Crude Fiber Determination Using Ceramic Fiber to Replace Asbestos
Journal of AOAC INTERNATIONAL, 1982 Abstract Crude fiber was determined in a wide range of feed products by a method which specifies ceramic fiber as a filter medium instead of the more hazardous and difficult to obtain asbestos. Results correlated well with those obtained by using AOAC official final action method 7.061-7.065 (correlation coefficient, 0.9994).

International Journal for Research in Applied Science and Engineering Technology, 2023 Abstract: Concrete can be defined as a building material that can be composed by mixing gravel or broken stone, sand, cement, and water. The mixture can be poured into any shape, size of mould, which on hardening gives a solid stone like mass, the strength of hardened solid mass can be increased by adding admixtures.
