When it comes to sodium gluconate, knowledgeable friends know that it can improve the strength of building concrete, save energy and environmental protection, and has a wide range of uses.

葡萄糖酸鈉與高能減水劑混合使用可以延緩混凝土的凝結(jié)時(shí)間，減少坍落度損失，提高混凝土的強(qiáng)度。

The mixing of sodium gluconate and high-energy water reducer can delay the setting time of concrete, reduce the slump loss and improve the strength of concrete.

經(jīng)過多年的研發(fā)、生產(chǎn)及服務(wù)過程中總結(jié)了葡萄糖酸鈉在混凝土中的應(yīng)用方法：

After years of R & D, production and service, the application methods of sodium gluconate in concrete are summarized:

1、使用葡萄糖酸鈉，W/C比可以降低，這能使混凝土強(qiáng)度增加，這是一種優(yōu)良型的混凝土。

1. Using sodium gluconate, the w / C ratio can be reduced, which can increase the strength of concrete, which is an excellent type of concrete.

2、大塊和大重量的灌注工程是較難施工，由于加了葡萄糖酸鈉，混凝土可操作性的改 善力凝固時(shí)間的延緩能夠避免結(jié)構(gòu)上產(chǎn)生相接面，其結(jié)果能增進(jìn)結(jié)構(gòu)強(qiáng)度。

2. Large and heavy pouring works are difficult to construct. Due to the addition of sodium gluconate, the operability of concrete is improved, and the delay of setting time can avoid the contact surface on the structure, which can improve the structural strength.

3、在炎熱地區(qū)保持W/C比例不變而增進(jìn)可操作性，在中東建造橋梁時(shí)曾用去大量葡萄糖酸鈉。

3. Keep the w / C ratio unchanged in hot areas to improve operability. A large amount of sodium gluconate was used in the construction of bridges in the Middle East.

4、在混凝土拌合料中加入葡萄糖酸鈉，能延緩凝固時(shí)間，這對(duì)長時(shí)間和高難度的灌注很為重要。

4. Adding sodium gluconate into the concrete mixture can delay the setting time, which is very important for long-time and difficult pouring.

5、現(xiàn)在在混凝土工業(yè)中，預(yù)拌合混凝土是在中 心地點(diǎn)配套制好，然后用混合機(jī)卡車運(yùn)送出去。在這種情況下，增加可操作性的延緩起始凝固時(shí)間很為重要。

5. Now in the concrete industry, ready mixed concrete is prepared at the central location and then transported out by mixer truck. In this case, it is important to delay the initial solidification time by increasing operability.

6、降低W/C比能制成更高強(qiáng)度和耐久性的混凝土，葡萄糖酸鈉能用來達(dá)到此目的，這對(duì)高強(qiáng)度鋼筋混凝土甚為重要。

6. Reducing w / C ratio can make concrete with higher strength and durability. Sodium gluconate can be used to achieve this purpose, which is very important for high-strength reinforced concrete.

7、預(yù)制的砌筑用砂漿必須要在長時(shí)間中可以使用，加入葡萄糖酸鈉能延長工作期。

7. The prefabricated masonry mortar must be used for a long time, and the addition of sodium gluconate can prolong the working period.

8、油井灌水泥漿，由于溫度高是很難操作的，加入葡萄糖酸鈉后泥凝土可以在170℃溫度下工作幾小時(shí)。

8. When the oil well is filled with mud, it is difficult to operate due to high temperature. After adding sodium gluconate, the mud concrete can work at 170 ℃ for several hours.

近年來，小由于高層、超高層建筑工程的建設(shè)，已不能由傳統(tǒng)混凝土的施工技術(shù)滿足其施工要求，發(fā)達(dá)地方泵送混凝土的使用已非常普遍，所以，減水劑和泵送劑等外加劑在工程中應(yīng)用越來越廣，所以對(duì)葡萄糖酸鈉的供應(yīng)量也就越來越大。

In recent years, due to the construction of high-rise and super high-rise building projects, the traditional concrete construction technology can not meet its construction requirements. The use of pumped concrete in developed areas has been very common. Therefore, admixtures such as water reducer and pumping agent are more and more widely used in projects, so the supply of sodium gluconate is more and more large.
