When the same polycarboxylic acid sloughing agent is used but different cement is used, it is possible that this polycarboxylic acid sloughing agent has good compatibility with one kind of cement but poor compatibility with another cement, and when u…
Polycarboxylate superplasticizer is the third generation of high performance superplasticizer after common superplasticizer and superplasticizer.…
Because the steric hindrance of the extended polymer side chain effectively hinders the secondary agglomeration between cement particles, so the product has high dispersion performance and can maintain this performance for a long time to realize the…
Common superplasticizers include lignosulfonates and their derivatives, advanced polyols and polyol complexes, hydroxy carboxylic acids and their salts, polyvinyl ethers and their derivatives, etc.…
Polycarboxylate superplasticizer is often used in concrete, which can reduce the water consumption of concrete while maintaining the same fluidity, thus improving the strength and durability of concrete.…
Polycarboxylate superplasticizer has more advantages than traditional naphthalene and aliphatic superplasticizer in mixing high strength grade concrete, but its advantages of high water reduction cannot be brought into full play when the strength is…
Natural river sand has been exhausted after decades of large-scale mining, concrete production enterprises began to use machine-made sand as fine aggregate on a large scale.…
In order to improve the early strength of concrete, some manufacturers will add triethanolamine, calcium chloride and industrial salt to the superplasticizer, especially in winter or prefabricated component factories and cement products factories tha…
If the compatibility of polycarboxylate superplasticizer and cement is not good, the concrete mixture is prone to some problems, such as segregation, bleeding, greater slump loss, shorter setting time and so on, so that the concrete mixture can not b…
The wide application of mineral admixtures mainly derived from industrial solid wastes diversifies the composition of cementitious materials, which is one of the main characteristics of modern concrete.…
Adding polycarboxylate superplasticizer can make the compressive strength of precast concrete reach 40MPa grade at 8h to 18h.…
The impermeability of concrete is related to its porosity and pore structure.…
Dodecyl Dimethyl Benzyl chloride is primarily used in acrylic mixtures, fabric softeners, and antistatic agents. About Dodecyl dimethyl benzyl ammonium chloride: Dodecyl benzyl ammonium chloride has the properties of rich and fine foams, low degre…
Welding electrode tungsten copper alloy has heat resistance, arc ablation resistance, high certain gravity and high electrical and thermal conductivity. It is very easy to make and suitable for welding electrodes, with great high-temperature stamina…
The application of fourth-generation and fifth-generation rapid test kits is currently high. The adoption and innovation of digital HIV self-testing tools have increased in recent times, with website-based innovation becoming highly popular.…
