1. Usage and characteristics:
This agent has the functions of early strength, water reduction and enhancement, and is a natural maintenance admixture. This agent is generally used in concrete used in brick-concrete structures. Concrete mixed with this agent can reach more than 70% of the design mark after 5 days of molding at normal temperature. The strength of ring beams, structural columns, balconies, awnings and other components cast by concrete mixed with this agent increases rapidly, and the strength will still increase accordingly in the later period. The use of this agent can not only shorten the construction period, but also ensure the quality of the project.
2. Scope of application:
This agent is suitable for ordinary concrete and concrete with early strength or anti-freeze requirements that are constructed in normal temperature, low temperature and negative temperature (the lowest temperature is not less than -5℃) environments. Reinforced concrete and prestressed concrete engineering.
3. Implementation standard: GB8076-1997
4. Dosage and usage:
1. Dosage is 3%-5% of cement quality.
2. The mixing and vibrating of concrete with early-strength water-reducing agent can be the same as that of concrete without additives. When the powder is added to the mixer, it should be dry-mixed with cement and aggregate before adding water. The mixing time should not be less. in 3 minutes.
3. When using natural curing, it should be covered with plastic film. When it is low temperature, it should be covered with insulation material.
5. Storage and packaging:
1. Woven bags lined with plastic bags weighing 50kg each.
2. This agent is in powder form. Be careful not to damage it when handling. It should be protected from moisture when storing. If there is moisture and agglomeration, it should be crushed and passed through a 0.63mm sieve before use.
3. Storage period: two years . </p
