In the process of building a work, engineering Proper maintenance of concrete<\/strong> It is an issue that many people are interested in. Construction quality is still the top concern of homeowners, in which the quality of concrete is a key factor to get a quality house. Many times the quality of materials (cement, sand, gravel, stone) meets the standards, but still does not give the desired quality of concrete. That can happen due to not following the correct preparation procedures such as placing concrete formwork. An equally important reason is not paying attention to the maintenance stage.<\/span><\/p>\n

The importance of maintenance <\/strong><\/span>concrete properly\u00a0<\/strong><\/span><\/h2>\n

Even though the concrete is well-graded, if the curing process does not comply with the technical requirements, the concrete cannot be of good quality. The quality of concrete is only achieved when it sets in a humid and impact-free environment. Therefore, concrete must be kept moist for as long as possible after pouring. Even though the concrete has hardened, even on the outside, the hydration process continues to achieve maximum concrete strength. In a too dry environment, the water in the concrete evaporates quickly, there is not enough water left for the hydration process, the concrete strength may stop growing and cause cracking. Ambient temperature is also an important issue. At normal temperature about 20o<\/sup>C to 30o<\/sup>C, cement hydrates slowly but at high temperature above 40o<\/sup>C, the rate of hydration increased significantly. Therefore, people can cure concrete with hot water from 80o<\/sup>C to 90o<\/sup>C. The faster the curing speed, the more pronounced the intensity of development in the early stages, only after 20 hours can reach the strength of 28 days.<\/span>
\nThrough techniques Proper maintenance of concrete<\/strong>, one can keep the concrete wet in many ways such as leaving the formwork intact, spraying water, soaking in water (for large surface surfaces such as roof decks), covering with tarps to protect against sunlight. Part of the concrete is unevenly dry, easily leading to the phenomenon of crow's feet cracking, concrete cracking, which is the cause of later seepage and infiltration.<\/span><\/p>\n

1. Do the face again for the 2nd time<\/strong><\/span><\/p>\n

\u2013 After the concrete is shaped and begins to harden (about 2-3 hours after placing the concrete), rub the concrete surface again so that the tensile stresses caused by the concrete shrinkage are destroyed (This is the first step). definitely important to do).<\/span><\/p>\n

2. Initial maintenance:<\/strong><\/span><\/p>\n

\u2013 Coating the concrete surface with materials that have been moistened to keep the concrete from losing water under the influence of climatic factors (such as: sun, wind, temperature, air humidity) is the first step. fairy of Proper maintenance of concrete<\/strong>,. Carry out initial curing as follows: After being formed, the concrete is immediately covered with moistened sheets of material (such as sacks, nylon sheets, canvas, etc.) At this time, do not water to prevent the concrete from being damaged by water because it does not have enough necessary strength, and does not collide strongly with the concrete.<\/span>
\nThe face covering lasts about 5 to 6 hours. In the field, this time can be determined by <\/span><\/p>\n

In the process of building a building, there are many things to pay attention to. Construction quality is still the top concern of homeowners, in which the quality of concrete is a key factor to have a "healthy" home. Many times the quality of materials (cement, sand, gravel, stone) meets the standards, but still does not give the desired quality of concrete. That can happen due to not following the correct preparation procedures such as placing concrete formwork. An equally important reason is not paying attention to the maintenance stage.<\/span><\/p>\n
