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.

對(duì)于受條件限制或是強(qiáng)制性（特別是市區(qū)工程）要求那就必須選擇商品砼施工，選擇信譽(yù)較好的商品砼公司作為合作伙伴，對(duì)于現(xiàn)場施工人員每次需料前必須前往現(xiàn)場確定材料，如果含泥量偏大可要求商品砼公司重新進(jìn)行針對(duì)性的配合比設(shè)計(jì)。

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.

堅(jiān)持每車砼進(jìn)行坍落度監(jiān)測，不得在現(xiàn)場調(diào)整用水量，根據(jù)施工人數(shù)、澆搗速度以及天氣情況合理調(diào)配砼供應(yīng)速度，如果現(xiàn)場出現(xiàn)砼坍落度偏可退回也不可澆入實(shí)體中，砼澆搗后養(yǎng)護(hù)至關(guān)重要，因?yàn)樯唐讽艠O不耐渴，所有的外加劑必須通過水份來穩(wěn)定它的性能，選擇商品砼堅(jiān)持：選合適供應(yīng)公司、每次每車堅(jiān)持查看、施工工序不可少、養(yǎng)護(hù)要到位。

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.

發(fā)展前景：

Development prospects:

自拌砼本身有它的優(yōu)點(diǎn)所以我們沿用至今，也有它的缺點(diǎn)所以我們已進(jìn)行選擇性的使用；商品砼本身有它的優(yōu)點(diǎn)所以我們已大面積的推行，也有它的缺點(diǎn)所以必須去改正；而在實(shí)際施工中施工單位承擔(dān)了大部份責(zé)任。對(duì)于市場前景也必是商品化和市場化來與建筑施工相配合，而商品砼推行時(shí)間并不長而且本身也在不斷的改進(jìn)中，在實(shí)際施工中做為使用單位我們應(yīng)堅(jiān)持原則做事，不得馬虎，這樣才能推動(dòng)商品砼的良性發(fā)展，給城市化進(jìn)程帶來動(dòng)力。市場規(guī)律也必是生產(chǎn)效率高來取代生產(chǎn)效率低的生產(chǎn)模式。

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.
