工業(yè)葡萄糖可增加混凝土的可塑性及凝固時間！

工業(yè)葡萄糖在現(xiàn)代的社會中真是隨處可見，工業(yè)葡萄糖的用途非常的廣泛，可以用于電鍍行業(yè)、玻璃清洗行業(yè)、污水處理、混凝土等行業(yè)。工業(yè)葡萄糖可增加混凝土的可塑性及凝固時間，我們都知道在工業(yè)活動中應(yīng)用葡萄糖酸鈉還是非常廣泛，特別是在一些建筑、紡織、污水處理等行業(yè)中更是發(fā)揮著重要的作用。在建筑工程中，主要是作為減水劑和緩凝劑來應(yīng)用的。那么，葡萄糖酸鈉在建筑工程中的混凝土發(fā)揮著怎樣的功效呢?
Industrial glucose can be seen everywhere in modern society. Industrial glucose is widely used in electroplating industry, glass cleaning industry, sewage treatment, concrete and other industries. Industrial glucose can increase the plasticity and setting time of concrete. We all know that sodium gluconate is widely used in industrial activities, especially in some construction, textile, sewage treatment and other industries. In construction engineering, it is mainly used as water reducer and retarder. So, what kind of effect does sodium gluconate play in the construction of concrete?
在水泥中添加一定數(shù)量葡萄糖酸鈉后，可增加混凝土的可塑性和強度，且有阻滯作用，即推遲混凝土的與終凝固時期。例如添加0.15%的葡萄糖酸鈉,可將混凝土的初凝固時間延長10倍以上,也就是將混凝土的可塑時間從幾小時延長幾天,而不影響其牢度。
Adding a certain amount of sodium gluconate to cement can increase the plasticity and strength of concrete, and has a blocking effect, that is, delaying the final setting period of concrete. For example, adding 0.15% sodium gluconate can extend the initial setting time of concrete by more than 10 times, that is, the plastic time of concrete can be extended from several hours to several days without affecting its fastness.
可塑性與延緩凝固時間在混凝土作業(yè)中是非常重要的問題，如在高溫度季節(jié)施工及大型的工程作業(yè)中，延緩凝固時間則是個難題，葡萄糖酸鈉可圓滿這個問題。另外高溫時膠接油井是比較困難的，添加了葡萄糖酸鈉后的混凝土在170℃高溫下，在幾個小時內(nèi)可塑，因此也能圓滿上述問題。
Plasticity and delayed setting time are very important problems in concrete operation. For example, delayed setting time is a difficult problem in construction in high temperature season and large-scale engineering operation. Sodium gluconate can successfully solve this problem. In addition, it is difficult to glue oil wells at high temperature. The concrete with sodium gluconate can be plastic in a few hours at 170 ℃, so the above problems can be solved successfully.
葡萄糖酸鈉用作混凝土外加劑具有以下有點：
Sodium gluconate as concrete admixture has the following advantages:
1、用葡萄糖酸鈉，W/C比可以降低，這能使混凝土強度增加，這是一種優(yōu)良型的混凝土。
1. With sodium gluconate, 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的。由于加了葡萄糖酸鈉，混凝土工作性的改善和凝固時間的延緩能夠避免結(jié)構(gòu)上產(chǎn)生相接面，其結(jié)果能增進結(jié)構(gòu)強度。
2. It is difficult to construct large block and heavy weight grouting project. Due to the addition of sodium gluconate, the improvement of concrete workability and the delay of setting time can avoid the occurrence of interface on the structure, which can improve the structural strength.
3、在炎熱地區(qū)保持W/C比不變而增進工作性有重要意義。
3. It is of great significance to keep the w / C ratio unchanged and improve the working performance in hot areas.
4、在混凝土拌合料中加入葡萄糖酸鈉，能延緩凝固時間，這對長時間和高難度的灌注很重要。
4. Adding sodium gluconate into concrete mixture can delay the setting time, which is very important for long-time and difficult pouring.
5、在現(xiàn)代的混凝土工業(yè)中，預(yù)拌合混凝土是在中 心地點配制好，然后用混合機卡車運送出去。在這種情況下，增加工作性和起始凝固時間甚為重要。
5. In the modern concrete industry, ready mixed concrete is prepared at a central location and then transported by mixer trucks. In this case, it is very important to increase the workability and initial solidification time.
