SINTA™ F Fibres, SINTA™ M Fibres

Control early age plastic shrinkage with synthetic microfibres

Where fibres are concerned, the rate at and consistency at which they're delivered into concrete is as important as the makeup of the fibres themselves. SINTA™ F Fibres can be specified wherever contractors need to reduce early age plastic shrinkage cracking, lower permeability, increase durability and more. The SINTA™ FDS is an innovative fluid dispensing system delivering the microfibres efficiently at the batching plant.

SINTA™ M3106
Description

SINTATM M3106 is a micro-synthetic polypropylene fiber that can be used in many concrete applications. It helps to prevent the propagation of cracks during plastic shrinkage, and crack reduction during plastic settlement. SINTA M3106 is produced on a state-of-the-art production line which is specifically designed to yield an ultra-thin concrete fiber. Engineered specifically for use in concrete, it is 100% alkali-resistant, and completely non-corrosive. It provides secondary reinforcement and protects concrete from stresses which cause cracking while the concrete is most vulnerable — during the first 24 hours after placement. It therefore enables the concrete to be more durable over the entire service life. It can be directly mixed into concrete, and this helps reduce both time and effort in transporting and installing traditional steel mesh for shrinkage/ temperature crack control.
SINTA M3106 is available in 6mm lengths, 30-32 microns diameter.

Key Benefits

SINTA M3106 uniformly distributes multi-dimensionally throughout the concrete mixture. The extremely high number of fibers in the fresh concrete matrix provides a high degree of secondary reinforcement. This reinforcement reduces the formation of all types of early cracking, protecting the concrete when its tensile strength is lowest. This cracking caused by plastic shrinkage, settlement, and other internal stresses would otherwise permanently weaken the resulting concrete. The concrete permeability is decreased, while surface characteristics, impact, and toughness properties are improved. Instead of installing steel mesh on jobsite, applying SINTA M3106 reduces both time and direct labour expenses significantly; potential hazards and risks related to handling steel mesh are eliminated. SINTA M3106 does not corrode, and this increases concrete service life and also minimizes any maintenance costs; at the same time, SINTA M3106 can be stored for a long-term without risk of becoming not useable due to corrosion.

Application Type
Overview

Where to use SINTA™ F Fibres?

SINTA™ F Fibres may be used in any application where designers, contractors, or producers want decreased cracking due to plastic settlement. These microfibres help to lower permeability. In addition, SINTA™ F, SINTA™ M or SINTA™ FDS microfibres increase concrete cohesiveness, which enables contractors to place concrete on steep inclines and in slipform without tremendous difficulty. Applications where synthetic microfibres can be used include slabs on grade, overlays, sloped walls, pools, shotcrete, stucco, tunnels, precast and prestressed products.

What are the advantages of SINTA™ F Fibres?

Use of SINTA™ F Fibres reinforces a fresh concrete mixture while its tensile strength is weakest by mechanically locking into the concrete matrix. Plastic shrinkage cracking and permeability are both reduced. At the same time, SINTA™ F Fibres increase impact, abrasion, shatter and fire-spalling resistance of the concrete. Taken together, these improvements produce higher-quality and higher-durability concrete over the lifetime of a structure.

SINTA™ F Fibres  are compatible with all other our admixtures. Producers can achieve amazing strength, flexibility and finishability by using SINTA™ F Fibres products in combination with superplasticisers such as ADVA®.
