Lower price pp plastic fiber 50mm and 65mm length concrete fiber for reinforcement of concrete and mortar

use:
1. Dosage: It is recommended that the volume dosage of imitation steel fiber be 0.3%-0.9%, that is, the dosage per cubic concrete is 3kg--9kg.
2. Length selection: general anti-cracking reinforced concrete is 30mm-50mm; 20mm-30mm is used to add to shotcrete.
3. Mix ratio design: It is not necessary to change the gradation ratio parameters of concrete for general application. You can refer to "Code for Steel Fiber Concrete Structure and Construction" CECS38:92. For special applications, selection and design require testing. Considering that concrete will cause tiny cracks due to factors such as drying shrinkage, drying shrinkage, and temperature changes, 1kg of monofilament ultrafine fibers can be added to the concrete for better results.
4. Mixer type selection: choose a double-shaft horizontal forced mixer.
5. Feeding and mixing process: First put in gravel, then put in anti-cracking tendons, then put in sand, stir to make the anti-cracking tendons fully disperse, then put in cement and water, and stir evenly according to the conventional process. It can also be constructed according to the sequence of conventional technology input, but the mixing time should be extended appropriately to make the anti-cracking reinforcement disperse evenly.
6. Forming and curing process: no special requirements, and the tape time can be extended as appropriate. When plastering, the concrete surface should be slightly passivated before proceeding to avoid it being brought out. The maintenance should still be carried out according to the requirements of ordinary concrete.
7. Packaging: regular packaging 1.0kg/bag, or according to user requirements.
