The following precautions should be taken during the preparation of good quality concrete:
To build up a quality, durable and strong structure, the concrete that is used should contain standard quality. A good quality concrete should be stable, condensed, workable and cost-effective.
The following properties should be maintained to produce a good quality concrete

The following properties should be maintained to produce a good quality concrete
- The quality of aggregate should have been rigid and long-lasting.
- The grading of the aggregates should be done perfectly and consistently.
- Adequate quantities of cement should included in concrete to maintain necessary strength and water-resistance capability.
- The water does not contain any organic or deleterious materials.
- The quantity of water should be maintained in such a manner so that the uniformity is retained properly.
- The proportion of water-cement should keep as minimum as possible.
- To keep up conformity, mixing of concrete should be performed systematically.
- To eliminate air bubbles and voids, the freshly arranged concrete should be compacted properly.
- While transmitting the concrete to the job site, no segregation of or separation of materials should happen in concrete.
- Concrete that is provided at the point of placing should have been homogeneous & contain right symmetry.
- Ensure that the concrete is not thrown from a distance of high point to prevent segregation.
- Curing of concrete should be done perfectly for minimum 28 days.
- The temperature of concrete should be retained over the freezing point unless it gets rigid enough.
- It should be stored in even horizontal layer having invariable thickness. Concrete should fill each section in this form.
