Description

Three-in-one composition and its use

The invention relates to a three-in-one composition and its application, belonging to the technical field of building materials.

Buildings 10 such as general houses and bridges mainly use steel bars 11 as the skeleton and cover them with concrete 12 grouting (see Figures 1 and 2). After the concrete 12 dries, the buildings 10 can obtain a fixed shape. Objects include beams, walls, floors of houses, beams, columns, piers of bridges and so on; Cross bracing, so it is not easy to fall, and the steel bar 11 itself can withstand considerable pressure and tension, and has appropriate elasticity, so that the concrete 12 has improved pressure resistance and vibration resistance, thereby improving the strength of the building 10 .

As we all know, concrete 12 itself has hard and brittle characteristics. Once it is hit by an external force, it is easy to crack, and the sand, stone, carbon ash, etc. in the composition will be broken into pieces and fall (see Figure 3-4). When used on the object 10, in case an earthquake occurs, although the steel bar 11 increases its strength, when the earthquake force exceeds the strong strength that the building 10 can bear, the concrete 12 will first crack and fall, and when the concrete 12 falls, it will be exposed. Go out steel bar 11, and steel bar 11 will be bent because there is no concrete 12 cladding support all around, so that the house is toppled into ruins, and the bridge will break and fall.

After the concrete 12 is damaged by external force, it will become fragments or sand and gravel particles will separate and fall, and the broken concrete will be irregular in shape and form sharp protruding corners (see Figure 3 and 6), which often cause accidental injuries accidents, so its safety is worth considering.

Buildings will cause cracks and the main reason for the loss of concrete is that although sandstone, cement, carbon ash, etc. are mixed and solidified, they can also be combined with each other (Figure 5), once damaged, the elements of the composition will interact with each other. Unable to be combined into one again, it must become fragments and fall apart (Fig. 6).

The raw materials of concrete mainly come from sand and gravel taken from rivers and hillsides. The sand and gravel are not inexhaustible and inexhaustible. The mining of sand and gravel will cause damage to the natural environment and affect the ecological balance. The severity should also be taken into consideration. focus on.

Generally, the pavement of asphalt roads is paved on the ground surface by mixing asphalt with sand and gravel. Compared with cement pavement, it can increase the grip of tires and improve driving safety. However, after a period of use, the asphalt will change from sand The surface of the stone peels off, exposing the sand and gravel, so that the tire is directly in contact with the sand and gravel, which affects the grip of the tire and driving safety, and the tire wear rate will also increase.

The number of waste tires in the world is increasing day by day, but it is difficult to properly handle and recycle, thus causing environmental pollution; the accumulation of rainwater in the tires promotes the breeding of mosquitoes and becomes the main cause of infectious diseases; the current treatment of waste tires is often to crush them , processed and made into recycled products, but the recycled products still have the problem of environmental pollution.

The purpose of the present invention is to provide a three-in-one composition and its application, which is mainly formed by mixing and consolidating steel wire, fiber thread and rubber. Stirring and mixing, it can be used in buildings, or mixed with gravel asphalt, can be used to pave roads; the three-in-one composition can improve the bonding strength with concrete, with proper elasticity, and then cooperate with steel bars to make buildings have proper elasticity, Become a buffer medium between sand and gravel. Under the same condition of bearing unit pressure, it can effectively improve the seismic strength of buildings and reduce their cracks.

In the three-in-one composition, at least one end of the steel wire and fiber wire contained in the composition is exposed on the rubber surface, and can be fully bonded together with the surface of sand and gravel and cement as a bonding medium. When used in buildings, even if cracks occur, due to the bonding between the steel wire and the fiber thread, the falling of fragments will be reduced, thus effectively improving its safety.

