如果您計劃建立本質上結構的任何東西，您需要將各種砌體綁在一起，或者您需要在砌體中進行一些修理，然後您可能非常需要的一件事是液壓水泥。現在，這是一個非常特別的建築材料，雖然你可能已經聽說過它，但你可能不知道它被用作什麼。
讓我們弄清楚液壓水泥是什麼，它使用的是什麼，以及它的優缺點是什麼。
什麼是液壓水泥？
In case you don’t know exactly what hydraulic cement is, this is a special type of cement with the main defining characteristic, which is the fact that it has the ability to cure when wet. This goes to the point where it can even cure when totally submerged under water.
For this reason, hydraulic cement is often used for buildings and structures that are often exposed to high levels of humidity and water, and especially for those structures that are often in contact with water.
Besides your normal substances found in cement, four other main components include alite, belite, celite, and brownmillerite. The first of those two ingredients allow for great hardness and strength when cured, and the latter two of those ingredients help to keep the hydraulic cement in its liquid state before it is used.
液壓水泥的優點
Now that we know exactly what hydraulic cement is, let’s figure out what its main advantages are and what it is useful for.
＃1：易於DIY
使用液壓水泥獲得的主要優點之一是您自己易於使用的事實。您可以在各種尺寸下購買一袋液壓水泥，然後用一點水混在一起混合。應用normal cement and mortar working toolsis also extremely easy. You generally just have to mix and apply as needed, which definitely isn’t too difficult.
＃2：理想的維修
關於液壓水泥也可以說的是，它是用於各種維修的理想選擇。如果您發現在您家的基礎上磚塊或小裂縫之間有鬆散的砂漿，那麼可以使用一點液壓水泥來填充它們。有了這一點，確實注意液壓水泥不是真正的結構聲音，所以你可以用這種類型的水泥做的修理類型限製。
當然，液壓水泥確實有許多其他用途，但就家庭維修而言，在煙囪，沙井，地下室牆上，遊泳池，基礎和排水係統工作，液壓水泥可以相當方便。
#3: Fast Setting Time
When it comes to building new structures and performing repairs, one of the biggest advantages that you get with hydraulic cement is the fact that it has an extremely fast setting time. Hydraulic cement will set in hard and within about three minutes after being mixed with water, which means that repairs can be performed extremely quickly. It’s a good repair material to use if you only have a limited amount of time to work with.
#4: Budget-Friendliness
If you need to perform small- or medium-sized repairs on your home, especially in masonry, then hydraulic cement is an extremely cost-effective solution to go with. It’s much cheaper to use a bit of hydraulic cement to make repairs than it is to jackhammer out whole sections of masonry and to replace them.
＃5：可控設置時間
液壓水泥的最酷方麵之一是您可以控製它的凝固時間，因為將冷水添加到它會減慢凝固時間，而向其添加熱水將大大加速設置時間。這種可調節性或可定製性是許多人肯定欣賞的重要優勢。
＃6：厚度好
What can also be said about hydraulic cement is that it is very easy to use thanks to the fact that it is fairly thick, so it does work for vertical applications. You can apply it for vertical applications, and it won’t immediately run down. It sets fast enough so that it is relatively unaffected by gravity.
#7: Being Waterproof
當然，使用液壓水泥獲得的最大優勢之一是防水的事實，這當然是為什麼它通常用於涉及與水恒定接觸的應用，例如沙井，排水係統和遊泳池。您甚至可以使用液壓水泥修複漏水管，而不會停止泄漏。
#8: Corrosion Resistance
Yet another advantage that you get with hydraulic cement is of course the fact that it is resistant to corrosion and rusting.
＃9：曾經治愈的工作
其他的如何ge that you get with hydraulic cement is the fact that you can actually paint over it once cured.
Disadvantages of Hydraulic Cement
Just like anything else out there, while hydraulic cement does have many advantages, it also has certain disadvantages.
#1: Susceptibility to Cold
使用液壓水泥獲得的最大缺點之一是它不適用於冷凍表麵，並且當溫度低於40華氏度時，它不會適當地固化。如果溫度在施用48小時內急劇下降，則應避免使用液壓水泥。
#2: Limited Working Time
雖然能夠在幾分鍾內設置和硬化是一個優勢，但在某些情況下，問題的事實是您確實使用液壓水泥曾經混合的液壓水泥工作非常迅速。如果您不夠快速工作，它將開始在您的容器中設置和硬化。
#3: Not Structural in Nature
Although this type of cement is useful for making repairs, it’s really not very structural in nature, which is why cement alone, in general, is never used for structural purposes.水泥用於製作混凝土，這就是用來構建結構的。
＃4：不債券混凝土
On that same note, if you happen to be fixing cracks in concrete, hydraulic cement is not the best option to go with because it doesn’t bond concrete together very well.
＃5：健康問題
此外，請記住，液壓水泥在呼吸中有毒，您應該避免接觸眼睛或皮膚。吸入液壓水泥中包含的二氧化矽可能導致肺問題。
5+ Hydraulic Cement Uses
Hydraulic cement can indeed be used for a wide variety of applications, so let’s take a quick look at what each of these is.
＃1：池
Hydraulic cement is often used in the construction and repair of swimming pools due to its waterproof nature.
#2: Drainage
Drainage systems are often made with masonry, but they do also break down, which means that waterproof hydraulic cement is the best choice for repairs.
#3: Foundations
Hydraulic cement is an ideal option to go with both for building and repairing foundations due to the fact that it can seal cracks and keep things watertight.
＃4：煙囪
雖然煙囪可能有時用砂漿構建，但由於其防水性質，它們通常也將液壓水泥融入其構造。煙囪當然暴露在元素中，這意味著液壓水泥是與之相處的理想選擇。
…和更多
液壓水泥也可用於許多其他應用，包括以下應用：
- Fountain building
- 各種海洋應用
- 密封混凝土周圍砌體
- Repairing and building manholes
- 用於密封和修理地下室牆壁

概括
As you can see, hydraulic cement is definitely quite a useful and user-friendly building and repair material. Although it may not be all that structurally sound, it does still have a variety of advantages and useful applications.
