No Admixture, Sustainable, Self-Consolidating Grout, Craig V. Baltimore Dr Jul 2014

No Admixture, Sustainable, Self-Consolidating Grout, Craig V. Baltimore Dr

Craig V. Baltimore

ABSTRACT: The consolidation of grout in concrete masonry unit (CMU) walls is labor-intensive. Also, the grout’s Portland cement content has a high embodied energy demand – a non-sustainable characteristic. For the labor-intensive issue, chemical admixture self-consolidating grouts have been used in walls 12.67 ft. (3.86 m) tall, however the chemical additive can impose new limitations on the grout (non-robust characteristics). No admixture self-consolidating grout with high percentage Portland cement replacement have potential for robust and sustainable application.

This paper reports on the consolidation of no admixture self-consolidating grout made by substituting high percentages of Portland cement with Type-F fly ash …

This project was designed to provide more insight into the infrastructure challenges of agricultural enterprises in Iowa and to also facilitate the understanding needed to implement broader energy-related policy and planning. This work will also provide farmers and farmer networks with the necessary resources to justify increased local and state investments in the local and regional food systems.

Using Web Scraping Technology To Automatize Cost Data Collection For Calculating Construction Cost Indexes, Joseph Shrestha, H. David Jeong Dec 2013

Using Web Scraping Technology To Automatize Cost Data Collection For Calculating Construction Cost Indexes, Joseph Shrestha, H. David Jeong

Joseph Shrestha

Construction Cost Index (CCI) and Building Cost Index (BCI) published by Engineering News Record (ENR) are two of the very popular cost indexes used in the industry. Many state DOTs publishes their highway construction cost indexes to keep track of the current trend of cost escalation. The ENR BCI and ENR CCI are prepared by collecting cost data from agents of the 20 cities in the country. Such manual process of collecting cost data can be costly. The proposed method of price data collection, based on a computer technology called “web scraping,” can automatically collect material prices and labor wage …

Dwr Based As-Built Schedule –Powerful But Highly Neglected Application Of Dwr Data, Joseph Shrestha, H. David Jeong Dec 2013

Dwr Based As-Built Schedule –Powerful But Highly Neglected Application Of Dwr Data, Joseph Shrestha, H. David Jeong

Joseph Shrestha

Daily work report (DWR) is a very important data recorded by the inspectors during the construction projects. Although, a lot of time and effort is invested to collect this big amount of DWR data, its use has been limited mostly to the contractor payment and dispute resolution. This study presents the methodological details about utilizing the historical DWR data to automatically generate the schedule for future projects based on the bid data. As a proof of concept of concept, as-built schedules has been developed from the DWR data. The as-built schedule generated can be used as a tool for more …
