چکیده انگلیسی
Based on the relations between slump flow (SF), coarse aggregate average diameter (dav,i) and volume of coarse aggregate (Vg,i) used in self-compacting concrete (SCC), it was found that the preferable SF was that coarse aggregate could flow into a compact single layer status when SF testing was taken. Therefore, an improved mix design method of SCC was proposed according to relations among SF, dav,i and Vg,i. In the same Vg,i condition, large dav,i is suitable for small SF, but small dav,i should match large SF. When nominal size of coarse aggregate was 5-20Â mm, proper SF for SCC should be 570Â mm-720Â mm. Results from the validated experiment show that properties of SCC including workability and compressive strength can satisfy the requirements. This improved mix design method helps to further develop SCC and cuts cost in real engineering projects.
