In the age of the building industry, in addition to the most important cement building products, there is also a product plays an important role, that is the concrete additives, a variety of reasonable use of this product can greatly reduce costs on the cost, that what are the additives, how we can reasonable use, today will give you do a simple introduction.
Polycarboxylic acid water reducing agent (PCE) is one of the most important concrete water reducing agents because of its excellent performance. Compared with other products such as polycondensates, they fluidize cement even at lower water cement levels, require relatively lower doses and have longer slump retention.
It is synthesized from unsaturated monomer of carboxylic acid and large monomer of long chain alkane. PCE can be generally divided into polyesters and polyethers according to the connecting form of its main and side chains. The structure of polyester -PCE is characterized by the ester bonds of its main and side chains.
The key of the synthesis technique is the esterification or transesterification of the macromolecule monomer with methoxy polyethylene glycol and acrylate. Polyether reactions are obtained by radical polymerization using the direct polymerization of large and other small monomers of alkenyl polyethylene glycol ethers (carboxylic acids and sulfonic acids) in an aqueous solution.
There are many types of water reducing agent, according to incomplete statistics, there are 15 kinds of as much as possible. Today, we will give you the most common types of water reducing agent.
In the process of using additives, the solid content of additives is different, so in the process of using, in order to make it evenly mixed, we will dilute with water first. When the dilution reaches a certain proportion, we will carry out the relevant mixing, which can play the role of concrete on the ground.
The above is the latest relevant knowledge about concrete and relevant use skills, there is any you want to know, you can contact us as soon as possible, will try to answer for you.
