When decorating housing projects, there is one thing that can be said to be the foundation and an important link, that is, cement, cement is an important raw material for the composition of the house, and it is also an indispensable material for decoration. There are many kinds of cement, so today we will introduce to you the difference between self-leveling cement and ordinary cement and what are the characteristics of self-leveling cement.
1. The difference between self-leveling cement and ordinary cement
1. Self-leveling cement has the characteristics of automatic leveling, and the construction of self-leveling cement only needs to be scraped in batches with a special tooth scraper, and it is easy for a completely inexperienced worker to get started.
Ordinary cement does not have this characteristic, and construction also requires a professional cement worker. The traditional cement mortar leveling ground needs to reach a certain thickness to ensure that it is not easy to rise, sand, and hollow, generally at least 25-30mm thick.
2. Self-leveling cement dries faster than ordinary cement, and under normal circumstances, after the construction of self-leveling cement 24, you can start to install ground decoration materials.
Ordinary cement requires a curing period of one to two weeks to meet the requirements of drying.
3. Self-leveling cement can be 1mm without cracking, and the hardness is greater than that of ordinary cement.
4. Self-leveling cement is based on cement plus other formulas, and the price of self-leveling cement is much more expensive than ordinary cement.
5. Self-leveling cement does not increase the elevation, which can save space and reduce ground load-bearing.
6. Self-leveling cement is a dry-mixed powder material composed of a variety of active ingredients, which has a wide range of uses, and can be used in industrial plants, workshops, warehousing, commercial stores, exhibition halls, gymnasiums, hospitals, various open spaces, offices, etc., and is also used in homes, villas, warm small spaces, etc., which can be used as a finishing surface layer and a wear-resistant base layer.
Second, what are the characteristics of self-leveling cement?
1. Self-leveling cement is a kind of special cement, which contains many other raw materials, has strong fluidity, can be automatically leveled, generally made of 2 mm thick, mainly used in PVC floor laying, generally used for the bottom layer. Self-leveling ground is made of material water, can be turned into a free-flowing slurry, according to the uneven terrain, can be quickly expanded on the ground, so as to obtain a high flatness of the floor.
2. Self-leveling cement is a dry-mix powdery material, which can be used by mixing water on site. Slightly unfolded with a scraper, a highly flat base surface can be obtained. The hardening speed is fast, and you can walk on it in 4~8h, or carry out follow-up projects, and the construction is fast, safe, pollution-free and beautiful.
3. Low bulk density ratio of cement-based self-leveling, the traditional cement-based self-leveling is generally 1.5 kg for one square meter and one millimeter thickness, and if it is three millimeters thick, 25 kg/bag, about 5.5 square meters.
The above is to introduce to you today about the difference between self-leveling cement and ordinary cement and what are the characteristics of self-leveling cement, cement is an important product in building materials, brands are also countless, although the characteristics of self-leveling cement are different from ordinary cement, but there are also many brands, in order to choose a good product from it, you need to carefully screen.
