Packing density of concrete mix under dry and wet ...

01/02/2014  This was to study the effect of compaction on the dry packing density. For the concrete mix samples in Phase B, only the uncompacted packing density under condition D1 was measured because the tests in Phase B were mainly to study the effects of blending cementitious materials, not compaction. 2.2. Wet packing tests. The test method employed was essentially the same as the wet packing

Abstract It is well known that the packing of particles in concrete has great effects on the performance of concrete, but existing codified methods for packing density measurement are all carried out under dry condition and do not account for the effect of water in the concrete mix.

In this study, both the dry and wet packing methods were applied to concrete mixes containing cementitious materials, fine aggregate and coarse aggregate. It was found that for the entire particle system in a concrete mix, the packing density is higher, the voids ratio is smaller and the filling effects of ultrafine supplementary cementitious materials are better revealed under wet condition ...

17/05/2009  Hydration of a dry concrete mix after the mix has been covered with soil is herein referred to as in-situ hydration. In this study, a series of dry concrete mix footings were hydrated in-situ by burying them in sand and subjecting them to different water treatments. Footings were removed and cored at 4, 12 and 24 weeks. Compression tests on these cores showed that in-situ hydration could ...
