An investigation on the application of acrylic resin agent for fiber/matrix bond strengthening in green engineered cementitious composites (ECC)

Case Studies in Construction Materials, Journal Year: 2024, Volume and Issue: 20, P. e03355 - e03355

Green cementitious materials are usually developed by the addition of high volumes mineral fillers. However, minerals can result in reduction mechanical strength. ECCs obtain their superior behavior from a volume fraction fibers. In ECCs, matrix's strength and bond between fibers matrix is critical parameter, if it becomes weak, whole composite weak or may pull out matrix. this study on green to increase also fiber/matrix bonding, acrylic resin used 4 contents (e.g., 0, 2, 4, 6% weight). The tests performed ECC plain cement paste (PCP) included tensile, compressive, flexural. results show that increases tensile strength, about 2.0 MPa, up 20%, compressive increased 88 MPa 100 MPa. Due ductility, energy-based indexes more significantly. Acrylic optimum content was measured as 1.5 2.7% (by trends effective for because, enhancing bonding fiber. Seeking relationship results, nonlinear regression used, governing equations were presented. Also, using model, parameters predicted successfully input parameters.
