Abstract: The creation of new building materials requires serious research on fiber-reinforced concrete, which includes renewable and environmentally friendly plant fibers: bamboo, sisal, straw, coconut, etc. These studies have been actively conducted since the middle of the 20th century. Scientists have found that the mechanical characteristics of fiber-reinforced concrete, including flexural and compressive strength, heat resistance and crack resistance, depend on the properties of the fibers themselves and on their amount in the concrete composition. The article analyzes test data for concrete with the addition of coconut fiber. The results showed that 2 % coconut fiber increased the concrete’s flexural strength, axial compression, and crack resistance. According to its mechanical characteristics, such fiber-reinforced concrete meets the requirements for certain types of concrete, and can be used as a «green» building material.
Keywords: concrete, coconut fiber, bending strength, compressive strength, crack resistance.
