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 […]
Cellulose ether is a non-ionic, semi-synthetic polymer that is water-soluble and solvent-soluble. It has different effects in different industries. For example, in chemical building materials, it has the following composite effects:① water retention agent ② thickener ③ leveling ④ film-forming ⑤ binderIn the polyvinyl chloride industry, it is an emulsifier and dispersant; in the pharmaceutical […]
When the silver bell tinkles and the snowflakes fall, the scent of Christmas quietly fills every corner of VITCHEM. During this warm and joyous holiday season, we pause together from our busy lives, look back on our hard work in the past, look forward to the infinite possibilities of the future, and celebrate our Christmas […]
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 […]
The world’s first,S$200 million ready-mixed concrete ecosystem has officially opened at Jurong Port. Its productivity will double, and it will reduce carbon emissions by more than 25,000 tons per year, equivalent to the annual electricity consumption of about 12,750 four-room HDB flats. Ready-mixed concrete is one of the most commonly used materials in construction. It is […]
