Polycarboxylate water reducing agent (PCA) is a polymer surfactant prepared by copolymerization of a carboxyl group-containing unsaturated monomer and an unsaturated monomer containing other functional groups. It is a new generation of high-efficiency reduction after naphthalene-based water reducing agent.

The terms cement, concrete, and mortar can be confusing to beginning builders, but the basic difference is that cement is a fine binding powder (which is never used alone), mortar is composed of cement and sand, and concrete is composed of cement, sand, and gravel. In addition to the differences in

Concrete segregation refers to that the amount of the pumping agent exceeds the saturation point of the cementing material, and the resistance between the particles of the cementing material decreases and the displacement accelerates.

On the morning of April 20, 2018, the 7th "China concrete admixture products and equipment exhibition" opened in Xiamen. The fair is from April 20 to 22 for 3 days, a total of 63 companies promote themselves in various forms of enterprises and products

Polycarboxylate Superplasticizer is a new generation superplasticizer based on modified polycarboxylate particularly recommended for ready mixed concrete and civil engineering construction. Its particular configuration allows its delayed adsorption onto the cement particles and disperses them effici

In the past five years, the continuous improvement of the comprehensive performance requirements of the roof has promoted the innovative development of roof design. The roofing association, as always, has worked with its members to seek innovative solutions to the application of concrete tiles

Domestic most of the original road pavement structure of cement concrete panel, this kind of structure joints and cracks easily, eventually lead to diseases such as fault sets, escapes, pavement damage, and influence the comfort of driving.

What are Admixtures ?They are natural or manufactured chemicals which are added to the concrete before or during mixing.Commonly used are Air-entraining agents, Water reducers, Water-reducing retarders and Accelerators.Why are they Used ?They are used to give special properties to fresh or hardened

The agency has investigated the recent trend of ethylene oxide in nine production companies and 11 downstream users. Three of them think the price of ethylene oxide will fall this week, accounting for about 15%.There are 12 users who believe that the price of ethylene oxide will be stable this week,

Admixtures are those ingredients in concrete other than portland cement, water, and aggregates that are added to the mixture immediately before or during mixing . Admixtures can be classified by function as follows: 1. Air-entraining admixtures 2. Water-reducing admixtures 3. Plasticizers 4. Acceler
