Test steps for water reducing rate of water reducing agent in concrete
The concrete ratio for testing water reduction rate is not the C30 concrete ratio. Measuring water reduction rate has nothing to do with concrete strength. If you have read the specificationMix propor…
If I use water reducing agent, will it affect the effect of the concrete?
(1) Improve the workability of concrete and reduce single water consumption. The strength of concrete is related to the water-cement ratio. Reducing the water-cement ratio can increase the strength of…
How to calculate how much water reducing agent is used for one cubic meter of concrete?
What is the main component of the water-reducing agent? Lignin sulfur calcium (agent) is generally 0.2%~0.5%. Naphthalene-based water-reducing agent is generally 0.5%~0.75 % Water-soluble water-solubl…
Why is water reducing agent added to concrete during construction?
A key parameter of the concrete mix ratio is the water/cement ratio, that is, the ratio of water/cementitious material (cement + active mineral mixture). The higher the water/glue ratio, the better th…
What should I do if I put too much water reducing agent in the concrete?
Adding too much water-reducing agent will cause the concrete to separate and bleed, causing bottom-grabbing and no cohesion. It will cause trouble for transportation. In addition, because there are ma…
Four functions of adding water reducing agent to concrete
1. Dispersion effect. The water-reducing agent molecules can be directionally adsorbed on the surface of cement particles, so that the surfaces of the cement particles carry the same charge (usually n…
Three situations will affect the performance of early strength water reducing agent
Early-strength superplasticizer has relatively good performance and is widely used in the construction industry. However, there is a problem that cannot be ignored. In high-temperature environments, t…
The working principle of early strength water reducing agent Jiangsu water reducing agent manufacturer Anhui early strength water reducing agent price
Technical Principle The main chain of early-strength high-performance water-reducing agent molecules is firmly adsorbed on the cement particles On the surface, it can effectively hinder the hydration …
15 sentences summarizing all the functions of early strength water reducing agent
1 Improve the workability of concrete or mortar mixtures during construction; 2 Improve the strength and other physical and mechanical properties of concrete or mortar; 3 Save cement or replace it Spe…
How to know the usage density of early strength water reducing agent
The side chains of early-strength superplasticizers have an important impact on the dispersion and dispersion retention of cement particles. The smaller the degree of polymerization of the side chains…
