SUNSHINE fibers are available in lengths from 0.50" (13mm) to 2.0" (50mm) and aspect ratios between 40 and 60. The fibers are manufactured either straight or deformed, and conform to ASTM A-820.
A low carbon, cold rolled sheet steel is used to produce SUNSHINE? product for concrete applications. This steel has ultimate tensile strengths from 50 to 120 ksi (345 to 828 MPa) and has sufficient ductility actually to permit 180° bends without rupture. Various stainless steel grades are used for the reinforcement of refractory concretes. Information on these grades for high-temperature applications is available upon request. SUNSHINE? fiber has more reinforcing elements per pound of product than any of its competitors. There are nominally 21,000 3/4" and 16,000 1" straight fibers per pound, as well as 9,000 1" (254mm) deformed fibers per pound.

Recommendations for construction technology
1.Grade of cement should be not less than NO.425 and the ratio of water and mortar should not be more than 0.5 2.The length of coarse material particles should not exceed 2/3 of that of steel fiber. 3.The mass of the steel fiber in steel fiber concreate should not be less than 0.5% and mormally it is to be selected between 05-2.0% 4.Sea water and sea sand shall not be used for making blocking steel fiber concrete and then addition of chlorate is stricty prohibited. 5.Inaddition, other materials to be used together for steel fiber concreate shall be in accordance with the specifications of the existing standards in relation to reinforcedconcrete. 6.The viscosity of steel fiber concreate can be datermined based on the requirements of normal engineering projects for common concrete. The value of its subside can be 200mm less than common concrete and its viscosity is the same as common concrete. 7.If there is no base material unde the surface layer and the bottom layer for the shrinking seams as flat seams and if it is in accodance with the following conditions,then: 1.The thicknessof the surface layer and the bottom layer before the reduction is less than 130mm:2.The thickness of the reinforced base layer is more thant that of the bottom layer,then the thickness can time the reduction coefficient 0.75,but not more than 50mm. |

Requirements for loading of materials 1.Steel fiber and other coarse materials are first put into a mixer and stirred for 30 seconds so that steel fiber shall be dispersed in the gravels to avoid agglomeration. 2.Sand and concrete is then put into a mixer for 30 second of dry stirring. 3.Water is then added into the rotating mixer with about 3 minutes of further stirring. Packing of products: The packing can be divided into 2 categories, either in paper cartons in an orderly manner or paper bags in an optional way based on customers’ requirement. The first is with a small volume and it is not easy to agglomerate and so it can be used by adding it directly into other materials thus reducing the cost of equipment and transportation for customers. |
