“…The results were tabulated in Table 4 to understand the varying trend of the compressive strength due to the addition of polypropylene fibers. Researchers (15,16) revealed that, in order for the foamed concrete to be suitable for structural purposes, it must possess a compressive strength of at least 25 MPa after 28 days.…”

Objectives:The research explores the effect of adding polypropylene fiber in foamed concrete. Methods/Analysis: The manuscript discusses the mechanical and durability properties of polypropylene fiber reinforced foamed concrete. Fly ash, copper slag, and polypropylene fiber were admixed for strengthening the foamed concrete. The experimental analysis is carried out with polypropylene fibers at 0%, 0.25%, 0.5% and 0.75% by volume of concrete. Image processing analysis through MATLAB was done to validate the mechanical and durability properties. Findings: The results showed that, the optimum quantity of fiber reinforcement is found to be 0.25%. There was an increase in compressive, split tensile strength and flexural strength of 13.6%, 16.7%, and 30%, respectively, with 0.25% fiber. The durability test results suggest that these values are acceptable for constructing durable concrete structures limited to non-structural applications. The results were validated using image processing analysis through MATLAB software. Economic analysis showed that the foamed concrete reduces the structural dead load by almost 35.3%. Novelty/Improvement: It is recommended that the polypropylene fiber reinforced foamed concrete would be feasible for durable concrete structures limited to non-structural applications.

Foam concrete is a popular energy-efficient construction material with a fairly wide range of usage in buildings and structures. Increasing ecological efficiency and reducing construction costs by the application of different types of industrial waste in the manufacturing technology of this composite is a promising direction. The main goal of this study is to investigate the possibility of coal dust (CD) waste inclusion in the technology of energy-efficient cellular concrete produced by foam concrete technology. Test samples of foam concrete were made using coal dust by partially replacing cement in the range of 0–10% in increments of 2%. The following primary characteristics of foam concrete were studied: fluidity of mixtures; compressive strength; density; thermal conductivity of foam concrete. An X-ray diffraction analysis of foam concrete composites was performed, which showed changes in their phase composition when using coal dust as a modifier. Coal dust in rational quantities from 2% to 6% improves the physical and mechanical characteristics of foam concrete and increases the structure uniformity. The optimal values of the foam concrete characteristics were recorded at a dosage of coal dust of 6%. At the same time, the density decreased by 2.3%, the compressive strength increased by 15.6%, and the thermal conductivity coefficient decreased by 8.9% compared to the ordinary composition. The use of the resulting foam concrete is advisable in enclosing structures to create high energy efficiency of buildings and structures due to the improved structure and properties.
