Hi Michael,
You will find a lot of information in the following reference
1. ASTM Special Technical Publication, Proceedings of the 1997 Symposium on Design and Application of Controlled Low-Strength Materials (Flowable
Fill) ,1997 n 1331 May 1998 St. Louis, MO, USA ISSN: 1040-3094 .
I hope this helps,

Objet: Flowable fill, self compacting concrete, etc
Have any list members had experience with the material variously known as
flowable fill, self compacting concrete, etc?
I am considering its use as a structural fill material beneath a shallow
foundation. The thickness of fill required is such that a compacted
soil/aggregate fill will permit excessive settlement. The material would be
seasonally submerged.
The sort of things I would like to know about this material are:
1. What range of strengths can be expected?
2. What range of compressibility properties can be expected (elastic
modulus, subgrade modulus, etc.)?
3. How difficult are these properties to predict and control?
4. Is the variability of these properties very high?
5. For strength and stability considerations, is it best to consider
effective stress, drained, behaviour; total stress, undrained, behaviour;
or ????? Or should it be considered a soil, or soil-like, at all?
Any suggestions, or experiences, would be appreciated.
