Modified Damage Model of Aeolian Sand Self-Compacting Concrete

Journal of Engineering Mechanics
Modeling of concrete damage is an important branch of concrete structural analysis; however, the damage behavior of different types of concrete varies. In this study, mechanical property tests were conducted to modify the damage model for aeolian sand self-compacting concrete (ASSC). Damage behaviors and stress–strain curves of prismatic ASSC specimens

Study on erosion damage of aeolian sand concrete by wind-grit flow in Gobi gale area: laboratory experiment and numerical simulation

Case Studies in Construction Materials
The high-energy winds carrying sand and grit in the Gobi gale zone threaten infrastructure along transportation routes. The aeolian sand resources are abundant in this area. The use of aeolian sand instead of river sand to prepare concrete can reduce the

Frost Durability of Self-Compacting Concrete Prepared with Aeolian Sand and Recycled Coarse Aggregate

Materials, 2023
Aeolian sand (AS) and recycled coarse aggregate (RCA) can be reasonably utilized as green materials for concrete modification. The paucity of natural sand and gravel in the construction industry is anticipated to be remedied by the use of these two eco-friendly concrete ingredients. This is incredibly important for environmental protection.
