Therefore, in order to improve the compaction of silt and the construction speed, this paper studied the engineering properties of soil and compacted construction technique of high water content of silt combined with indoor and outdoor tests.
In accordance with the Test method of soils for Highway Engineering JTJ051-93, heavy compaction was chosen.
Uneven drying will cause many engineering problems, such as uneven degree of compaction, influencing time limit of a project and subgrade subsidence deformation.

Introduction The mortar finishing layer has been widely used in decoration and thermal insulation system of building exterior wall in China, and the good effect has been achieved in engineering application.
There have been many foreign scholars who studied the infrared thermography in quality control of building exterior wall [1-4], and the good effect had been achieved in practical engineering application [5-7].
But in China，there are relatively few research [8,9] and reported engineering application cases [10,11].

Study on the Influence of Stone Dust on Adaptability of Polycarboxylate Superplasticizer and Cement Yuchuan Jiang1,2,a, Yang Wang2, Da Huo1, Jine Xu2,b, Haochun Yan2 1College of Architecture and Civil Engineering, Beijing University of Technology, Beijing 100124, China 2 China Building Material & Certification Group Co.
Many scholars [5-8] studied the adaptability of fly ash, cement and superplasticizer, and a lot of reference data was provided for the application in engineering.
The influence of stone dust on adaptability of polycarboxylate superplasticizer and cement is studied in this paper in order to provide reference data for application of polycarboxylate superplasticizer in engineering.
The proportion of cement and fly ash is 4:1, which is similar to fly ash content of 15%~25% used in engineering.
So stone dust content of artificial sand needs to be controlled strictly in engineering.
