Experimental Study on the Manufacture and the Mechanical Properties of Fiber Reinforced Calcium Silicates-Cement Composites Utilizing Fly Ash and Cement Sludge for Construction Materials(II)

플라이애쉬와 시멘트슬러지를 이용한 섬유보강 규산칼슘계 시멘트 복합체의 제조 및 역학적 특성에 관한 실험적 연구

The results of an experimental study on the manufacture and the mechanical properties of fiber reinforced calcium silicates-cement composites utilizing by products (fly ash or cement sludge) for construction materials are presented in this paper. As the test results show, compressive, tensile, and flexural strength, fracture toughness of fiber reinforced calcium silicates-cement composites were improved by increasing the fly ash and fiber contents, but were decreased by increasing cement sludge contents. Somehat, especially increasing fiber contents the fracture toughness of the composites were remarkably increased. Also, the mechanical properties of the composites reinforcing alkali-resistance GF were higher than those of the composites reinforcing Samoa Pulp.
