Impact of Climate Change on the Optimization of Mixture

A genetic algorithm (GA) is used to find the optimal mixture with the lowest CO2 emissions considering the requirements of strength, carbonation durability, and workability. Second, we clarify the effect of cost on the mixture design of low-CO2 concrete. A genetic algorithm is also used to find the optimal mixture with the lowest cost.

Optimization of ultra-high performance concrete

An optimization experimental program was designed to identify a desired balance of key mix design parameters for an economical ultra-high-performance concrete (UHPC) mixture. The following mix design parameters were evaluated: superplasticizer content, coarse-to-fine aggregate ratio and steel fiber volume fraction.

Posttensioned Concrete - Portland Cement Association

The concrete component is cast with steel reinforcing strands installed in a way that protects them from bonding with the concrete. This practice gives designers the flexibility to further optimize material use by creating thinner concrete members. The materials used to post-tension concrete members are ultra-high-strength steel strands and bars.
