Abstract
The utility model relates to an anti-cracking leak-proof reinforced fiber for concrete/mortar. The utility model consists of a cortex with a bi-component core composite structure and an inner core. A diameter range of fiber is from 0.04mm to 0.06 mm. A length range is from 2 mm to 2.5 mm. The combination form of the fiber is a pinch of tows with a plurality of tows accumulated in the same direction. The utility model is high in tensile strength and large in elastic modulus. The tensile strength can achieve 326 MPa, fifteen percents higher than the polypropylene fiber. The elastic modulus is 6140 MPa, seventy percents higher than the polypropylene single fiber. Through activating treatment on the surface, the utility model is characterized in power acid and alkalin resistance, good in dispersivity, light in specific gravity and antiaging. When the fiber is stirred with concrete and mortar, the fiber has no caking, an even distribution, a good affinity with the cement, low water retaining rate and other excellent performance.
Description
Technical field:
The utility model relates to a kind of fortifying fibre for building, is specifically related to a kind of impervious fortifying fibre of cracking resistance that is used for concrete, mortar, belongs to the International Classification of Patents E04C5/01 field that " is used for concrete reinforcement ".
Background technology:
The concrete that construction work is used, mortar, often along with season, variation of temperature and ftracture, phenomenon such as infiltration, have influence on workmanship and application life.Become insoluble for a long time hard nut to crack.In order to increase the intensity of concrete structure, what have is provided with reinforcing bar in concrete structure, promptly do aggregate with reinforcing bar.Though improved whole tension, shearing resistance, compressive strength like this, the intensity of aspects such as the cracking resistance of concrete surface layer, shock resistance, antidetonation, impervious water is still lower, and cost is very high, and steel fibre is used for concrete/mortar and easily gets rusty.Some engineering specialist makes reinforcement material with glass fiber, though improved tensile strength, fracture elongation only have about 5% in mix stirring easy fracture, also acid and alkali-resistance not.
Summary of the invention:
The purpose of this utility model is to provide a kind of tensile strength height, the impervious fortifying fibre of the cracking resistance that is used for concrete/mortar that modulus of elasticity is big.
The technical solution of the utility model is as follows:
Concrete/impervious the fortifying fibre of mortar cracking resistance is made up of with the cortex and the inner core of core composite construction bi-component; The diameter range of fiber is 0.04-0.06mm, and length range is 2-2.5mm.
The combination form of fiber: pinch shape tow that presents many accumulations, direction unanimity.
The utility model is used for the impervious fortifying fibre of cracking resistance of concrete/mortar, the tensile strength height, and modulus of elasticity is big.Its tensile strength can reach 326MPa, surpasses 15% of polypropylene fibre.Modulus of elasticity is 6140MPa, surpasses polypropylene filamentary 70%.Activation processing through the surface has that anti acid alkali performance is strong, good dispersion, light specific gravity, an advantage such as anti-aging.This fiber product and concrete, not conglomeration of fiber when mortar stirs, be evenly distributed and have with the cement compatibility good, the low excellent properties that waits of water retention.Hydraulic engineering, underground waterproof engineering, tunnel, subway engineering, airfield runway and machine level ground engineering, bridges in highway engineering be can be widely used in, residence building roofing, body of wall, pond, washroom, decorative paint etc. reached.All can control the crack growth that plasticizing contraction, drying shrinkage and the variations in temperature factor of concrete/mortar cause very effectively, can improve anti-permeability performance, shock resistance and the shock resistance of concrete/mortar greatly, play enhancing, firm, durable remarkable effect.
Description of drawings:
Fig. 1 is the single schematic cross-sectional view of the utility model fiber;
Fig. 2 is the outline drawing of single fiber;
The schematic diagram of pinch shape tow of the many accumulations that Fig. 3 presents for fiber combinations, direction unanimity.
Among the figure: 1, inner core, 2, cortex.
The specific embodiment:
The impervious fortifying fibre of cracking resistance that is used for concrete/mortar, it is strong synthetic fibre building materials fiber, its bi-component is selected from the composition combination of core composite construction: polyethylene/polyester, polypropylene/polyester, polyethylene/polypropylene, 4 kinds of polypropylene/nylon are about to two kinds of different high molecular polymers and are compounded in the same ultimate fibre.Its specification has 15D * 19mm, 10D * 19mm, 6D * 9mm, 3D * 3mm.Its fusing point＞160 ℃, tensile strength＞320MPa, modulus of elasticity＞6000Mpa.
In use, every cube of concrete/mortar is admixed strong synthetic fibre building materials fiber 0.8-1.2Kg generally speaking, and is unsuitable too many.In proportion strong synthetic fibre building materials fiber is put in concrete/mortar, continued to stir 2-3 minute, make strong synthetic fibre building materials fiber admix not easy fracture in concrete/mortar, not conglomeration can effectively be evenly distributed in concrete/every nook and cranny, mortar ground, uses very convenient.
Use the concrete/mortar of the utility model fiber, after tested, its tensile strength is than nearly one times of other building materials fiber height.Show through test of many times: its antidetonation, cracking resistance, impervious, impact strength are much higher than the like product technical indicator, are the concrete/mortar reinforcing material that has effect now.
