Special Issue Information

Dear Colleagues,

Composite materials have been widely used in aircraft, ships, and other transportation industries for more than 60 years.  In some industries, however, composites are just becoming a primary material of choice. The use of composite materials in the building and construction industry is growing rapidly. In particular, the modern advantages offered by using reinforced plastics and composite materials are being recognized. They are being used to address structural retrofit design and can be used to reduce life cycle environmental and cost impacts in construction materials. This Special Issue is devoted to publishing papers that describe the most significant research in building materials, repair, and renovation, focusing on a broad range of topics on today's reinforced plastics and composites including:

  • Sustainable composite materials for construction.
  • Polymers (with or without fiber or particulate fillers) intended for engineering uses, including building and construction applications.  
  • Composite material data that demonstrate some unique feature or new phenomenon.
  • Testing, predictive models, analysis, and computational methods for the design of structures constructed from composite materials.
  • Novel processing and fabrication methods.
  • Reviews of special topics such as recycling, environmental effects, novel materials, computer-aided design, predictive modeling, and "smart” composites.
  • Case studies in reinforced plastics and composite materials.

Abstract
This study examines the properties of ordinary and high-strength fiber-reinforced pervious concrete, aiming for a 28-day compressive strength exceeding 40 MPa with a target porosity close to 15%. Utilizing glass fiber (at 0.25% and 0.5% volume ratios) and steel fiber (at 1% and [...] Read more.
This study examines the properties of ordinary and high-strength fiber-reinforced pervious concrete, aiming for a 28-day compressive strength exceeding 40 MPa with a target porosity close to 15%. Utilizing glass fiber (at 0.25% and 0.5% volume ratios) and steel fiber (at 1% and 2%), the study conducts mechanical and abrasion resistance testing on pervious concrete specimens. Sand dust clogging experimental simulations assess permeability coefficients for both application and maintenance purposes, revealing optimized maintenance, including vacuum cleaning and high-pressure washing, can restore water permeability to over 60%. The specific mix designs demonstrate high-strength pervious concrete achieves a 28-day compressive strength ranging from 40 to 52 MPa, with corresponding porosities ranging from 7% to 16%. Results highlight the significant impact of the ASTM C1747 impact abrasion test, where ordinary pervious concrete exhibits a cumulative impact abrasion rate reaching 60%, contrasting with approximately 20% for other high-strength specimens.

There are many cases of carbon fiber-reinforced polymer (CFRP) and reactive powder concrete (RPC) in structural repair and reinforcement, but there are not many related theoretical and experimental discussions. Therefore, the purpose of this research is to focus on the experiment and theoretical calculation of the flexural strengthening of concrete beam specimens. The study was primarily separated into two parts. In the first part, the laboratory tests of flexure strengthening by using CFRP and two reactive powder concretes (RPC1 and RPC2) are used to evaluate the effect of strengthening concrete beams. Secondly, the test value of the maximum flexure failure load of the strengthening specimen using RPC or CFRP and its theoretical value calculated by the transform section method or the ultimate strength method are discussed and compared with their reinforced effect. The test results show that the RPC and CFRP display excellent repair and retrofit potential. The RPC reinforcement material with a thickness of 2 cm and a steel fiber content of 1.0% is approximately equal to the reinforcement effect of three layers of CFRP. In particular, the RPC reinforcement effect is good, and the bonding interface is not damaged. The transform section method could be used to analyze and calculate the maximum flexure failure load of the RPC strengthening concrete beam. The transform section method and ultimate strength method cannot accurately analyze the maximum flexure failure load of the CFRP-strengthening concrete beam. Full article
