Analysis of the Structure of Cellulose Fibers Using the Imagej Program and Fibercement Properties on their Basis

Abstract

This article presents the results of an experimental study of the effect of morphometric parameters of secondary cellulose fiber from various brands of waste paper on the strength characteristics of cement stone. The article is based on the results of determining the morphometric parameters of cellulose fibers. Visual analysis of microphotographs of cellulosic fibers showed that the smallest fractions of fibers were obtained from newspaper waste paper of grade MS-8V. A causal relationship has been established between the fiber content and the strength of an incident stone. It was found that samples with a content of cellulose fibers of 0.5-0.75% of the mass of cement have high strength. The most durable were samples with the addition of cellulosic fibers based on newspaper recycled paper MS-8V.
