Fiber anti-crack expansion agent

product description

This product has the characteristics and performance indicators of all expansion agents, and its expansion performance is high and stable. The concrete mixture used to prepare the concrete mixture has a small slump loss and is a product with strong technical skills and good performance. This product can be widely used in self-waterproofing technology to compensate for shrinkage of concrete structures, seamless construction technology, large-volume concrete crack control technology, rigid waterproof roof construction technology and cast-in-place pile construction technology to improve the bearing capacity of pump piles, etc. It is in line with the development direction of expansion agents. new products.

Scope of application

It can be used for concrete projects and cement products that require anti-seepage, crack resistance, and filling. Such as underground buildings, subways, underground parking lots, tunnels, civil air defense projects, etc. Pools, swimming pools, water towers, granaries, etc., rigid roof waterproofing and highway pavement, bridge concrete surface layer or building high-strength, high-impermeability shafts, dam return trough filling concrete.

Technical performance

Appearance: grayish brown powder;

Fineness: <10%（Use 0.08 mm sieve residue);

Moisture content: <3%；   

Compressive strength: 7 d>30Mpa，28d>50Mpa；   

Flexural strength: 7 d>6.5Mpa，28d>10Mpa；   

Impermeability label: >P30

Instructions

Recommended dosage: 8-12% of cementitious material. This agent can be put in directly together with the concrete aggregate, but the mixing time should be extended by 1 minute, or when used as commercial concrete, there is no need to extend the mixing time.

Precautions

When using this product, be sure to measure accurately.

When the reinforcement ratio is 0.2--1.0%, its limited expansion rate can reach 2--4 ×10-4，，The dry shrinkage rate of cement is 2-3 ×10-4，，When constructing anti-seepage projects, this agent must not be used at random to avoid the anti-seepage level of the project failing to meet the design requirements.

Beware of moisture. This agent may lose all its expansion properties due to moisture, thus failing to achieve anti-seepage and anti-cracking effects;

This agent can be used together with other admixtures, but it should be determined through testing.

Packaging and storage

This product is non-toxic, harmless, non-flammable and non-volatile. The product is stored in a ventilated and dry place. It is strictly prohibited to get damp. It is transported as general cargo. The product storage time is one year, but if it exceeds six months, the physical properties should be re-inspected.
