Emerging Rapid Aggregate And Concrete Test Methods For Formulating Asr-Resistant Concrete, Anol Mukhopadhyay, Kai-Wei Liu Nov 2019

Emerging Rapid Aggregate And Concrete Test Methods For Formulating Asr-Resistant Concrete, Anol Mukhopadhyay, Kai-Wei Liu

International Conference on Durability of Concrete Structures

The main objective of this study was to develop rapid aggregate and concrete test methods and a combined innovative approach for formulating performance based ASR resistant concrete mixes. An innovative step by step approach has been developed to formulate ASR resistant concrete mixes based on four recommended steps. In step 1, determination of aggregate ASR composite activation energy (CAE) and threshold alkalinity (THA) by using a rapid aggregate chemical test called volumetric change measuring device (VCMD) is performed. The lower the CAE the higher the reactivity is. Based on the measured CAE and THA, mix design formulation is conducted in …

Data For Stromboli Volcano: An Infrasound Primer, Jeffrey B. Johnson Apr 2019

Data For Stromboli Volcano: An Infrasound Primer, Jeffrey B. Johnson

Boise State University Infrasound Data Repository

This Stromboli data is intended for use with a volcano infrasound tutorial, which includes volcano infrasound processing routines in MATLAB. These routines comprise data calibration, data display, spectral analysis, filtering, array processing, event classification, coherence analysis, and source localization. The data provided correspond to a three-array network deployed at Stromboli during a week in September 2018 as part of the BaCIO workshop organized by INGV Rome in conjunction with the Naples Cities on Volcanoes 10 conference.
