Crushed dolomite with a nominal size of 8 mm and fine quartz sand with a nominal size of 2 mm were used to produce reactive powder concrete (RPC) in this study. The compressive strength is comparable to that of standard RPC with a maximum aggregate size of less than 0.6 mm. The use of crushed dolomite modified the mixing process and mechanical properties and it was easier to fluidize and homogenize RPC that contained coarse material. The mixing time can be reduced compared to standard RPC. Under compressive, tensile, and flexural stresses, both RPCs behaved similarly, with the exception of a slightly differing modulus of elasticity, which was connected to the stiffness of the utilized aggregates. The results showed that at normal curing conditions, the locally available materials produced RPC with compressive, tensile, and flexural strengths of 134.3, 11.95, and 27.75 MPa, respectively. The study also confirmed the impact of fine aggregate type content and silica fume percentage on compressive, tensile, flexural strengths of RPC and drying shrinkage. Drying shrinkage of RPC including crushed dolomite was reduced because to the decreased paste volume fraction and the impediment of the stiffer crushed dolomite. Additionally, the durability performance was improved in terms of absorption and water permeability, giving ideal use in aggressive environments and effective for corrosion resistance.

“…The bridge is designed and analyzed depending on the quality of the seismic area, soil characteristics, the acceleration factor and the site selection coefficient, as well as the return coefficient of the bridge is determined, so seismic effect is considered in the design. On the basis of the projected yield displacement, the seismic design of construction members as comparison design [5]. Thanks to its high strength, high ductility, and low permeability, reactive powder concrete can be used in design of bridge members to achieve the goal of sustainability [6,7].…”

In this paper, two types of bridges were taken to carry out the analysis and design according to the AASHTO Code and the SAP2000 program, in the beginning, work is done using AASHTO Code and both bridges are designed and analyzed, the first one was the suspension bridge and the second was a bridge supported in the pier region only. The two models, 16 piles with a diameter of 3.8 m were carried out on each pier. After that, the two models are analyzed and designed according to the SAP2000 program to calculate moment, shear and deflection for both bridges. So that the two models are compared based on torque, shear, impact loads and deflection to find out which one of the two models is more suitable for use in a long girder span. The comparison between the AASHTO Code and the SAP2000 program is also made based on the loading to show its effect on the stability design. The AASHTO code and the SAP2000 program are the most appropriate when analyzing and designing for two models. There is a slight difference in moment where the proportions were approximately (6-9)%. As for shear for both methods, the values for the suspension bridge were greater than those of the supported bridge. The difference was about (27-26)%.
