Design and Performance of Earth Spillways
The U.S. Department of Agriculture's Soil Conservation Service has designed and administered construction of a large number of dams utilizing grassed earth-lined auxiliary...
Identification of Automation Opportunities
Construction, although the world's largest industry, is also its most archaic. Most construction practices are very labor-intensive, with resulting impacts on safety, productivity,...
Terrestrial Trends for Building Technology in North America
This paper discusses new building technologies that will develop in the early 1990's to become significant technologies by the mid 1990's. The perspective is...
Constraints on Lunar Base Construction
This article discusses the development of scenarios and designs for the construction of a lunar base or network of bases, which will require close attention to the natural and human constraints...
Lunar Resources: What is Known and Expected
The lunar regolith is the source of a number of basic materials which can be utilized in lunar construction. These materials include those which are obtained directly from the regolith...
Environmental Considerations for Lunar Base Engineering
Currently a large number of conceptual designs are being offered for the lunar base involving various types of structural materials and equipment for construction or resource recovery....
Hot Pressing of Lunar Soil and Qualification for Manned Applications
Lunar soil may be fabricated into useful building materials analogous to those used for masonry, concrete and ceramic pipe applications on earth. The process has been analyzed theoretically...
Sintering Lunar Simulants Using 2.45 GHz Radiation
In situ sintering of lunar regolith may be useful for slope stabilization, dust control, and other applications around a lunar base. Having a knowledge of the mechanical properties of...
Use of Alkali Activation of Alumino-Silicates to Form Binders from Lunar Soil
The establishment of a permanently manned lunar base requires construction materials which can withstand the lunar environment and can be obtained from locally available lunar materials....
Cement-Based Materials for Planetary Facilities
The use of concrete and other materials based on a cementitious matrix is evaluated for the construction of planetary base facilities. Consideration is given to the most recent developments...
Concrete Lunar Base Investigation
Scientific and industrial operations on the moon require suitably shielded structures. Small structures for limited scientific activities may be constructed from structural elements prefabricated...
Lunar Cements/Concretes for Orbital Structures
The lunar surface is a rich source of inorganic building materials for large space structures. Lunar anorthosites can be processed into calcium aluminate cements in high temperature, high...
Concrete Production Method for Construction of Lunar Bases
If a permanent lunar base is to be built on the Moon, most of the materials for the construction would be made from in situ resources. From economic viewpoints, concrete would be the most...
Concrete Habitable Structure on the Moon
This paper presents construction methods for a concrete habitable structure on the Moon. The study was conducted on the assumption that a concrete manufacturing plant has already been...
Construction Operations for an Early Lunar Base
Construction and excavation operations performed during the earliest stages of a manned lunar base pose a unique set of problems. This paper will describe six construction tasks that are...
Earthmoving in the Lunar Environment
This paper analyzes the lunar 'earthmoving' process with inputs, outputs, and external conditions acting upon it. Lunar environmental conditions such as temperature,...
A Methodology for Modeling Construction Requirements for a Manned Lunar Base
Before accurate modeling and planning of a manned lunar base can be accomplished, a methodology representing the construction-and-assembly process of lunar surface facilities must be developed....
Use of Non-Terrestrial Materials for Large-Scale Space Activities
As the space program matures, space construction will evolve from assembly and deployment of systems fabricated on the Earth to projects constructed from locally available resources. The...
Intelligent Construction Machines for Initial Planetary Shelter Fabrication
There have been any number of artists panoramas of initial base and habitat construction on other planetary bodies, notably recently the moon. Most of these conceptual drawings assume...
Explosives Research for Lunar Applications: A Review
Experimental explosives research for lunar operations is reviewed. Each research project had a different objective and together their findings showed that using explosives on the moon...
