Types of building cement
To build various buildings, including a small apartment or even towers, practical materials must be used, one of the most important materials is cement, which is an integral part of a construction. There are different types of cement that are used in building roads and dams in addition to building an apartment. Cement is one of the materials that plays a prominent role in the construction of a building. This product is made from a combination of materials such as lime, clay, silica and mineral oxides at a temperature of about 1500 degrees Celsius. Cement is a substance that creates a resistant mixture with water and becomes hard. Various types of construction cement are used as an adhesive mortar.
Construction cement consists of different types that we mention in this section:
Portland Cement
Portland cement is one of the common powder cements available in the market, which is used in construction that does not require high strength. In fact, it can be said that this cement is mostly used for general purposes. Portland cement is effective in structures that do not need to bear a lot of load. For example, this cement can be used in the construction of street tables, cement pipes for water transmission, construction of sidewalks, and many other things that are built normally. When using, they combine Portland cement with sand and use the prepared mortar.
Benefits of Portland Cement
- مقاوم در برابر شرایط مختلف آب و هوایی
- مقاومت در برابر ترک خوردگی و تخریب
- مقاومت در برابر سولفات آب یا خاک
- قابلیت استفاده در مکانهای مرطوب
- محدودیت واکنش با آب
- مقاوم در برابر سفیدک و شوره
- از لحاظ هزینه مقرون به صرفه
- وجود خاکستر فلزی در متریال و کارایی راحت
Cement mixed
As it is clear from the name of this product, this type of cement is created from the combination of different materials such as pozzolan, slag and lime. The compounds in this cement have caused it to be modified compared to other products. Different cements used in the building have different uses, which are used according to the characteristics of the material that makes it.
Pozulani cement
Pozzolan is a material consisting of silicate and is similar to cement in terms of its constituent materials. Pozzolan plus Portland cement produces blended cement. 15% of mixed cement consists of pozzolan. The characteristics of this cement include strength against sulfate, low temperature and optimal hydration speed. Pozzolanic cement is used for concreting in large volume and in tropical regions.
Benefits of Pozulani cement
- سیمان پوزولانی سبب افزایش مقاومت بتن میشود.
- متراکم بوده و در برابر مواد شیمیایی مقاوم است.
- در شرایط نامساعد جوی در برابر یخ زدگی و گرمای شدید دوام دارد.
- در برابر رطوبت نفوذناپذیر است.
- میزان سیمان استفاده شده در تولید بتن را کاهش میدهد.
- احتمال ترک خوردن بتن را کاهش میدهد.
- از عواملی که سبب خوردگی در میلگرد میشود، کم میکند.
Limestone cement
Cement
Overhead cement is a type of construction cement that has a very uniform texture. The amount of overburden in cement varies from 25% to 70%. The particles of this type of cement are smaller than the normal type and it is used in marine structures. Overburden cement is resistant to sulfates in water or soil. (second obituary)
Aerona Cement
Aerated cement is one of the construction cements that can be used in cold regions due to its resistance to freezing. Water increases in volume as a result of freezing, and this cement takes into account this change in volume during construction and provides enough space. Aerated cement helps strengthen concrete and is resistant to cement cracking
White cement and colored cement
In addition to the things mentioned above, it can be said that the most popular type of construction cement in the market is white and colored cement. This type of cement is classified as Portland cement. The color stability of this type of cement has led to its use in building facades. This product is resistant to sunlight and does not change. This type of cement increases the speed of construction.
Many cements have flaking properties and cannot be used in the facade of the building, but colored cement is an exception to this and due to their high quality, they can be used in the facade of the structure. This type of cement is readily available and cost-effective. In addition to these advantages, white and colored cement also has disadvantages such as long-term pollution absorption, lack of insulation against moisture, and cracking over time.
Application of all kinds of cement in the building
The use of cement is very wide, which we briefly mention in this section:
- ساخت انواع ستون برای ساختمانها
- استفاده از سیمان در ساخت جداول
- استفاده در نمای سازه
- استفاده از سیمان رنگی در تزئین سازه بتنی
- ساخت انواع پل
- طراحی تونلهای جادهای
- استفاده از انواع سیمان برای فونداسیون
- استفاده از انواع سیمان در دیوارههای سازه
- استفاده از سیمان برای سدسازی
- استفاده از سیمان در خطوط انتقال آب
- کارایی در ساخت لولههای فاضلاب
