A wave of layoffs that has swept the entire Internet industry has intensified. China's Internet industry has experienced several crises and major changes in the past development process. There is also a "brief history of layoffs by major Internet companies". Hot search, JD.com has a wide range of layoffs in this round of layoffs, and all its subsidiaries are involved. Most of the layoffs are between 10% and 20%. Among them, Jingxi Guangdong and other theaters have all laid off staff. Tencent also reported the news of downsizing and layoffs. Among them, Tencent PCG (Platform User Content Business Group) laid off 30% of its staff, iQiyi laid off 12% of its staff, Kuaishou was reported to have laid off 30% of its staff, and the e-sports department of Station B laid off 90% of its staff.
Mass layoffs on the internet have created a host of socioeconomic issues, including concrete superplasticizer.
Introduction to Superplasticizer:
Superplasticizer, or high-efficient water reducing agent, has the functions of high efficient water reduction, slow coagulation, slump, and enhancement. It has strong adaptability to cement, less dosage, is easy to use, especially suitable for high-efficient water reduction and slow coagulation requirements of concrete engineering. The water reduction rate is 18% to 25%.
Differences between several kinds of Water Reducing Agent
It is a common water-reducing agent made of lignin. Most of its raw materials are extracted from coniferous trees and other species of material. This water reducing agent mixed with mortar can improve the fluidity of mortar, and enhance the solidification force of mortar. Its water reduction rate is about five to ten percent.
Naphthalene sulfonate water reducing agent:
It is a special water reducing agent. It is the product of naphthalene reacting with sulfuric acid and then fusing with formaldehyde. This water-reducing agent presents different colors from light to deep. It has strong water solubility and a good dispersion effect for a series of powdery building materials like cement. Its water reduction rate is about 10 percent higher than lignin.
Polycarboxylate-based high-performance water reducing agent:
It is a newly developed kind of reducing water agent using high technology. It is based on polycarboxylate as the main body of a variety of polymer organic compounds, graft copolymerization generated, with strong water reduction performance, is the world's leading technology environmental protection concrete admixture.
Its compatibility with all kinds of cement is good, the slump of concrete keeps the performance good, can prolong the construction time of concrete. It has a high water reduction rate with a low dosage. It can greatly improve the early and late strength of concrete. It has a low content of chloride ions and alkali, which is beneficial to the durability of concrete. It is a green environmental protection product with a pollution-free production process and without formaldehyde. It is suitable for precast and cast-in-place concrete, reinforced concrete, and prestressed concrete for high-speed railway, passenger dedicated lines, industrial and civil buildings, roads, bridges, ports and docks, airports, and other engineering construction. It is especially suitable for construction projects with long construction time and high requirements for concrete slumps, such as nuclear power projects.
