  Overview of foam concrete Foamed concrete  is a foaming agent that is fully foamed mechanically by the foaming system of the foaming machine, and the foam and cement slurry is evenly mixed. Then use the foaming machine pumping system for cast-in-place construction or mold forming, and a new type of lightweight thermal insulation material formed by a large number of closed-cell thermal insulation materials. As a new type of energy-saving and environmentally-friendly building material, scholars at home and abroad have conducted a lot of research and development on it, making it widely used in wall materials. Advantages: low density, lightweight, good heat insulation, sound insulation, and seismic performance. 1. Cement ratio The main raw material of foamed concrete is cement. Since foamed concrete is mostly cured at room temperature and a large amount of foam is added, these two factors determine its higher cement ratio. This is fundamentally different from aerated concrete. B...

  Overview of superplasticizer The superplasticizer  can significantly improve the fluidity of the mixing slurry so that the foam mud can reach self-leveling in the mold and reduce or even no bread. It can greatly reduce water consumption while maintaining the slump of concrete. Water reducer is also known as dispersant or plasticizer, and it is the most commonly used admixture. The principle of water reducing agent, the specific surface area of cement is generally 350-400m2/kg, and more than 90% of cement particles have a particle size in the range of 7-80 microns, which belongs to the category of fine powder particles. For cement-water systems, the surfaces of cement particles and hydrated cement particles have a slightly polar surface and are highly hydrophilic. Fine cement particles have considerable specific surface energy (solid-liquid interface energy). In order to reduce the total heat on the surface solid and liquid, fine cement particles tend to spontaneously condens...

  Aerogel overview Aerogel  is a solid material form, the smallest dense solid in the world. The density is 3 kilograms per cubic meter. The most common aerogel is silicon aerogel, which was first made by American scientist Kistler in 1931 because of a bet with his friends. There are many types of aerogels, including silicon, carbon, sulfur, metal oxide, metal, and so on. Aerogel is a compound word, where aero is an adjective, which means flying, and gel is obviously a gel. Literally means a flying gel. The gel of any substance can be called an aerogel as long as it can be dried and removed from the internal solvent, but can basically keep its shape unchanged, and the product has high porosity and low density. Because of its extremely low density, the lightest aerogel is only 0.16 mg per cubic centimeter, which is slightly less dense than air, so it is also called "frozen smoke" or "blue smoke." Since the particles inside are very small (on the order of nanometers),...

  Overview of polycarboxylic acid water reducer Polycarboxylic acid superplasticizer  is a powdery polycarboxylic acid superplasticizer prepared by a new process. It has an excellent comprehensive index, good dispersibility, high water reduction rate, good adaptability to various cement, and no green Pollution, and other advantages. It is a high-performance environmentally friendly product. The polycarboxylic acid superplasticizer powder of this product accounts for 0.16-0.3% of the total amount of gelling materials, and the water reduction rate is> 25%. The polycarboxylic acid superplasticizer does not contain harmful ingredients and does not pollute the environment. No chlorine, low alkali. Product advantages 1. It has good compatibility with various cement, and the slump retention performance of concrete is good, which prolongs the construction time of concrete. 2. Low dosage, high water reduction rate, and low shrinkage rate. 3. Significantly improve the early and late ...

  Synthetic blowing agent overview The synthetic foaming agent  used for concrete is a highly concentrated and efficient liquid used to produce lightweight foamed concrete. Foamed concrete is also called foamed lightweight concrete (CLC). CLC concrete has great potential in the construction of honeycomb lightweight applications, and the use of the correct type of foaming agent will make a huge difference in product properties (such as the mechanical properties of concrete and its resistance, etc.). Synthetic foaming agents are chemical substances that reduce the surface tension of liquids and are widely used in the manufacture of blocks, bricks, CLC concrete, etc. worldwide. Compared with other foaming agents, it can be formed with less energy when high density is required. It is strongly recommended for use in the construction industry, as the demand for lightweight concrete continues to increase over time. Foamed concrete  is a mixed gel of various materials and admixtu...

 Overview of concrete waterproof admixture: A concrete waterproof admixture is a chemical admixture added to the cement. After the cement is hardened, its volume will expand to compensate for the shrinkage and tension of the steel bars, thereby generating prestress and completely filling the cement gap. It can be directly incorporated into the bottom surface of the cement waterproofing agent product to form an excellent hydrophobic layer. When water splashes on the surface, it will roll off in the form of water droplets, acting as a lotus leaf. The mixture of water and foam is called a pre-foaming solution. The pre-foaming solution and compressed air are supplied through a spray gun. What is a concrete waterproofing agent? A concrete waterproof additive is a kind of chemical admixture added to the cement. When the cement solidifies and hardens, the volume expands and plays a role in compensating for shrinkage and tensioning the steel to generate prestress and fill the cement gap. W...
