Project Grant
Overview
Grant Description
Purpose: The purpose of this grant is to deliver a framework that evaluates the risk for concrete foundations to exhibit premature failure due to reactions of PYRRHOTITE-BEARING AGGREGATES.
Activities to be performed: The proposal will perform the following four activities:
Task 1: Validate a modular sampling, testing and analysis protocol to evaluate risk of damage combining field data and a laboratory-based accelerated testing method.
Task 2: Address a series of specific questions related to deterioration mechanisms and damage evolution through isolated laboratory investigations.
Task 3: Advance the development of a risk assessment framework based on expanded data sets in terms of number of samples and type of data relevant to the deterioration mechanisms.
Task 4: Apply the testing protocol for risk assessment to evaluate the effectiveness of proposed mitigation methods in decelerating or halting reactions and associated damage.
Expected outcomes: A dataset of accelerated testing conditions and their impacts on the dimensional, mineralogical, and integrity (crack network) of the concrete; a test protocol for accelerated damage testing of concrete containing PYRRHOTITE BEARING AGGREGATES; results on the timeframe of deterioration under accelerated test conditions; a large field-testing dataset as required for the tiered risk assessment framework; a comprehensive dataset for phase transformation kinetics in different types of aggregates containing varying types and concentrations of sulfide minerals (PYRITE and PYRRHOTITE); a tiered risk assessment model that will combine basic parameters such as total sulfur (and associated sulfide concentration) and home age, with results of accelerated testing of field concrete specimens to evaluate the probability of cracking within a given timeframe; and a summary write-up of the effectiveness of potential mitigation approaches.
Intended beneficiaries: Concrete engineers, building industry, business and home owners.
Subrecipient activities: The recipient does not intend to subaward funds.
