Abstract: Measuring area of irregular shapes is essential for many applications in Geomatics engineering, Civil engineering, Agricultural sciences, and Medical sciences.
Introduction Measuring area of irregular shapes is essential for many applications in Geomatics engineering, Civil engineering, Agricultural sciences, and Medical sciences.
In this method an instrument called a planimeter either ordinary or digital is used, and the method has been widely used for many applications by surveying or geomatics engineers, highway engineers, agricultural engineers, and medical professionals.
It is useful for many fields that required measurement of irregular shapes, particularly in geomatics or surveying engineering.

Introduction The alarming deterioration of our world’s infrastructure has caused civil engineers to seek new ways of rehabilitating aging structures.
Many researchers have conducted specific experimental and analytical studies on potential applications of FRP composite materials for civil structures, such as highway structures[1-4], internal reinforcements in concrete structures[5-8], externally bonded reinforcements in structural repair and strengthening[9-12].

Long-term Bonding Strength Between Flue Gas Desulfurization Gypsum and Polymer Cement Mortar Ru Mu1,2, a, Ling Wang1,2,b, Wenling Tian1,2,c and Wei Cao1,2,d 1School of Civil Engineering Hebei University of Technology, Tianjin 300401, P R China 2 Civil Engineering Technology Research Center of Hebei Province, Tianjin 300401, P R China armu@hebut.edu.cn, bwlark@sina.com, cwltian@hebut.edu.cn, dcc.2212@163.com Keywords: flue gas desulfurization gypsum; polymer mortar; bonding strength.
In civil engineering, walls inevitably connect with concrete beams or columns.
Also, to use FGD gypsum as a civil engineering material in practice, its long-term behaviour must be tested.
The results of 6 month observation of the two multi-layer blocks prove that the bonding of polymer mortar a FGD gypsum is durable, at least in the test period, and the two different materials can be used together in civil engineering.
