Specification of Polypropylene Micro Fiber for Concrete Lining

제품개요

Polypropylene micro fiber is an artificial reinforcement made use of in concrete cellular linings for passages and pipes. It improves the longevity and performance of concrete without replacing conventional steel reinforcement. The fibers are equally dispersed throughout the mix to regulate breaking and boost durability.

트릭 포함

– 분할 제어 : The fibers decrease plastic shrinkage fractures throughout early healing.
– Impact Resistance : Concrete becomes extra immune to unexpected loads or impacts.
– 균일한 분산 : Fibers mix conveniently and spread uniformly in common concrete batches.
– 부식 방지 : 강철과 달리, polypropylene does not corrosion or break down gradually.
– 작업성 : Does not conflict with pumping, 퍼팅, or completing of concrete.

기술 사양

– 제품 : 100% 버진 폴리프로필렌
– Fiber Size : 6 mm 에 19 mm (일반적으로 12 mm for passage cellular lining).
– 지름 : 18세쯤– 32 미크론.
– 인장 체력 : 최저한의 450 MPa.
– 해동 인자 : 약 165 ℃.
– 선량률 : Typically 0.6– 1.0 콘크리트 입방미터당 kg.

적용기준

Include fibers throughout the first blending phase in addition to aggregates and water. 최소 3개 이상 혼합– 5 완전한 확산을 보장하는 데 몇 분. 특별한 장비가 필요하지 않습니다. The product functions well with various other admixtures like water reducers or air-entraining agents. Always follow regional concrete codes and job specs when creating the mix.

보관 공간 및 취급

건조한 곳에 보관하세요., 직사광선으로부터 멀리 떨어진 보호 구역. Maintain bags sealed up until use to avoid dampness absorption. Take care of with basic building and construction safety methods– no hazardous fumes or skin irritants are present.

Applications of Concrete Admixture Polypropylene Micro Fiber for Concrete Lining of Tunnels and Pipes

Applications of Polypropylene Micro Fiber in Passage and Pipe Concrete Linings

Why Make Use Of Polypropylene Micro Fiber?

Polypropylene micro fiber is included in concrete used in passages and pipelines. It aids control fracturing from the very beginning. 콘크리트가 마르면, 그것은 감소한다. This shrinkage commonly creates tiny fractures These cracks can grow in time and compromise the framework. The tiny fibers spread out uniformly through the mix. They hold the concrete with each other at a microscopic level. This lowers early-age fracturing and enhances lasting resilience.

Performance in Tunnels

Passage linings encounter continuous stress from ground motion, 수압, 그리고 온도 변화. Plain concrete might crack under these problems. Including polypropylene micro fiber makes the lining much more resistant to such stress and anxieties. The fibers imitate inner support. They do not replace steel rebar however work along with it. 함께, they help maintain architectural honesty also when minor shifts occur. Workers additionally discover the concrete simpler to put and finish because the fibers decrease surface area bleeding and segregation.

Advantages for Pipe Construction

Concrete pipelines must manage inner liquid stress and external dirt tons. Fractures in pipelines cause leaks and deterioration. Polypropylene mini fiber lessens this risk. It increases the concrete’s ability to withstand impact and abrasion throughout handling and installation. The fibers also lower leaks in the structure. This suggests water and dangerous chemicals find it tougher to go through the concrete. 이 때문에, the service life of the pipe boosts without additional maintenance prices.

트릭의 장점:
– Lowers plastic and drying out shrinkage splits.
– Enhances toughness and effect resistance
– Improves harmony of the concrete mix
– Decreases permeability for far better waterproofing
– 사용하기 쉬운– simply add during blending

Service providers and designers select polypropylene micro fiber since it provides dependable efficiency with marginal modifications to conventional methods. It works well in both precast and cast-in-place applications for passages and pipelines.

5 FAQs of Concrete Admixture Polypropylene Micro Fiber for Concrete Lining of Tunnels and Pipes

자주 묻는 질문: Polypropylene Micro Fiber for Concrete Lining

What is polypropylene micro fiber used for in tunnel and pipe lining?

Polypropylene micro fiber is added to concrete mixes for tunnels and pipes. It helps control early-age cracking caused by shrinkage. The fibers spread evenly through the mix and hold the concrete together as it dries. This makes the lining more durable and less likely to crack.

이 섬유가 콘크리트 성능을 어떻게 향상시키는가??

The tiny fibers create a network inside the concrete. This network reduces plastic shrinkage cracks that form while the concrete is still wet. It also boosts impact resistance and helps the lining stay intact under stress. 결과는 더 빡세다, more reliable structure.

Is polypropylene micro fiber easy to mix into concrete?

예. The fibers disperse well during normal mixing. 특별한 장비가 필요하지 않습니다. Just add them at the start of the batching process. They blend smoothly with cement, 모래, and water without clumping.

이 섬유가 강철 보강재를 대체합니까??

아니요. Polypropylene micro fiber is not a replacement for steel rebar or mesh. 2차 강화 역할을 합니다.. Its main job is to manage small cracks during curing. Structural strength still comes from traditional steel reinforcement.

Is the fiber safe for use in underground structures?

예. 폴리프로필렌은 화학적으로 불활성입니다.. It does not corrode, 녹, or react with other materials in concrete. This makes it ideal for tunnels, sewers, and buried pipes where long-term stability matters. 섬유는 구조물의 수명 동안 효과적인 상태를 유지합니다..
