Supplementary cementitious materials such as fly ash, silica fume and ground granulated blast furnace slag (GGBS) have been used widely to partially replace cement in producing self-consolidating concrete (SCC).
Binary and ternary mixes were produced with different percentages for each supplementary material including fly ash, silica fume, and GGBS.

Wheel Based Temperature Measurement in Grinding Brinksmeier, E.1, a,Eckebrecht, J.1, b and Wilkens, A.1, c 1Foundation Institute for Material Science, Bremen, Germany abrinksmeier@iwt.uni-bremen.de, bjochen.eckebrecht@iwt-uni-bremen.de, cwilkens@iwt.uni-bremen.de Keywords: Grinding, process monitoring, surface damage, grinding burn Abstract.
In order to develop an industrial applicable solution to the temperature survey in grinding, giving the opportunity to establish control loops in grinding processes, extensive research work was performed at the Foundation Institute of Materials Science (IWT).
In addition to the above, high temperatures in the grinding arc may lead to the admixing of workpiece material to the material of the thermo-pair and thus influencing the temperature behavior of the thermocouple.

Maritime Control Status in Inland Complex Waters The main functions of maritime control can be divided into four parts: navigation management, navigation support, hazardous material management and anti fouling, crews and ships management.
The ways of monitoring hazardous material and other special ships are limited, and pollution emergency response capacity is not strong.
Furthermore, according to the Ex value of each index, the corresponding indexes like hazardous material management and anti-fouling, other maritime control, ships anti-fouling inspection by boarding, anti-fouling contingency plans for approval, maritime law executors training are in the poor level.

Introduction Grain boundaries and triple junctions are the basic structural components of polycrystalline materials.
The material was recrystallised to a mean grain size of 150 µm.
In order to analyze grain growth kinetics in a polycrystalline material the grains have to satisfy the following criteria.
First, Journal Title and Volume Number (to be inserted by the publisher) 5 the grain boundaries have to move toward their center of curvature.

In addition, depending on the number and nature of the materials used, it is possible to adapt properties for specific applications (damping structures).This work proposes the establishment of a new theoretical model of multilayer beam.
Such theories are limited by the result and lead to sufficiently accurate in the following case results: - the height / length ratio is large, - the material is only weakly anisotropic.

Peanut shell is a versatile material, composed of cellulose, lignin and hemicellulose.
This research is of some daily to reach the waste [1] using physical, chemical method for containing the cellulose component processing, to become a good adsorption property of a class of functional polymer materials.
Then, they were dried at room temperature as a comparison group of adsorbent material.
In the next experiment, the other daily waste such as corncob, waste paper will be used as raw materials, hoped to find an adsorption effect best, cost the least modification of cellulose materials, which can play an important role of processing and recycling of heavy metal ions.
