葡萄糖酸鈉可以做為摻合劑用在混凝土中，它在混凝土中的基本功能如下所示： 減水劑產(chǎn)品 和 緩凝劑。
葡萄糖酸鈉一般是直接應(yīng)用，可是還可以與其他緩凝劑如糖類(lèi)與碳水化合物和聚磷酸鹽配合起來(lái)應(yīng)用。葡萄糖酸鈉是一種結(jié)晶體的粉末狀。是在妥當(dāng)要求和操控的前提下制造下來(lái)的。此化學(xué)物質(zhì)是化學(xué)純的而且無(wú)腐蝕。品質(zhì)是不變的。這種特性能確保它在使用中有穩(wěn)定的和反復(fù)性的結(jié)論。葡萄糖酸鈉做為減水劑產(chǎn)品根據(jù)添加減水劑產(chǎn)品，混凝土水灰比（W/C）可以減少。
根據(jù)添加葡萄糖酸鈉可以得到如下所示的實(shí)際效果：
1、 提高工作中性。在混凝土水灰比（W/C）不會(huì)改變的情形下，添加葡萄糖酸鈉能提高工作中性。這時(shí)，葡萄糖酸鈉是起增粘劑的功效。在葡萄糖酸鈉補(bǔ)加在0.1%下列時(shí)，其改善工作中性 的水平與添加量正相關(guān)。
2、 提高抗壓強(qiáng)度。當(dāng)水泥含量保持一致而混凝土中的水含量可減少（即W/C降低）。當(dāng)葡萄糖酸鈉的添加量為0.1%時(shí)，加水流量可降低10%。
3、 減少水泥含量。水和水泥含量以同占比減少，W/C比保持一致。葡萄糖酸鈉做為緩凝劑葡萄糖酸鈉可以明顯減緩混凝土的凝固時(shí)長(zhǎng)。在使用量為0.15%下列時(shí)，開(kāi)始凝固時(shí)長(zhǎng)的對(duì)數(shù)與加配量成正比例關(guān)系，即配加量加一倍，初凝延遲時(shí)間到十倍，這就也就能工作中的時(shí)間段從非常少幾小時(shí)增加到幾日而無(wú)損于抗壓強(qiáng)度。 尤其是在天熱和必須擺放的時(shí)間較長(zhǎng)時(shí)，這也是一項(xiàng)至關(guān)重要的優(yōu)勢(shì)。
Sodium gluconate can be used as an admixture in concrete, and its basic functions in concrete are as follows: water reducer product and retarder.
Sodium gluconate is generally applied directly, but can also be used in combination with other retarders such as sugars and carbohydrates and polyphosphates. Sodium gluconate is a crystalline powder. It is manufactured under the premise of proper requirements and control. This chemical is chemically pure and non-corrosive. Quality is constant. This feature ensures that it has stable and repeatable conclusions in use. Sodium gluconate as a water-reducing agent product According to the addition of a water-reducing agent product, the concrete water-cement ratio (W/C) can be reduced.
According to the addition of sodium gluconate, the actual effect as shown below can be obtained:
1. Improve work neutrality. The addition of sodium gluconate can improve work neutrality without changing the water-cement ratio (W/C) of concrete. At this time, sodium gluconate acts as a thickener. When sodium gluconate supplemented below 0.1%, the level of improving work neutrality was positively correlated with the amount added.
2. Improve the compressive strength. The water content in the concrete can be reduced (ie W/C lower) when the cement content remains the same. When the addition amount of sodium gluconate is 0.1%, the water flow rate can be reduced by 10%.
3. Reduce cement content. The water and cement contents were reduced in the same proportion, and the W/C ratio remained the same. As a retarder, sodium gluconate can significantly slow down the setting time of concrete. When the usage amount is below 0.15%, the logarithm of the starting time of solidification is proportional to the added dosage, that is, the dosage is doubled, and the initial setting delay time is ten times, which means that the working time can be changed from very high. Increase from hours to days without compromising compressive strength. This is also a crucial advantage, especially in hot weather and longer periods of time when it has to be set up.
