Self-Compacting Earth-Based Composites: Mixture Design and Multi-Performance Characterisation
نویسندگان
چکیده
A new generation of self-compacting earth-based composites (SCEC) for vertical elements with fully exposed earth, in which the main feature is elimination compaction, proposed current work. The first objective was to develop mixture compositions locally available raw materials and achieve self-compactability. Portuguese soil, typically employed rammed earth construction, stabilised using cementitious a superplasticiser ensure flowability. design studies allowed flowable fresh composites. Results on hardened state showed that SCEC presents high compressive strengths (5–14 MPa). electrical resistivity increased time achieved at least 5600 Ωm 28 days, while mass loss after 14 days controlled environment room. Additional tests were performed selected optimal mixtures: drying shrinkage water capillary absorption, promising results. Overall, this work provided initial boundaries assessment opened door further novel construction techniques.

Ultra High Performance Self Compacting Concrete
Experiences in the development of Ultra High Performance Concrete found a very high flowability in concrete with low water powder ratio. Because of the high viscosity of the cement paste, compaction was necessary. To improve the compaction characteristics of the concrete the idea of adding coarse aggregate was developed. The first tests showed a good workability of the fresh concrete and a good...
متن کاملSelf-Compacting Concrete - Procedure for Mix Design
Self-compacting concrete is a fluid mixture suitable for placing in structures with congested reinforcement without vibration. Self-compacting concrete development must ensure a good balance between deformability and stability. Also, compactibility is affected by the characteristics of materials and the mix proportions; it becomes necessary to evolve a procedure for mix design of SCC. The paper...

In this study, first, different mix design of four types of Self-Compacting Concrete (SCC), 1. SCC consisted of only nanosilica, 2. SCC included only microsilica, 3. SCC consisted of both microsilica and nanosilica and 4. SCC without microsilica and nanosilica called as control mix, were casted and tested to find out the values of the Slump Flow, L-Box and 7 and 28 days compressive strength. Th...
