Mechanical Properties and Environmental Evaluation of Ultra-High-Performance Concrete with Aeolian Sand [PDF]

open access: yesMaterials, 2020
Ultra-high-performance concrete (UHPC) has received increasing attention in recent years due to its remarkable ductility, durability, and mechanical properties. However, the manufacture of UHPC can cause serious environmental issues. This work addresses the feasibility of using aeolian sand to produce UHPC, and the mix design, environmental impact, and

Multi-scale study on mechanical property and strength prediction of aeolian sand concrete

Construction and Building Materials, 2020
Abstract The aim of this work is to promote the utilization of aeolian sand for concrete production. The workability and mechanical property of aeolian sand concrete (ASC) is studied. The effect mechanisms of aeolian sand on the mechanical property of concrete are revealed from multiple scales. For the macro scale, use the pressure tester to test the

Cross-scale Study on the Mechanical Properties and Frost Resistance Durability of Aeolian Sand Concrete

open access: yesKSCE Journal of Civil Engineering, 2021
Many researchers have been searching for the alternative for natural river sand as fine aggregate for concrete preparation. Thus, whether it is feasible to replace natural river sand by aeolian sand in concrete partially or totally is studied. At the macroscale, a universal testing machine and concrete rapid freeze-thaw equipment are applied in testing
