Water-reducing agents are an important component of grout. They are admixtures that can significantly reduce the water content of grout while maintaining its fluidity. The amount of water-reducing agent can change the fluidity of grout, improve workability (while maintaining the same amount of cement and water-cement ratio); due to the reduction of the water-cement ratio, […]
Specific limitations Over the past few decades, concrete has become the main material in construction, especially in densely populated urban environments. Thanks to its low cost, ease of use and scalability, concrete has gradually replaced bricks, stone and wood. But it is not without problems. Sustainability First and foremost, it is far from a sustainable […]
1.Raw materials The fineness modulus and silt content of sand must meet the requirements, and the water content should not exceed 6% during use. The sampling of sand must not take the surface layer and the oversize particles of the upper gravel, etc. must meet the requirements, especially the silt content (stone powder content). If […]
Leading coatings manufacturers are seeing more interest in DIY projects and home renovations as opposed to new construction. The architectural paint and coatings market is the largest segment in the coatings industry, with estimates from MarketsandMarkets placing it at approximately $85 billion in 2023. Other estimates are fairly similar in terms of revenue. It is a market […]
The primer improves the adhesion of the self-leveling compound The self-leveling primer is part of the ground base treatment and is an essential item in the self-leveling construction. It is very important and directly affects the adhesion between the self-leveling compound and the base ground. The amount of primer used is actually relatively small, and […]
1. Cellulose ether has a certain retarding effect on mortar. As the dosage of cellulose ether increases, the setting time of the mortar is extended. The retarding effect of cellulose ether on cement slurry mainly depends on the degree of substitution of the alkyl group. The smaller the degree of substitution of the alkyl group […]
According to a new study published by Knowledge Sourcing Intelligence, the tartaric acid market is projected to grow at a CAGR of 5.34% between 2025 and 2030 to reach US$419.490 billion in 2030. Tartaric acid plays a very significant role in different sectors as a naturally occurring organic acid. It is found predominantly in grapes and some […]
In the field of construction engineering, concrete is a widely used building material, and its performance is directly related to the safety and durability of the entire building structure. However, in cold regions or during winter construction, concrete frost damage often occurs, causing many problems in construction. A deeper understanding of the causes of concrete […]
CPCA’s Canadian Coatings Conference will be held May 21-23, 2025 at the Marriott Halifax Harbour Front. The Canadian Coatings Conference is the leading source for addressing regulatory developments impacting the Coatings, Adhesives, Sealants, and Elastomers (CASE) industry in Canada. Hosted by the Canadian Paint and Coatings Association (CPCA) with a strong mandate to advocate for fair regulations that […]
As the understanding of foam stability factors continues to grow, so does the understanding of the defoaming mechanism. Foam stability factors are diverse, and so are the defoaming mechanisms. Reducing local surface tensionSome people have studied the defoaming process of polysiloxane in oily systems: the silicone oil defoamer droplets reach the bubble film, causing the […]
