Each one has specific uses based on its composition and properties.
Conventional Concrete Conventional Concrete, also known as normal concrete or conventional vibrated concrete (CVC), is a dense aggregate mix that requires mechanical vibrations and/or poking to remove air pockets that become trapped during the pouring and mixing process.
The width of the circular concrete pile is measured giving you slump flow value.
Conventional concrete, without any admixtures, generally has a slump flow value of about four inches.
The performance of the developed mixtures was evaluated by testing the fresh properties, compressive strength, splitting tensile strength (STS), flexural strength (FS), and impact loading (drop weight on cylindrical and beam specimens).
The results indicated that inclusion of CR decreased the compressive strength, STS, and FS of the tested mixtures, while the impact resistance obviously increased.
Sands and crushed stone, usually crushed to approximately 3/8 inch, make up the fine aggregate portion of the mix.
Viscosity-modifying agents are pseudo polymers designed to reduce aggregate segregation (clumping) that can be problematic with conventional concrete.and there is no way to check and therefore no guarantee that result will be free of cavitation.Furthermore, some intricate mold designs have alcoves that high viscosity mixes have trouble filling.The remaining 25-30 percent is generally some combination of admixture materials including but not limited to iron, silicone, limestone, and clay.The larger size of aggregate particles in conventional concrete also contributes to its overall pumpable yield stress.The finer aggregate particle sizes are one reason why SCC has a lower viscosity than conventional concrete without the need for more hydration.
