For those who are not limited by the construction site and material supply or who build their own houses, self mixing concrete construction can also be selected. However, after selecting the self mixing form, a more careful construction team with higher quality should be recruited for construction, because the strength of concrete still depends on manual adjustment. The material selection must be the material with less mud content, and the cement grade above 42.5 should be used as far as possible (determined by the concrete strength requirements), After self mixing, pouring and tamping, the necessary work is the second vibration and the second plastering. Therefore, the selection of self mixing concrete should adhere to the following principles: selecting the right weather for construction, the right construction team, using the right materials, and the construction process.
For restricted conditions or mandatory (especially urban engineering) requirements, commercial concrete construction must be selected, and commercial concrete companies with good reputation must be selected as partners. For site construction personnel, they must go to the site to determine the materials before each material demand. If the mud content is too large, commercial concrete companies can be required to carry out targeted mix design again.
Adhere to the slump monitoring of each truck of concrete, do not adjust the water consumption on site, and reasonably allocate the concrete supply speed according to the number of construction workers, pouring and tamping speed and weather conditions. If the concrete slump on site is too high, it can be returned or poured into the entity. The maintenance of concrete after pouring and tamping is very important, because the commercial concrete is extremely not thirsty, and all admixtures must stabilize its performance through water, Selection of commercial concrete: select the right supply company, check every vehicle every time, the construction process is indispensable, and the maintenance should be in place.
Self mixing concrete itself has its advantages, so we still use it today, but also has its disadvantages, so we have carried out selective use; Commercial concrete itself has its advantages, so we have carried out it in a large area, but also has its disadvantages, so we must correct it; In the actual construction, the construction unit bears most of the responsibility. The market prospect must be commercialization and marketization to cooperate with the construction, and the implementation of commercial concrete is not long, and it is also in constant improvement. In the actual construction, as the user unit, we should adhere to the principles and not be careless, so as to promote the healthy development of commercial concrete and bring power to the process of urbanization. The law of the market is that high production efficiency will replace low production efficiency.
