Redispersible polymer powderRedispersible polymer powder is a spray-dried dispersion that can form a stable dispersion when added to water. It has the same properties as the original emulsion and is a commonly used dry powder mortar additive in putty. 1. The role of the flexibility of the polymer powder Redispersible polymer powder is needed in […]
AkzoNobel celebrates a long and successful history in China. Marine and protective coatings brand International, part of AkzoNobel, celebrated its 35th year anniversary in China during an event in Shanghai in October 2024. First registered and founded in 1989 in partnership with Shanghai Huayi Fine Chemicals and China State Shipbuilding Equipment & Materials Corporation Ltd, International Paint of Shanghai Co., […]
Chemical stability is a necessary condition for defoamers, so defoamers in foaming systems generally do not fail due to chemical reactions. Most of the reasons for their failure are caused by changes in the dispersion state. Only by eliminating this cause can the effectiveness of the defoamer be fully exerted. 1. The defoamer particles have […]
Durability 1. Defoamers are compatible with surfactants. For example, defoamers are more effective at the beginning, but their effectiveness will be greatly reduced after a period of time. 2. The main agent of the defoamer can be absorbed by the resin particles. The applicable pH range of defoamers: the use of defoamers in an environment […]
This year’s theme is “Coatings and Technologies for a Resilient Future.” The American Coatings Association will host its 2025 CoatingsTech Conference April 28-30, 2025 at the Omni William Penn in Pittsburgh, Pa. This biennial conference features multi-track sessions, industry awards, and presentation opportunities for new developments and research for both industry professionals and students centered […]
The superiority and stability of the performance of plastering mortar applied mechanically is a key factor in development, and cellulose ether, as a core additive for plastering mortar, plays an irreplaceable role. Cellulose ether has the characteristics of high water retention and good wrapping, and is particularly suitable for the mechanised application of plastering mortar. […]
Scientists at Nanyang Technological University, Singapore (NTU Singapore) have pioneered a 3D concrete printing method that captures and stores carbon dioxide, marking a major step toward reducing the construction industry’s environmental footprint. The innovative technique offers a promising solution to mitigate cement’s massive carbon emissions. The process works by integrating CO₂ and steam—byproducts of industrial […]
High-performance concrete is concrete with excellent workability, mechanical properties and durability that is made to meet the specific requirements of construction projects using high-quality conventional raw materials and an optimised mix design, through green production methods and strict construction measures. As an important green building material, the promotion and application of high-performance concrete in infrastructure […]
A private-public partnership has paved a section of Minnesota road with an experimental low-carbon concrete mixture that resulted in greater strength and lesser cement use, saving money and carbon. Concrete and its most important ingredient, cement, is one of the most carbon-intensive industries on Earth because it’s used so often in construction. It has virtually […]
Concrete cracks are a common and troublesome problem in construction. They not only affect the appearance of buildings, but may also lead to functional problems such as leakage, which in turn threatens the safety and durability of the building structure. 1. Material factors: ◆Cement: The heat of hydration of cement is one of the important […]
