Engineering Characteristics of Concrete Made of Desert Sand from Maowusu Sandy Land

Article Preview

Abstract:

The desert sand from Maowusu sandy land is very fine aggregate. Currently, there are no national specifications concerning the application of desert sand with very fine grain. To apply the desert sand to concrete in civil engineering, concrete specimens made of the desert sand had been tested in order to clarify its engineering characteristics. On the basis of determined chemical composition and physical characteristics of the desert sand, the mechanical properties of concrete made of fine aggregate from Maowusu sandy land were investigated. The results of the tests indicated that the desert sand could be used as a fine aggregate in concrete for general civil engineering. At the same time, the desert sand was used to confect high strength concrete, the strength and workability of which met general engineering requirement, which provided references for high strength concrete preparation in these regions
