Introduction
Iron cement plastering is a traditional construction method in China, which has been widely used in our country for more than 2000 years. Although its technical level is low, it still plays an important role in the construction industry. Iron cement plastering was first used to plaster earthen buildings and stone walls, which was able to improve the hardness of the walls, protect the buildings and make them more resistant to weather changes. With the development of modern construction technology, this technology has been improved, and its application range has expanded. The use of iron cement plastering has been extended to the fields of modern buildings and infrastructure construction.
Iron cement plastering is a construction method that uses a mixture of sand, cement, iron filings and other additives to form a plaster. The plaster applied on the wall is hardened due to the reaction between the iron filings and the other ingredients in the mixture. This is a fast and effective construction process, and also a relatively economical method for building construction.
The raw materials for the preparation of iron cement plaster are sand and cement. Cement is the main component of the mixture, and it plays an important role in the hardening process of the plaster. The amount of cement used in the mix is usually between 4-6%, depending on the type of sand used. Iron filings, which are ground and screened iron particles, are added to the mixture to act as a hardening agent. The amount of iron filings used in the mixture is usually between 15-30%. In addition to these basic components, additives such as lime, gypsum and slab can be added to the mix as binders and to improve the hardening process of the plaster.
The process of iron cement plastering is relatively simple. The mixture is first prepared by mixing all the components uniformly, and then it is applied to the surface of the wall. After the plaster has been applied, it should be left to harden for several days. During this period, the iron filings will react with the other components in the mixture, and the plaster will become harder and stronger.
While iron cement plastering is a rather simple process, proper application is essential to get the desired result. The wall should be well prepared before the plaster is applied. All the cracks, pores and other imperfections should be sealed with a suitable material to minimize the risk of water leakage. The iron cement mixture needs to be applied in the correct amount, taking into account the shape of the wall. After the plaster has been applied, it should be left for at least four days so that it has time to reach its maximum strength.
In conclusion, iron cement plastering is a simple and economical construction method, which is often used in modern buildings and infrastructure construction. It is relatively easy to apply, although proper preparation is necessary to achieve the desired strength. This method of plastering is cost effective and requires minimal maintenance. It is also environmentally friendly, as the waste material which is produced can be recycled or reused.
