摘要

本研究评估了当高炉矿渣（BFS）和硫铝酸盐分别以20%、25%和30%以及5%、7%和9%的水平取代水泥时，混凝土路面的力学性能和耐磨性。为此，总共制作了10个混合设计并固化28天。结果表明，含有两种添加剂的混合物的抗压强度均有所下降。相反，BFS20-G7混合物满足所提出的最小抗压强度。然而，含有20%BFS和7%Gilsonite的BFS20-G7的弯曲强度和拉伸劈裂分别增加了约4%和7%。宽轮磨损试验结果表明，含有20%BFS-7%Gilsonite的混合物在100和300转中的耐磨性分别提高了约5%和17%。总之，可以建议在公园和车道等交通流量较低的区域使用BFS20-G7。

Laboratory study on the properties of concrete pavement containing blast furnace slag and Gilsonite

This study evaluated the mechanical properties and abrasion resistance of the concrete pavement when cement was replaced by the blast furnace slag (BFS) and Gilsonite at levels of 20%, 25%, and 30%, as well as 5%, 7%, and 9%, respectively. For this purpose, a total of ten mixing designs were made and cured for 28 days. The results showed that the compressive strength of mixtures containing two additives decreased. In contrast, the BFS20-G7 mixture satisfied the proposed minimum compressive strength. However, the flexural strength and tensile splitting of the BFS20-G7 containing 20% BFS and 7% Gilsonite increased by about 4 and 7 percent. The Wide Wheel Abrasion Test results showed that the mixture containing 20% BFS-7% Gilsonite increased the abrasion resistance by about 5% and 17% in 100 and 300 revolutions, respectively. Conclusively, using BFS20-G7 in low-traffic areas such as parks and driveways can be suggested.

期刊介绍： The Electronic Journal of Structural Engineering (EJSE) is an international forum for the dissemination and discussion of leading edge research and practical applications in Structural Engineering. It comprises peer-reviewed technical papers, discussions and comments, and also news about conferences, workshops etc. in Structural Engineering. Original papers are invited from individuals involved in the field of structural engineering and construction. The areas of special interests include the following, but are not limited to: Analytical and design methods Bridges and High-rise Buildings Case studies and failure investigation Innovations in design and new technology New Construction Materials Performance of Structures Prefabrication Technology Repairs, Strengthening, and Maintenance Stability and Scaffolding Engineering Soil-structure interaction Standards and Codes of Practice Structural and solid mechanics Structural Safety and Reliability Testing Technologies Vibration, impact and structural dynamics Wind and earthquake engineering. EJSE is seeking original papers (research or state-of the art reviews) of the highest quality for consideration for publication. The papers will be published within 3 to 6 months. The papers are expected to make a significant contribution to the research and development activities of the academic and professional engineering community.
