Exploring The Use Of Re-Forming Concrete, Moritz Meditz

Bachelor of Architecture Theses - 5th Year

This thesis takes a closer look at concrete construction in the modern area and, more specifically, the use of formwork to shape the built environment.

Traditional rigid concrete formwork has been optimized for buildability while serving structural needs. This mentality means simple prismatic elements that are entirely overbuilt for the task, stacked on top or next to one another. The idea that these elements are the peak of efficiency in concrete production has informed virtually all modern concrete construction. Any shapes that vary from the simple prismatic volumes are seen as challenging to build and expensive. For the most part, …

Concrete Mix Design Using Simple Equations, Hakim Abdelgader, Ramadan Suleiman, Abdalla Adam, Jamal Khatib

BAU Journal - Science and Technology

The behaviour of concrete, whether fresh or hardened, depends basically on the behaviour of its components and the relationship between them, therefore, obtaining a concrete with certain properties depends fundamentally on the concrete mix design. Concrete mix design generally includes two main steps: 1-Selection of the main components suitable for the concrete (cement, aggregate, water, and additives); 2-Determination of more economical mix ratios to fulfil the workability, strength and efficiency requirements. Currently, there are many international methods locally approved for mix designs. They are all related to each other, they give relatively the same quantities of the mix components and …

A Material Affair: The Intimacy Between Materials And Affective Space, Rex Hughes, John Mikesh

Architecture Senior Theses

This thesis argues that an architecture embracing innate material qualities, deployed for choreographed sensory experiences, will open a more intimate dialogue between humans and their environment. This thesis is rooted in the idea that the most powerful experiences are those that stimulate all the senses at once. This is illustrated by architect Lisa Heschong, who explains that fire fascinates humans because it glows, crackles, smells of smoke, and gives off heat. This intimate sensory experience provides an archetype for the way users may be seduced into engaging affective environments through haptic materials.

In an investigation of material qualities (density, hardness, …
