Civil engineering is a branch of study that focuses on the design, construction, and maintenance of various types of infrastructure, including roads, bridges, and dams. Civil engineers are involved in the development process from the beginning. Civil engineering programmes often focus on the construction, design, and maintenance of infrastructure.

Aggregate Crushing Value (ACV) The aggregate Impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from its resistance to a slowly applied compressive load. With aggregate of aggregate impact value higher than 30 the result may be anomalous.

As per the British standards, concrete is capable of carrying a strain up to 0.0035 and steel starts yielding at a strain of 0.002 and it can increase greater than the concrete. When the axial stress exceeds a certain amount resulting in concrete strain grater than 0.0035 concrete will fail suddenly. It will be a sudden crushing of concrete.

Make sure the fresh concrete is mixed frequently. 3. Make sure the weighing is set to zero. (Ashikin Mastura 23859) By carrying out this experiment, we were able to determine the production of concrete mixing. the first step into making the concrete is batching of materials.

The most important parameters associated with recycled concrete aggregate (RCA) production that may affect quality and yield include such properties of the parent concrete as the composition, strength and aggregate grading, type of crushers used, number of crushing stages, the size of the RCA particles, and the size reduction sequence.

So we generally don''t depend on concrete in tension, and cracking is not considered ''failing''. Crushing, on the other hand, does amount to failure. In bending elements, we want the ultimate failure mechanism to be yielding of steel rather than crushing of concrete, as that is a much more ductile failure mode.

Compressive Strength Test Idea: 1- Concrete is poured in the mould and compacted properly to reduce the amount of voids. 2- After 24 hours, moulds are removed and test specimens are then placed in water for curing. 3- After the specified curing period [3, 7, 28, 56, or 91 days], specimens are tested by the compression testing machine.
