Self consolidating concrete properties
The demolished concrete could be recovered and used as cement raw meal to produce new cement clinker.
The concrete was also prepared by using these aggregates.
On the basis of the experimental results of the specimens of six sets of mix proportions, the mechanism of action of polypropylene fiber on compressive strength, flexural strength and flexural modulus of elasticity has been analyzed in details.
The most common method of consolidation is vibration and proper vibration of concrete ensures that the concrete is consolidated around the reinforcement and in the corners of the formwork.
If the fresh concrete is allowed to harden without consolidation, then the resulting hardened concrete tends to be non-uniform, weak, porous, and poorly bonded to the reinforcement.
Concrete, a composite material composed of cement, water, sand, and gravel, the world’s most widely used construction materials.
In 2003, more than 110 million metric tons of cement were consumed in the United States (U. Department of the Interior 2004), hence it is important to understand the properties of concrete in order to ensure safe and durable structures.
