In the case where the fine brick wastes are used in the SFHPC without further addition as fine silica fume.
Yes, according to some research it is possible. But, getting SFHPC is not the only objective, that's why many other parameters are in investigation.
For your better understanding I can suggest you a research paper titled, "Performance of concrete produced with crushed bricks as the coarse and fine aggregate"
(Link: http://iaeg2006.geolsoc.org.uk/cd/PAPERS/IAEG_616.PDF)
In another article titled, Utilization of crushed clay brick in concrete industry, the authors proved that the use of recycled aggregate and dust made of clay bricks is promising in many applications where the thermal resistance, cost and environmental aspects are imperative.

Dear Imrose Bin Muhit
I mean, the use of brick waste as fine powder (after grinding) to replace silica fume, not as coarse or fine aggregate.
To some extent at a specific water cement ratio, also considering the factor of SFHPC to be used for / as / in.
If the crushed ceramics bricks have the adequate fineness (por example the retained in the mesh No. 200 (74 micras) is under 10%, may be and excellent pozolan to be added to concrete in certain proportions respecting the cement content, with the use too of a good superplasticizer admixture (some type of vinilic or acrilate) is really possible to obtain a high performance concrete.
yes, it is can get a good concrete.
the clay must have a high fineness,its performance will also be better if the cooking has not reached 900 ° C, because if present kaolin clay, metakaolin this has passed which is a pozzolanic material
Yes Riad, fine of Bricks can replace silica fume, because the procedure of cooking in the production of Bricks in Algeria not exceeds 900C, then it may be yet reactive, as Yimmy said.
I think you will have good concrete with this fine material.
Good luck Riad
