In the age of money and land, people are used to changing the housing structure to increase the living space. One house becomes two houses, and two houses become three houses. This requires new walls to achieve. What are the materials of the new wall? What are their advantages and disadvantages?
First of all, what are the commonly used materials for new walls?
Since the building walls are built based on scientific calculation, if you want to add a wall with large volume and weight, you need the approval of the original design unit and the property management unit of the house. Therefore, when building new walls, Metropolis will choose to build new lightweight walls. There are three main types of lightweight walls: brick walls, skeleton partitions, and finished wall panel partitions. Such walls have excellent fireproofing, moisture-proof and sound insulation effects. The main thing is that the wall is light in weight and does not bear any weight or increase the bearing capacity of the house, so the stability of the house will not be damaged.
1. Light brick partition
As the name suggests, light brick partition wall is a wall built with light brick. Due to different soil properties and manufacturing processes, light brick can be divided into clay hollow brick, clay porous brick, concrete hollow brick, ceramsite brick, expansion aerated concrete brick, etc. Among them, expansion aerated concrete brick is commonly used in home decoration.
2. Skeleton partition
The skeleton partition wall uses light steel keel or wood keel as the skeleton, filled with filler, and then attached with gypsum board or asbestos cement board on both sides of the keel. The filler inside the wall varies with the external plastering. If the gypsum board is the surface, the gypsum slurry is filled inside. The skeleton partition of the gypsum wall is slightly higher in fire resistance and stress. If asbestos cement board is selected, the interior shall be filled with cement. The light partition formed in this way has the characteristics of fire prevention, moisture resistance and impact resistance.
3. Gypsum block partition
Gypsum brickwork is a kind of light wall material with fire prevention, moisture-proof and sound insulation effects. It can be sawed, nailed, drilled and easy to construct.
The mixing of cement, lime, gypsum and other inorganic cementing materials with water makes the concrete mixture plastic; The strength is then produced through chemical and physicochemical action, condensation and hardening. Generally speaking, drinking water can meet the requirements of concrete mixing water. Excessive acid, alkali, salt and organic matter in water will have harmful effects on concrete. The aggregate not only has the filling function, but also has an important influence on the properties of concrete such as bulk density, strength and deformation.
Admixtures can be added to improve some properties of concrete. Due to the obvious technical and economic effects of admixture, it has increasingly become an indispensable component of concrete. In order to improve the workability of concrete mixture or the performance of hardened concrete and save cement, finely ground mineral materials - admixtures can also be added during concrete mixing. It can be divided into active and inactive categories. The nature and quantity of admixtures, influence Sand aerated block Strength, deformation, hydration heat, impermeability, color, etc.