The object of the present invention is achieved like this: the three-in-one composition of the present invention is mainly mixed and consolidated by steel wire, fiber thread and rubber, and at least one end of the two ends of the steel wire and fiber thread protrudes from the rubber surface, and the rubber Is irregular arbitrary shape. Rubber is cut into pieces from waste tires, and then shredded into irregular pieces by a shredder. The three-in-one composition is uniformly mixed with concrete, sand and stone in the following proportions and can be used in buildings:

Three-in-one composition: 120-240kg 5.31-10.62%

Concrete: 140-160kg 6.20-70.8%

Sand: 1100-1000kg 48.67-44.25%

Stone: 900-860kg 39.82-38.05%

The three-in-one composition is mixed with sand, stone and asphalt according to the following proportions, and can be laid on the road surface:

Three-in-one composition: 40-80kg 5.31-10.62%

Sand: 350-400kg 48.87-51.28%

Stone: 300-250kg 38.46-32.05%

Asphalt: 90-50kg 11.54-6.41%

Example 1

Referring to Fig. 7, the three-in-one composition 20 of the present invention mainly contains steel wire 21, fiber wire 22 and rubber 23 and is fixed as one, and at least one end of the steel wire 21 and fiber wire 22 protrudes from the surface of rubber 23; And the rubber 23 is irregular arbitrary shape.

The above-mentioned three-in-one composition 20 is mainly taken from the waste tires used by automobiles, which are first cut into blocks, and crushed into irregularly shaped pieces by a crusher. Since the waste tires themselves are made of rubber, steel wire, and fiber wire Consolidated, in the case of cutting into blocks and crushing, the steel wire and fiber wire are also cut off, part of which is consolidated inside the rubber fragment, and part of it is exposed outside the surface of the rubber fragment, so this The inventive three-in-one composition 20 naturally has many protruding steel and fiber threads. The utilization of waste tires in the invention not only solves the problem of recycling waste rubber tires, but also solves the problem of environmental pollution.

Referring to Fig. 8, because the rubber 23 in the three-in-one composition 20 of the present invention has elasticity, its surface has protruding steel wire 21 and fiber thread 22 again, after it is mixed with concrete 12 by sub-determined ratio, can make concrete Evenly distributed in 12, and steel wire 21, fiber wire 22 and the binder cement in concrete 12 are fully bonded into one, wherein rubber 23 is interposed between stones and sand in concrete 12, not only steel wire 21, The fiber thread 22 is effectively combined with cement and stone, and the rubber 23 has elastic cushioning performance, so that the concrete 12 also has proper elasticity and cushioning performance. Part of the shock force can be absorbed and buffered by the rubber 23, so the probability of building cracks is greatly reduced.

Referring to Fig. 9, when the building is subjected to the effect of external force, when exceeding the combined strength of the three-in-one composition 20 of the present invention and the concrete 12, since there are steel wires 21, fiber threads 22 and cement binder in the concrete 12 on the surface of the composition 20 And sand and stone are firmly combined together, even if cracks occur, they will not fall into pieces and fall, only fine sand or only cracks will fall from the cracks, while the concrete still maintains a mutual connection relationship, correspondingly The safety of the building is improved, the injury accidents caused by the falling of the sharp block are reduced, and at the same time, the risk of the building breaking and collapsing is also reduced.

Example 2

The three-in-one composition 20 of the present invention can be used for laying road surfaces, and the three-in-one composition 20 of the present invention is uniformly mixed with sand, stone, and asphalt in a predetermined ratio, so that the surface of the rubber 23 of the three-in-one composition 20 The steel wire 21, the fiber thread 22 and the sand and the stone are infiltrated by asphalt and closely bonded together.

The commonly used ratio is: three-in-one composition: 40 kg 5.13%

Asphalt: 90 kg 11.54%

Sand: 350 kg 44.87%

Stone: 300 kg 38.46%

The asphalt road paved according to the above ratio, because the three-in-one composition between the sand and gravel effectively increases the elasticity, even if the asphalt peels off from the surface after a period of use, the three-in-one composition is still combined between the sand and the stone. When the car is driving on the road, especially when the road surface is wet and slippery in rainy days, the gripping ability of the tires can still be increased, thus improving the stability of driving and braking, effectively improving its safety, and at the same time effectively reducing the wear and tear of the tires. wear rate, prolonging the service life of the tire.
