In practice, the C/S of pastes may be altered by adding reactive, silica-rich pozzolanic materials such as silica fume, fly ash and metakaolin, however, the latter two materials also introduce much alumina in potentially reactive form.

The delivery process of sustainable construction particularity becomes more complex by using environmentally-friendly building materials, construction standards and decreasing environmental load.
On the one hand, the process management can recognize the waste and improve efficiency in the use of building materials, reduce the construction cost; on the other hand, it can guarantee the stability of the workflow through the plan and control system.
Extending the service life of building is a sustainable method, which relatively reduce the material consumption.
With the rapidly development of construction industry, we must aware of that the science is all-inclusive.

Three kinds of canopy have some characteristics of single material, design standardization, industrial component manufacture, high degree precast assembly of on-site installation, rapid construction.
Canopy roof material is generally profiled color steel plate and arch-pressure plate.
E Defects of building material Instantaneous tensile, compressive and shear strength of material is considered in the design, although calculation value of the strength meet the requirements, with the increase of service life, fatigue stress of steel structure increases, so bearing capacity of steel structure also reduces.

Introduction Indonesia’s pharmaceutical industry relies heavily on imports, with 90% of its raw materials reportedly sourced from other countries [1-4].
This development has the potential to reduce Indonesia's reliance on imported raw materials while addressing domestic demands for analgesic and antipyretic drugs.

Electronic structure and doping effect of Ni and Co in the kink on the edge dislocation of bcc iron Li-qun Chen a and Zheng-chen Qiub College of Sciences, Central South University of Forestry & Technology, Changsha 410004, China aldclqun@163.com, bclqun123@sohu.com Keywords: Electronic structure, doping effect, alloy element, dislocation, kink Abstract: Using the first-principles self-consistent discrete variational method based upon density functional theory, we investigated the energetics and the electronic structure of the 3d impurities Ni and Co in a kink on the [100](010) edge dislocation (ED) in bcc iron.
Dislocations are always present in most crystalline materials and influence a variety of properties, including mechanical, electric, optical and magnetic [2].
It is commonly accepted that the dislocation motion in materials having a high Peierls relief is accomplished by the nucleation and propagation of kinks along the dislocation line [2].
However, this very transparent but simplified concept is insufficient to describe the mechanical properties of real materials, where the impurity-kink interactions play a crucial role in kink dynamics.
