Use
一、“SISIYUAN” Fiber used in concrete
1、Proposes to add the amount of
Per cubic meter of concrete proposed to add 12-19mm fiber 0.6-1.8kg, the original concrete mix proportion unchanged. (For reference)
2, using the method
According to the project asked to select a different dosage, add the amount given in front of, within the higher the dosage the better crack resistance, "SISIYUAN" fiber reinforcement in the concrete to play the role of physics, fiber itself is inert material, not with other concrete ingredients and additives react with fiber admixture does not change the original concrete mix, the performance of various aggregate indicators of no special requirements.
① cast materials and methods in order
When used fiber and sand and stone aggregate is also added, add water to the wet mix can be
The best aggregate in Canada, while the fibers added to the middle of sand and gravel materials, the effect will be better.
② fiber reinforced concrete mix
Mixing time than concrete without fibers slightly longer mixing time of 30-60 seconds, to ensure that fiber can be evenly mixed in the concrete. (High dispersion products in the commodity would not be necessary to extend the concrete mixing time)
3, Slump Adjustment
Thickening due to the role of fiber makes the fiber's entry would increase the viscosity of concrete mixing materials to slump slightly lower. Each project requires a different degree of collapse, so the project prior to use experimentally adjust slump, if the slump does not meet the construction requirements, increase the amount of water should not be used to increase the slump, but should be an appropriate use of plasticizers or water-reducing agent to increase the slump to meet construction requirements.
4, the intensity of test
Adding fiber does not affect the strength of concrete, but it should be before use in each project have been identified according to the provisions of the concrete mix for fiber concrete strength test.
5, knock off pressure surface
Concrete can be a model to conduct a post-pressure side, to be completed before the end of the second initial setting of concrete surface pressure in the pressure side should make full use of steel or iron trowel, smooth enough wood fiber will be triggered.
6, surface type and maintenance
Incorporation "SISIYUAN" fiber concrete in the molding no special requirements, but should ensure the concrete to fully tap.
Incorporation "SISIYUAN" fiber concrete curing no special requirements, according to the normal concrete curing can not be due to incorporation of "SISIYUAN" fiber relax early on concrete conservation.
7, Indicating
"SISIYUAN" fiber only as a secondary ribs of concrete, the main role is to inhibit the production of concrete cracks and improve the impermeability of concrete substrate ability to extend the service life of concrete, rather than major structural reinforcement force.
Thus, "SISIYUAN" doped fiber can not change the original design of the reinforcement ratio.
2, "SISIYUAN" fiber used in mortar
Mortar as construction materials, often occur during the actual construction process of a number of drawbacks: brittleness, dry shrink large, low tensile strength, deformation capacity of low and poor impact resistance, so that cracks in mortar products easily, thereby reducing the durability of buildings sex.
Our research institutes jointly developed with the mortar of a new generation of dedicated organic fiber ---- modified polypropylene (PP) fiber, with a special production process and surface treatment, cross-section was clover (Y) type, excellent mechanical properties , mixing mortar, showing three-dimensional chaos to the uniform distribution, high dispersion, and strong bond strength of mortar, can prevent, reduce and delay due to creep, plastic shrinkage, dehydration shrinkage, chemical shrinkage, temperature and load caused by a variety of factors such as micro-cracks, and thus significantly improve the cracking mortar products, impermeability, so that mortar integrity, flexibility, continuity and durability can be improved.
The use of "SISIYUAN" brand polypropylene fibers, no additional special equipment, without changing the composition of mortar, construction, easy to operate, costs little and will not cause pollution to the environment, which has been widely used in the mortar. 
1, Proposes to add the amount of
Per cubic meter of mortar proposes to add 6-10mm fiber 0.9-1.2kg. Amount based on the engineering requirements of admixture choose a different dosage, add the amount given in front of, within the higher the dosage the better crack resistance.
2, cast materials and methods in order
① Dry mix
Use, add some sand to the mixer, cement, add "SISIYUAN" fiber to ensure uniform fiber falls cement, sand in, then add the remaining cement and sand, mixing time to fibers uniformly dispersed in the mortar shall prevail.
② wet-mix
Use, add some sand to the mixer, cement, add "SISIYUAN" fiber to ensure uniform fiber falls cement, sand in, then add the remaining cement, sand and water, stirring time to fibers uniformly dispersed in the mortar shall prevail.
3, mixing time,
The best use of compulsory mixer mixer;
For dry mixing, mixing time than not be extended fibers about 1 minute;
For the wet mix, stirring time than the mortar without fibers extend about 30 seconds.
4, indicating
In order to ensure fiber in mortar mixed evenly, to ensure that every tank mortar mixing time.
If you can not meet the above method or the use of mixing difficulties, please seek technical advice to our company or to the relevant professional advice.
3, "SISIYUAN" Fiber Precautions
Only as a secondary reinforcement, not a substitute for structural strengthening of material (such as the strengthening of reinforced), not to be used separately by powerful external forces to solve the impact of settlement and cracking of the occasion, not because of the use of fiber reduced the size of main structure, the use of fiber construction and maintenance are still strictly in accordance with relevant state regulations and customary closing conditions.
4, "SISIYUAN" fiber storage conditions
To prevent prolonged exposure to sunlight.
