material into a soil or ground containing crushed stones, natural soil, etc. to enhance the strength and viscoelasticity thereof. The content of the Titanium oxide in the soil or ground reinforcing material is within the range of 0.5-2.0% by weight.

    摘要: The present disclosure concerns a soil or ground quality stabilizer comprising a mixture formed by mixing a burned sewage sludge ash the main contents of which are CaO, SiO.sub.2 and Al.sub.2 O.sub.3 with a lime of calcium hydroxide to reduce hydraulicity and a fine Fe oxides mixture powder byproduced in steel production the main content of which is iron oxide. The soil or ground quality stabilizer is added into a pavement material containing crushed stones, natural soil, etc. to improve the strength and viscoelasticity of the natural soil and can give a desired CBR strength to the soil having an increased moisture content. The preferable adding ratio of the fine Fe oxides mixture powder into the mixture of the burned sewage sludge ash and the lime of calcium hydroxide is within the range of 15-35 weight %.
