碩士 === 正修科技大學 === 營建工程研究所 === 102 === Firstly this article used minced wastepaper and soaked, drained, added cement materials and colored powder, made into globular aggregate of different diameters through the processes of water spray , rolling and granulating, poured color wastepaper aggregate concrete, used the color wastepaper aggregate for mixture design, and were made of wastepaper aggregate concrete, then carried out ultrasound, thermal conductivity, compression etc. tests, it is made to discuss strength the relations among curing time, elasticity modulus, and thermal conductivity. First, use the coarse and fine colored wastepaper aggregate carried out cylinder compressive strength and water absorption test, as a selected good aggregate used as aggregate of concrete, and used the United States Bureau of Reclamation mixture method as concrete mixture design, and were made of color lightweight concrete, then concrete is made to discuss the relations among curing time, compressive strength, elasticity modulus, and thermal conductivity ratio. A series of tests are made to obtain the regression curves as references for engineering and construction. The research results show that, in all concrete mix ratios, its elasticity modulus, dynamic elasticity modulus, dynamic shear stress modulus, compressive stress velocity and shear stress velocity all increase with the growth of the square root of compressive strength, Thermal conductivity falls between 0.188 W/m*K and 0.259 W/m*K, Its thermal conductivity is only half the normal weight concrete, indicating that wastepaper aggregate concrete is good material.
