PRELIMINARY INVESTIGATIONS OF PERMACRETE.

Ultimate flexural strength and certain creep properties of single-size soil-material aggregates cemented by ice are investigated. The relation of ultimate strength to particle size and temperature is given in the form of graphs. Rules for mixing various sizes are established, and their validity test...

Description
Summary:Ultimate flexural strength and certain creep properties of single-size soil-material aggregates cemented by ice are investigated. The relation of ultimate strength to particle size and temperature is given in the form of graphs. Rules for mixing various sizes are established, and their validity tested under field conditions. Experimental construction in permacrete (artificial concreteaggregate mixtures cemented by ice) disclosed that it should be applied and handled like concrete, providing the temperature is below the freezing point. Permacrete, although dissimilar to concrete in many important properties, may be used successfully as a building material in place of concrete. Its low cost and the availability of ingredients can make permacrete an important building material in permafrost regions. (Author)
