Abstract
At present for decoration facades of buildings are used ventilated facade systems, that allow restoring the old facades by giving them a more modern look. As a covering material, these systems use different materials, among them fiber cement board (FCB). However, they have high cost and they cannot always be used for building in harsh weather conditions like in Russia.
The most widespread and available facing material on the domestic Russian market is fiber cement panels, based on the asbestos fibers. Due to the meanwhile proven carcinogenicity of asbestos, the demand for these products is decreasing year by year to almost zero.
Therefore, it becomes urgent to develop a new effective facing material made from environmentally safe and pure raw materials of low cost, capable of ensuring the reliability, durability and energy efficiency of buildings. One of these materials are FCB on the basis of cellulose fibers.
Existing FCB based on the cellulosic fibers have following disadvantages: low strength, high water absorption and low resistance to frost. These problems require urgent work to develop issues of quality and durability of FCB, based on cellulose fibers.
Based on the realization of three-factor plan of the second-order, the influence of modifying agents on physico-mechanical properties and durability of fiber cement boards, based on cellulose fibers was investigated.
