Impact of pH Value and Temperature on Cement-based Materials Adsorbing Heavy Metal Ions Yali Wanga*, Suping Cuib, Xikui Xuc, Mingzhang Land College of Materials Science and Engineering, Beijing University of Technology, 100 Pingleyuan, Chaoyang District, Beijing 100124, China.
Micro-structure analysis shows that cement-based materials’ main adsorption methods are different when pH values are different.
Permeable pavement materials can discharge the rainwater very fast and prevent surface accumulated water.
Summary Cement-based materials have selective adsorption phenomenon for different heavy metal ions (Cu2+, Zn2+, Pb2+, Cd2+).In addition to zinc ions, the cement-based materials’ capacity of adsorbing heavy metal ions increases as the pH value and the temperature increase.

Introduction Nanotechnology is the use of very small particles of material to create new large scale materials.
Obviously, Concrete is one of the major construction materials.
Addition of nanoscale materials into cement could improve its performance.
These are in the development of improved materials and the use of characterization methods to improve the understanding of materials.
Indeed, in the field of pavement, nanoscale materials can be applied to the surface of existing materials to improve aspects such as their hardness, durability, skid resistance and water resistance constitutes potential applications.
