The optimal dosage of early-strength water-reducing agent, the results obtained after hundreds of trials
Main properties and parameters of early-strength superplasticizer: 1. The dosage is 0.5% of the weight of cement ~ 1%, the water reduction rate can reach 12% ~ 25%; 2. The early strength increases qui…
Is high-efficiency concrete water-reducing agent harmful to the human body?
Hazardous chemicals refer to highly toxic chemicals and other chemicals that are toxic, corrosive, explosive, flammable, and combustion-supporting, and are harmful to the human body, facilities, and t…
Is it possible to reduce the amount of cement and water by adding a water-reducing agent to concrete?
Everyone knows that water-reducing agents have the effect of reducing water, so for example, the mix ratio I calculated is: cement 300: sand: 160: gravel: 1000: water 120: Water reducing agent: %1.5. …
Does adding water-reducing agent to concrete have this effect? Why don’t I feel it?
1. Without changing the ratio of various raw materials, adding high-efficiency concrete water-reducing agent will not change the strength of concrete, and at the same time, it can greatly improve the …
Synthesis process and environmental performance of early-strength water-reducing agent
Water reducing agent is one of the main raw materials for the production of high-performance concrete. There are also some water reducing agents on the domestic market at present. However, when it com…
By chance, I obtained a rare early-strength water-reducing agent compound method.
Commonly used compound materials include sodium gluconate, dextrin, air-entraining agents, defoaming agents, sodium nitrate, inorganic salts, alcoholamine enhancers, etc. The compounding methods are: …
The seemingly simple mechanism of action of concrete water-reducing agent
Polycarboxylate performance model water-reducing agent is a new type of water-reducing agent that has many outstanding advantages, but its functional principle is not completely clear at this stage. T…
