Revealed: Why is concrete admixture added to concrete?
In order to effectively improve the workability, strength, and durability of concrete and reduce the deformation of concrete, sometimes in order to make the concrete condense quickly or delay the aggl…
Three-point test data proves the effect of water-reducing admixture on concrete strength
What are the effects of water-reducing admixtures on the strength of concrete? They all need to be obtained through practice. After a large number of repeated practical studies by relevant technical p…
Concrete admixture gb23439 is actually a concrete expansion agent
Customers often ask what concrete admixture gb23439 is. In fact, it is a type of concrete admixture, an expansion agent. The editor below will give you a brief introduction to the performance and func…
What should I do if I add too much admixture coagulant to the concrete? Do I need to add cement?
Because admixtures can improve and adjust the properties of concrete, admixtures are used more and more widely in engineering. However, improper use of admixtures will not only fail to improve and adj…
The first test of concrete admixture water reduction rate showed good results
The test method for the water reduction rate of admixtures is carried out according to the GB8076-2008 “Concrete Admixtures” standard. Water consumption: The slump of high-performance wate…
The amount of concrete admixture cannot be much more than the mass of cement
The dosage of concrete admixtures is generally not more than 5% of the cement mass. Concrete admixtures refer to substances added to improve and adjust the properties of concrete. The application of c…
How to determine the amount of concrete admixture
Calculation of concrete admixture dosage 1. Construction preparation During the concrete mixing process, materials that can improve and adjust the properties of concrete as required are called concret…
Two classifications of concrete admixtures and explanations of 16 admixture terms
According to (GB8075-87) classification, concrete admixtures can be divided into four categories according to their main functions: Admixtures that improve the rheological properties of concrete mixtu…
Solution to concrete admixture polycarboxylic acid secret water
1. The preparation ratio is wrong. 2. Issues with cement and admixtures. Problems with polycarboxylate water-reducing agents 1. Insufficient slump retention in high-temperature environments; 2. Strong…
It is enough to add retarder admixture directly to concrete. Do you have any ideas?
(1) Pay attention to the mutual adaptation with the cementitious material system. For different cementitious material systems, they can show different condensation and hardening properties, and they a…
