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.

In this study, the stabilization/solidification of lead in soils using alkali-activated cementing materials with rich-silicon materials was investigated.
Experimental Materials The blast-furnace slag was originated from Wuhan Iron and Steel (Group) Company.
The chemical components of the five materials were shown in table 1.
On the other side, the hydration of the binders including rich-silicon materials produced C-S-H which had large specific area.

This is an area where technologists, biologists and physicians work together to gain basic knowledge of the physical properties and behaviour of biological materials.
Advances in biomedical technology made possible by this partnership include dialysis machines designed to replace sick and malfunctioning kidneys; hip and knee prostheses; materials and technologies for the work of the heart and blood vessels; artificial heart.
For example, biomimetics is a branch of bioengineering that seeks to use structures and functions of living organisms as models for the design and manufacture of machines and materials.
