Project description

The project presented in this report seeks to develop a proper methodology to use saturated lightweight sand (LWS) to improve the performance and prolong the service life of concrete mixtures. High-performance concrete (HPC) approved by MoDOT was used for the baseline mixture and was modified with different types and contents of saturated LWS used for internal curing. This was done to evaluate the optimum dosage of LWSs and maximize their effectiveness on enhancing performance.
