In resent years, although there are reports[2-5] about the applications of metal tailings, which occupies over 1/3 component of industrial solid waste, to building materials, mine or roadbed filling and other aspects, their comprehensive utilization rate can only be about 7%, far behind the average rate of 60% in foreign developed countries’[6].
Moreover, the data obtained in the experiments were compared with cement-based materials like cement mortar and the cement-mixed soil under the same conditions.
Raw materials and proportioning design The superfine iron tailings for experiments, a high-silicon-based one, come from Anshan Iron and Steel Group Mining Gongchangling, which belongs to a kind of common cyclone-type dam tailings (the main mineral components are in Table 1.

Further study is necessary in order to develop new substitute raw material for silica gel production by using agarwood waste.
Agarwood oil is frequently used in Middle East and Europe as mixing material for perfume and balm [5].
Materials.
The sample undergoes heating rate until 700°C, since the remaining material is assume to be stable that does not require further degradation.

Building on circular economy characterized by closing material cycle, to achieve the harmony of human and nature, the economic development and environment protection win-win strategy goal is an inevitable trend.
Mode of circular economy is a kind of economic development model, featuring material circulation in a simulation of ecological communities, on the way of material continuous recycling and circulation substitution.
Follow the mode of circular economy “recovery---reuse---design---production”, model on the material circulation method of natural ecological system, form industrial symbiosis combination sharing resource and exchanging by-product between different enterprise, make the waste generated become raw materials in the downstream production process, to reach mutual resource optimization.

The largest proportion of human exposure to radiation comes from natural sources of external radiation, including cosmic and terrestrial radiation and from inhalation or ingestion of natural radioactive materials [1].
Gamma spectrometry The gamma activities of radionuclides (131I, 137Cs, 134Cs and 40K) in 90 human urine samples were determined by employing a high–purity germanium detector (HPGe, CANBERRA Model GC 2018) (refer with: Fig. 2) and gamma spectrometry analysis system at Nuclear and Material Physics Laboratory Department of Physics Faculty of Science Thaksin University.
