Calculate Lightweight Concrete Aggregates for Constructing Bridges

In recent times, the application of lightweight materials in structural engineering, including bridges, has become a common practice. Besides possessing features like thermal insulation and a longer curing period, lightweight concrete provides a significant advantage in the form of reduced weight compared to normal concrete. Consequently, a more lightweight structure translates to an increased span length, reduced seismic effects, smaller abutments, and piers. This article focuses on the calculation of a lightweight concrete mix specifically for bridge applications and examines the efficiency of internal forces in reinforced concrete bridge girders that utilize lightweight concrete. These results can be utilized as a reference when undertaking bridge construction ventures in Vietnam.
