Exploring the Potential of Low Cement Concrete through a Student Concrete Competition

A common method used to increase the strength of concrete is to add more cement to reduce the water-to-cement ratio. However, this is not always acceptable as adding more cement increases autogenous shrinkage, thermal and shrinkage cracking, and the cost of concrete production. By appropriately using superplasticizers, high-performance low cement concrete (LCC) can be produced. This study explores the potential of LCC by limiting cement content,...
