A Technical Analysis on the Use of Industrial Waste Fibers in the Production of Non-Autoclaved Aerated Concrete Masonry Block Elements

Abstract

The presence of non-autoclaved aerated concrete masonry block elements in recent years is among the product derivatives that have become increasingly important and widespread in the development of lightweight construction materials. It can be seen that it is increasingly preferred especially in non-load bearing building units due to its low unit weights, porous structure and ease of application and technical advantages such as insulation properties. Non-autoclaved aerated concrete masonry block elements can be made with the use of many different materials, especially the use of fiber additives of different lengths and origins as matrix reinforcement materials gains a special importance in terms of recovery of industrial wastes.
In this paper, preliminary findings of an ongoing experimental research and development study on the reinforcement effect in matrix structure of 3 different fiber types that can be considered in the industrial waste fiber category are technically discussed. This research study focuses on the production of non- autoclaved pre-cured, expanded masonry block elements using fiber additives. Two of these fiber types are fiber materials obtained from the recycling of denim fabric by opening denim fiber. In this study, these fibers are coded as Fiber 1 and Fiber 2. The fiber type, coded as fiber 1, has a cotton/synthetic ratio of 90/10. Its maximum fiber length is 3 mm. In the fiber type coded as fiber 2, it has a ratio of 70/30 cotton/ synthetic. In addition, the maximum fiber length of this fiber material is 2 mm. The fiber, coded as Fiber 3, is a medium-sized, 100% natural, highly pure cellulose white fiber with an average fiber length of
~200µm, obtained from recycling industrial paper waste. 

In this study, the effects of different fiber usage rates and fiber suitability are examined on non-autoclaved aerated concrete masonry mortar samples prepared with industrial different fiber wastes. Based on the findings, the effects of the types and amounts of materials used in the mixtures on the technical properties of non-autoclaved aerated concrete block element samples are analyzed in detail. The physical and mechanical properties of the new generation building element samples such as unit weight, compressive strength, water absorption by mass, porosity and thermal comfort properties are discussed in this paper with industrial approaches.
