Shrinkage Cracking In Concrete Tilt-Up Construction, Stewart Hooks, Jack Robinson

Architectural Engineering

The purpose of this project is to investigate a particular, undesirable cracking pattern in concrete tilt-up panels that, until now, did not have a known definite cause. The cause of this cracking pattern is hypothesized to be due to shrinkage restraint of the concrete panels. The cracking under investigation occurs at the bottom corners of the Tilt-Up panels, suggesting that the base of the panel is restrained from shrinkage. This project models various components of Tilt-Up Construction that have potential for restraining the panels from shrinking. This project consists of the following main components.

The first aspect of this project …

Concrete Industry Management In Higher Education, Irl Thomas Barajas

Construction Management

This Paper Focuses on the concrete industry and programs that prepare college students for their future in it and to try and implement some sort of concrete program at Cal Poly. The idea to make Concrete Industry Management first came along at Middle Tennessee State University in 1996, but only a few other programs have started at other schools since then. These programs focus on skills for graduates to enter the concrete industry in production, project management, sales, and marketing. They are structured similar to the way Construction Management programs are structured and have similar courses like estimating, sustainability, and …

Self-Healing Concrete In Commercial Construction, James Anthony Frazier

Construction Management

Crack formation is common among concrete used for all different types of construction. While cracking is inevitable in concrete, it can create instabilities that can compromise an entire building’s structural integrity. New advancements are being made in the biological and engineering fields that are providing a solution to this problem. Certain bacteria and chemicals when mixed provide a reaction that creates limestone material to re-heal cracks in concrete. Using these materials to create this reaction, while incorporating the reactants necessary in concrete mixtures for building, it is possible to eliminate maintenance costs and improve building strength over time. Currently, these …

Recyclable Waste Material As Substitute Aggregate In Concrete, Cannon Michael Lynch

Construction Management

Trash pollution is a serious problem that the world is facing and while there are current efforts to clean up the environment, there still exists the issue of what to do with the trash once collected. Waste material, especially plastic, is littering the ocean and poses a serious threat to wildlife. The construction industry makes a good effort of trying to limit its negative impact on the environment, but it can potentially solve the problem of pollution using one specific material, concrete. The best part about concrete is that its compressive strength can be manipulated by adding or removing certain …

Case Study Analysis Of Improving Productivity Rates For Self-Perform Concrete, Johnny Mcdermott

Construction Management

Productivity is one of the most important aspects of a successful construction project, especially if the work is self-performed and not sub-contracted out to another contractor. Usually the success of a project is directly correlated to how well the production has been throughout the course of the job. Often when a project manager notices their job is not doing well and not making their target profits or man-hours, productivity is usually the answer to that problem. This paper will examine the different ways and methods of tracking production that was used by Overaa construction. The focus of this study is …
