Abstract:

Potential of wastepaper fibers for the reinforcement of thin-sheet cement products was investigated. The slurry-dewatering method followed by pressing was used to manufacture the products. The fiber reinforcement conditions, matrix mix composition, and processing variable were optimized through experimental studies and statistical analyses based on fractional factorial design of experiments and analyses of variance of results. The results are indicative of strong potentials for the recycling of wastepaper for the reinforcement of thin cement products.

Abstract:

Since the turn of the century, thin-section asbestos-cement sheet and pipe products have been manufactured. Health and environmental concerns regarding the use of asbestos have led to a worldwide search for alternative fibers. Paper reviews the state of the art in using synthetic fibers to replace asbestos in fiber-cement products.

Abstract:

A methodology is presented that allows calculation of plain and fiber reinforced concrete for moments and normal forces. The developed procedure is a simple method to derive the internal forces, crack width, effective stiffness, and toughness. The basis for verification of the proposed analytical procedure comprises broad parametric experimental studies that include variations of the fiber diameter, fiber length, fiber content, and depth of the specimen. Interaction diagrams are given for practical use.

Abstract:

SP-146 Since the use of asbestos fibers is totally banned in the industrialized countries and discouraged in almost all countries, a large number of researchers around the world are working to obtain a replacement. Various forms of fabrics, meshes, and discrete fibers made of metal, mineral, polymeric, and naturally occurring materials have been investigated.

Volume:

Abstract:

A comprehensive experimental program based on the statistical concepts of fractional factorial design was conducted to investigate the effects of various mix variables on the physical properties of wood fiber reinforced cement composites. The variables investigated were fiber type, fiber content, pozzolanic admixture, and silica sand content. The composites were produced through slurry-dewatering, and effect of the preceding variables on the following properties were studied: specific gravity, water absorption, and moisture movement.
