In order to effectively manage the layout of large amounts of construction site, construction engineering construction environment and its spatial location information, master the construction management and process trends and track patterns of space and time, for the construction project site, personnel, materials, equipment and construction progress to provide auxiliary decision.
In the construction organization and management quantities are real-time queried to organize manpower, machine, material, etc.

General in writing books, materials, and manuals revealed, people are able to express in words or language, therefore, easier to store and share.
Compared with teachers is in science and engineering research which resulted in the poor condition of college English teachers, academic innovation difficult
First, teachers can use the rich resources of the Internet, downloaded from the Internet or e- book version of the electronic journals and other ways to acquire knowledge; Or use Baidu library, Baidu’s ask Google and other professional websites to find information about the English language; You can also use professional disciplines website or educational website to get the expertise they need.
It may also be linked university English-disciplinary professional website or video materials, etc., to share good knowledge of what they saw.

Without water addition, no strength would be achieved, as the sand and clay would be just two different dry materials.
Materials and Methods The sand mixture was prepared by mixing 1000 grams of dry sand with 40 grams of bentonite clay, and subjected to milling for 5 minutes.
