Factory internship report content
1. Prevent the temperature difference between the inside and outside of the concrete and the gradient of the concrete surface to prevent surface cracks.
2. To prevent concrete from being super cold, we should try our best to ensure that the lowest temperature during the construction period of the concrete is not lower than the stable temperature during the service life of the concrete.
3. Prevent the old concrete from being overcooled to reduce the constraints between the new and old concrete. From a theoretical analysis, the moisture contained in newly poured concrete can fully meet the requirements of cement hydration and is more than enough. However, water loss often occurs due to evaporation and other reasons, thereby delaying or preventing the hydration of cement. Surface concrete is most easily and directly affected by this adverse effect. Therefore, the first few days after concrete pouring are the critical period for curing, and should be paid attention to during construction.
Therefore, we must handle these incidents carefully during construction and handle them differently according to different situations. These issues should be paid attention to during construction. What kind of cement should be used during construction and the amount should be paid attention to, as well as the early maintenance of the concrete.
