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.

葡萄糖酸钠与高能减水剂混合使用可以延缓混凝土的凝结时间，减少坍落度损失，提高混凝土的强度。

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.

经过多年的研发、生产及服务过程中总结了葡萄糖酸钠在混凝土中的应用方法：

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

1、使用葡萄糖酸钠，W/C比可以降低，这能使混凝土强度增加，这是一种优良型的混凝土。

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、大块和大重量的灌注工程是较难施工，由于加了葡萄糖酸钠，混凝土可操作性的改善力凝固时间的延缓能够避免结构上产生相接面，其结果能增进结构强度。

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、在炎热地区保持W/C比例不变而增进可操作性，在中东建造桥梁时曾用去大量葡萄糖酸钠。

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钠，能延缓凝固时间，这对长时间和高难度的灌注很为重要。

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

5、现在在混凝土工业中，预拌合混凝土是在中 心地点配套制好，然后用混合机卡车运送出去。在这种情况下，增加可操作性的延缓起始凝固时间很为重要。

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 强度和耐久性的混凝土，葡萄糖酸钠能用来达到此目的，这对高强度钢筋混凝土甚为重要。

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、预制的砌筑用砂浆一定要在长时间中可以使用，加入葡萄糖酸钠能延长工作期。

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

8、油井灌水泥浆，由于温度高是很难操作的，加入葡萄糖酸钠后泥凝土可以在170℃温度下工作几小时。

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.

近年来，小由于高层、高层建筑工程的建设，已不能由传统混凝土的施工技术满足其施工要求，发达地方泵送混凝土的使用已非常普遍，所以，减水剂和泵送剂等外加剂在工程中应用越来越广，所以对葡萄糖酸钠的供应量也就越来越大。

In recent years, due to the construction of high-rise and high-rise building projects, the traditional concrete construction technology can no longer 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.
