The cement-based composite material known as concrete is a brittle material. After the formation of a fracture, the material is unable to absorb force and breaks immediately. Cracks can be caused by microcracks or shear stress in the interfacial transition zone between the aggregates, which is the weakest region in the matrix. The strength of concrete is determined by the link between the particles in the concrete matrix. Cracks can also arise as a result of shear stress. As a result of the widespread usage of concrete in construction, this may present a potential risk to safety. In the event that the concrete is not strong enough to absorb tension, it may result in potentially hazardous circumstances, such as accidents that occur close to the building. The use of pineapple leaf fiber (PALF) into the concrete recipe will result in an improvement in its workability. In the course of this investigation, a variety of PLAF concentrations-0, 5, 10, and 15 wt.% were combined with water, cement, and sand. The purpose of the characterisation was to ascertain the water absorptivity of PALF cement-based composites as well as their mechanical parameters, which included compressive and flexural strength. In order to examine the microstructures of the cement composites, the machines that were utilized were the Universal Testing Strength (UTS) and the Scanning Electron Microscopy (SEM). The composite material that was based on cement was produced by combining water, cement, sand, and PALF. The fiber content of the composite material was composed of 0, 5, 10, and 15 wt.%. According to the findings that were obtained, the incorporation of natural fibers resulted in an increase in the flexural toughness of the composite material, which was 0.611 MPa, and the rate of water absorption by the material was 29.9%. Nevertheless, the compressive stress was reduced to 0.977 MPa as a result of the improper distribution of the fiber and the large length of the fiber. Through the utilization of PALF, which is both biodegradable and renewable, the composite reduces carbon emissions and reduces the amount of waste produced by agriculture, making it a more environmentally friendly option for the building industry.

摘要

The cement-based composite material known as concrete is a brittle material. After the formation of a fracture, the material is unable to absorb force and breaks immediately. Cracks can be caused by microcracks or shear stress in the interfacial transition zone between the aggregates, which is the weakest region in the matrix. The strength of concrete is determined by the link between the particles in the concrete matrix. Cracks can also arise as a result of shear stress. As a result of the widespread usage of concrete in construction, this may present a potential risk to safety. In the event that the concrete is not strong enough to absorb tension, it may result in potentially hazardous circumstances, such as accidents that occur close to the building. The use of pineapple leaf fiber (PALF) into the concrete recipe will result in an improvement in its workability. In the course of this investigation, a variety of PLAF concentrations-0, 5, 10, and 15 wt.% were combined with water, cement, and sand. The purpose of the characterisation was to ascertain the water absorptivity of PALF cement-based composites as well as their mechanical parameters, which included compressive and flexural strength. In order to examine the microstructures of the cement composites, the machines that were utilized were the Universal Testing Strength (UTS) and the Scanning Electron Microscopy (SEM). The composite material that was based on cement was produced by combining water, cement, sand, and PALF. The fiber content of the composite material was composed of 0, 5, 10, and 15 wt.%. According to the findings that were obtained, the incorporation of natural fibers resulted in an increase in the flexural toughness of the composite material, which was 0.611 MPa, and the rate of water absorption by the material was 29.9%. Nevertheless, the compressive stress was reduced to 0.977 MPa as a result of the improper distribution of the fiber and the large length of the fiber. Through the utilization of PALF, which is both biodegradable and renewable, the composite reduces carbon emissions and reduces the amount of waste produced by agriculture, making it a more environmentally friendly option for the building industry.
