Project Objective

To date, no in-depth study has been undertaken in Missouri to study the optimization of HPC involving locally available materials. This project will consist of a state-of-the-art literature search on the durability performance of HPC, an optimization study on HPC mix proportioning using locally available materials for durability / service life performance.

Project Abstract

Commercially available materials will be used throughout this investigation for laboratory produced concrete. Optimization of mix proportions will be accomplished through a trial batching series investigating the interaction of various materials in the production of HPC. The trial series will involve mix designs with the following upper and lower bound limits: w/cm ratio of 0.2 to 0.45 by wt., coarse aggregate content 36 to 44 % by wt., and fine aggregate content 25 to 40 % by wt. Performance will focus on durability enhancement and mechanical property performance such as strength-gain and elastic modulus. Standard test methods will be utilized to quantify optimal mechanical and durability performance. The study also aims to advance the current state-of-the-art regarding HPC durability performance.

Anticipated Benefits

If guidelines / recommendations which result from this study are implemented through a performance-based specification methodology, new Missouri highway structures will result in reduced construction costs, reduced maintenance costs, and longer service life benefiting Missouri and Missouri residents financially for decades to come.
