Its artistic effect can bring audience interest and formal beauty. Combination method of cobblestone and text: cobblestone is a good carrier of text, and the text is integrated with the cobblestone through the writing of calligrapher, forming a landscape stone by itself. In classical gardens, calligraphy can not only awaken the artistic conception of gardens, but also is an independent aesthetic object. In the modern environment, the combination of pebbles and calligraphy can also play this role. But it should be noted that the style of calligraphy should be commensurate with the atmosphere and style of the environment, or be vigorous and dignified, or elegant and beautiful, and be written according to the scenery. Comprehensive application method: In landscaping, pebbles are often combined with water, trees, grass, soil, etc. to simulate nature to condense and enhance the natural environment to achieve the purpose of landscaping.


After ordinary concrete is mixed with an expansion agent, the concrete expands appropriately. Under the constraints of the steel bar and the adjacent position, a certain pre-compression stress can be established in the reinforced concrete structure. This pre-compression stress can roughly offset the dry concrete produced during the hardening process. Shrinkage stress and compensation of temperature difference stress caused by part of the heat of hydration, thereby preventing or reducing harmful cracks in the structure. It should be pointed out that the expansion agent mainly solves the early dry shrinkage cracks and the temperature difference shrinkage cracks caused by the mid-term heat. It is difficult to solve the temperature difference shrinkage caused by the later weather changes and can only be controlled by reinforcement and structural measures. Therefore, the expansion agent is most suitable for underground, hydraulic, tunnel and other projects where the environmental temperature difference is small. For structures with large temperature differences (roofing, floor slabs, etc.), corresponding structural measures (post-pouring zone) must be taken to control cracks.

Relevant standards The national standard "Limits of Radionuclides in Building Materials" promulgated in 21 years is divided into three categories according to the radioactivity level of decoration materials: The radioactivity of the natural radionuclide radium-22thorium-23 potassium-4 in the decoration materials of Class A decoration materials The specific activity meets the requirements of IRa≤1. and I≤1.3 at the same time as Class A decoration materials. The scope of production, marketing and use of Class A decoration materials is not restricted. Class B decoration materials that do not meet the requirements of Class A decoration materials but also meet the requirements of IRa≤1.3 and I≤1.9 are Type B decoration materials. Class B decoration materials cannot be used on the interior surfaces of Class I civil buildings, but can be used on the exterior surfaces of Class I civil buildings and the interior and exterior surfaces of all other buildings.


Additives like this are generally implemented for local information guidance prices during the construction period, and temporary sub-items can be added to the cost software.


How to use:


1. 1. Before use, it is generally diluted with 3-10 times tap water, and the specific dilution ratio needs to be determined according to the complexity of the product and the actual situation.


2. Except for water, please do not add any other additives to the concentrate.


3. On the pre-treated or cleaned mold, spray the release agent 3-5 times under normal processing temperature to ensure that the mold has a uniform release mold formation.


4. 4. Each spray can be demoulded 5-10 times.


Store:
After use, please cover the barrel tightly and keep the barrel in a cool place.

The cause of the formation of stone freeze-thaw freeze-thaw phenomenon mainly occurs in colder places near the north and other places. When the pores of the stone absorb enough water, once the temperature drops below ℃, the water in the stone begins to freeze and the volume expands. When the expansion force of the ice is greater than the structural force of the stone, the stone will be broken. This is the freeze-thaw phenomenon. Generally speaking, substances follow the law of thermal expansion and contraction, while water is the opposite. When the density of water is 4°C, water molecules move independently with mobility. When the temperature of water decreases from 4℃ to ℃, the water molecules in the ice are arranged in a three-dimensional pattern into an unusually loose form. This structural form actually leaves many cavities, but the density decreases.


Waterproof paint is better. If the pipes are irregular when coils are used, it will increase the difficulty of construction of the tarp, and the tarp will not have adhesive force, and it is easy to cause water penetration and leakage in the humid environment of the toilet. It not only reduces the waterproof effect, but also affects the aesthetics of the entire waterproof layer of the bathroom. If the waterproof coating is used, the operation is simple and convenient, and the waterproof performance is very good.
