Cement Cement is considered to be one of the most important construction materials around the world.
Due to the importance of cement as a construction material, and the geographic abundance of the main raw materials, cement is produced in all countries.
It is well known that the iron and steel industry is not only one of most important raw materials sectors in China, but also energy-consuming.

At the same time, there is a great lot of building materials demand with the development of society and gradual improvement of foundation construction, especially there is lack of enough building materials in the countryside.
In order to develop a new building materials for the Yellow River area low building construction in the countryside, based on the investigation and analysis of the beach area of the lower reaches of Yellow River silt characteristics, clay-based cementitious materials are prepared with the Yellow River silt as main materials, cement, lime and a few of excitant agent as auxiliary materials.
In conclusion, clay-based cementitious materials can be prepared with the Yellow River silt as main materials, cement, lime and a few of excitant agent as auxiliary materials, which provide a new building material for the Yellow River area low building construction in the countryside.

Rice husk charcoal, a kind of new environmentally friendly biomass materials, which is made from rice husk under anaerobic combustion at 300˚C , has been increasingly applied to remedy some polluted sites.
In recent years, biochar was increasingly used as soil conditioner, carbon sequestration and new environmentally friendly biomass materials for remediation of some polluted sites with properties of strong adsorption and low cost [7, 8].
A potential wide prospect when biochar materials were used as wetland brusque has been shining upon reducing transport of pollutant and the bio-availability [9-12].
Materials and methods Rice husk charcoal.
