Several studies have investigated the properties of alkali-activated materials (AAM), considering it as a substitute cementitious concrete. However, on self-consolidating concrete (AASCC) are extremely limited. This paper AASCCs utilizing ground granulated blast furnace slag (GGBFS) main precursor. Single, binary, and ternary were produced using fly ash Class-F (FA) silica fumes (SF) replacemen...

Self-consolidating concrete (SCC) has been developed for use in precast prestressed concrete bridge girders in the state of Minnesota. Locally available materials were used with a number of cementitious and filler materials, including ASTM Type III cement, Class C fly ash, and blast furnace slag. SCC was successfully proportioned with both natural river gravels and crushed stone as coarse aggre...

Adequate selection of material constituents and test methods are necessary for workability specifications and performance of hardened concrete. An experimental program was performed to evaluate the suitability of various test methods for workability assessment and to propose performance specifications of prestressed concrete. In total, 33 self-consolidating concrete (SCC) mixtures made with var...

Modeling is a very useful method for the performance prediction of concrete. Most of the models available in literature are related to the compressive strength because it is a major mechanical property used in concrete design. Many attempts were taken to develop suitable mathematical models for the prediction of compressive strength of different concretes, but not for self-consolidating high-st...

semiconducting carbon nanofibers (cnf) are prepared from three different sources, i.e., acetylene, ethanol, and cotton by the chemical vapor deposition (cvd) process. these fibers are having rich elastic, engineering and conductivity properties. fresh self-compacting concrete (scc) flows into place and around obstructions under its own weight to fill the formwork completely and self-compact, wi...
