Detail
This product has all the characteristics and performance indicators of expansion agents, with high and stable expansion performance. The concrete mixture used for preparation has low slump loss and is a technically strong and high-performance product. This product can be widely used in compensating shrinkage concrete structure self waterproofing technology, seamless construction technology, large volume concrete crack control technology, rigid waterproof roof construction technology, and injection pile construction technology to improve pump pile bearing capacity. It is a new product that conforms to the development direction of expansion agents.
Scope of Application
Concrete engineering and cement products that require anti-seepage, crack resistance, and filling can be used. Such as underground buildings, subways, underground parking lots, tunnels, civil air defense projects, etc. Reservoirs, swimming pools, water towers, grain warehouses, etc., rigid roof waterproofing, highway pavement, bridge concrete surface layer, or high-strength, high anti-seepage vertical shafts for buildings, and concrete filling for dam return grooves.
Technical performance
Appearance: Grey brown powder;
Fineness:<10% (using 0.08mm sieve residue);
Moisture content:<3%;
Compressive strength: 7d>30Mpa, 28d>50Mpa;
Flexural strength: 7d>6.5Mpa, 28d>10Mpa;
Impermeability grade:>P30
Instructions for use
Suggested dosage: 8-12% of the cementitious material. This agent can be directly added together with concrete aggregates, but the mixing time should be extended by 1 minute, or when used as commercial concrete, the mixing time does not need to be extended.
Precautions
When using this product, it is essential to ensure accurate measurement.
When the reinforcement ratio is 0.2-1.0%, its limited expansion rate can reach 2-4 × 10-4, while the cement shrinkage rate is 2-3 × 10-4. When there is anti-seepage engineering construction, the use of this agent must not be arbitrarily reduced to avoid the anti-seepage level of the project not meeting the design requirements.
Be cautious of moisture. This agent may lose its expected expansion performance due to moisture, thus failing to achieve its anti-seepage and crack resistance effects;
This agent can be used together with other additives, but it should be determined through testing.
Packaging and storage
This product is non-toxic, non explosive, and non-volatile. It should be stored in a well ventilated and dry place, and should not be affected by moisture. It should be transported as general cargo. The storage time of the product is one year, but if it exceeds six months, it should undergo physical performance testing again.
