Description of the invention (4) The flow chart of the method for producing high-pressure floor tiles and red bricks, the main steps of which are as follows: crush the recycled construction waste concrete and bricks as recycled aggregates, add sand, cement, water and Silica ash or fly ash is mixed and stirred, filled in a model to be pressurized, and then dried in the shade for health, to obtain the finished products of recycled high-pressure floor tiles and red bricks. Please refer to the first step in the flowchart of the method for preparing regenerated high-pressure floor tiles and red bricks using waste concrete and bricks according to the present invention, as shown in Fig. 1. The particle size of construction waste concrete or bricks just recovered from various places is usually too large to be used as the aggregate for the manufacture of concrete products. Therefore, the recycled concrete or bricks must be crushed with a general jaw crusher. First, set the jaw crusher opening to 8 cm for coarse crushing of waste concrete or obstructions. The coarse aggregate obtained after the coarse crushing is further finely crushed with a jaw crusher set to an opening of 1 cm. The particle size of the recycled aggregate obtained after fine crushing is mostly between 3/8 inch and 1/100 mesh. Among them, the composition ratio of the recycled aggregate of waste concrete is shown in the first figure and the attached table. The recycled aggregates of the waste concrete or bricks obtained from the first step can be used to make recycled high-pressure floor tiles or red bricks in accordance with the following steps regardless of their particle size after being finely crushed. Please refer to FIG. 1 for the present invention. The second step in the flowchart of a method for preparing recycled high-pressure floor tiles and red obstacles by using waste concrete and bricks.

The compressive strength of the invention (5) or higher standards (> 408kgf / cm2), it is necessary to control the water-cement ratio (W / C, water / cement) of the water to cement is preferably maintained below 0.43, but to avoid excessive shrinkage (shrinkage), latent variables ( creep) and hydration heat, so the reduction of the water-cement ratio (W / C) can usually be achieved by using water-reducing admixture in addition to increasing the amount of cement. In addition, in order to reduce the amount of cement used to reduce costs, and increase the compressive strength and water absorption of high-pressure floor tiles, low-cost concentrated silica ash or fly ash can also be added (as shown in the second figure). When an appropriate amount of concentrated silica ash or fly ash is added, the mixing ratio of the recycled aggregate, cement, water, natural sand, and silica ash (or fly ash) is about 130: 40: 20: 50: 6, and its water-cement ratio (W / C) is controlled below 0.5, which can make the finished high-pressure floor tiles meet the compressive strength (> 408kgf / cm2) of CNS 13296 Grade B or higher. On the other hand, if recycled aggregates made from discarded bricks are used to prepare recycled red bricks, the recycled aggregates must be mixed with cement, water, and natural sand at a ratio of about 100: 40 ... 20:50 and stirred When made into fresh concrete, its water-cement ratio (W / C) is usually kept below 0.5, so that the recycled red bricks made meet the compressive strength of general red bricks (> 282kgf / cm2). Please refer to Figure 1 Shows the third and fourth steps in the flowchart of the method for preparing recycled high-pressure floor tiles and red bricks by using waste concrete and bricks according to the present invention. After the fresh concrete is mixed and stirred, it is filled in a brick-making model and added at a pressure of 150 kgf / cm2. Press to make high pressure floor tiles or red bricks. In order to completely dry the high-pressure floor tile or red block to increase its compressive strength, it should be allowed to dry in the shade for more than 28 days. After the above steps, the finished products of recycled high-pressure floor tiles or red bricks made of construction waste concrete and bricks can be obtained.

Description of the invention (6) It should be added that, because the construction waste concrete and bricks are used building materials, their physical and chemical properties are tested according to CNS488 specific gravity and water absorption rate, CNS4 * 90 test Loss ratio of Los Angeles, CNS-A303, 3034 was used to test the rate of sodium sulfate health loss. First, the definition of water absorption is: the amount of water absorbed when the dry aggregate reaches the surface dry and saturated internal water absorption. Its unit is expressed by weight percentage. The greater the water absorption, the higher the porosity of the aggregate. When mixed with water The more water is required, and the durability is worse when subjected to thermal expansion and contraction, and it is easier to shrink and crack. The Los Angeles abrasion rate test is mainly used to test the abrasion resistance of coarse aggregates (there is no suitable method to measure the abrasion resistance of ultra-fine aggregates). The method is: Dry to constant weight in an oven at 110 ° C, (2) weigh 500 g of coarse aggregate after drying according to the specified grade, and (3) weigh the sample with a diameter of 47.6 mm and a weight of 44. Twelve grams of steel balls were added to the Los Angeles testing machine at the same time, and the rotation was 500 to 30 to 33 revolutions per minute. When the testing machine rotates, ‘pay attention to balance’ to get a uniform speed. After 500 revolutions, pour out the sample, and then use a sieve of No. 12 for sieve analysis. Those who can pass the sieve of No. 12 are regarded as the amount of wear. Generally, the wear rate of aggregate cannot exceed 50%. In addition, the experiment of the rate of sodium loss in health is to immerse the aggregate in a sodium or magnesium sulfate solution and then dry it, and then perform the test five times. For coarse aggregates, the weight loss is not more than 12% in sodium sulfate solution and not more than 10% in magnesium sulfate. As for the fine aggregate, the weight loss should not exceed 18% in the sodium sulfate solution and 15% in the surface sulfuric acid solution. After the above tests, it was found that regardless of the thickness of the recycled aggregate, except that its specific gravity is similar to that of natural aggregate (such as natural sand), its water absorption is too high, and its wear rate and fitness loss rate are also biased (such as Appendix Tables 2 to 2). Five paper standards are applicable to Chinese national standards (CNS> Α4 specifications (210X297 mm) —---- „-: --- install — (Please read the precautions on the back before filling the line staff of the Intellectual Property Bureau of the Ministry of Economic Affairs Printed by the consumer cooperative 558487 A7 * __B7_ V. Description of the invention (7)), so when the invention uses recycled aggregates to make high-pressure floor tiles, it is necessary to add some natural aggregates so that the high-pressure floor tiles made can meet the CNS 13296 Grade B or above (Notes · CNS 132% compressive strength standard: Grade A> 560kgf / cm2, Grade B> 408kgf / cm2, Grade C> 357kgf / cm2; Water absorption standard: Grade A < 5%, grade B < 6%, grade C < 7%). The method for preparing recycled high pressure floor tiles and red bricks by using waste concrete and bricks in the present invention is due to the use of recycled aggregates and silica ash (or fly ash), In order to reduce the use of natural aggregates and cement, the cost of manufacturing high-pressure floor tiles is reduced. And because of proper material ratio and water-cement ratio (W / C) regulation, the recycled high-pressure floor tiles of the present invention still have high pressure resistance (> 408kgf / cm2) and low water absorption rate of Class B above CNS 13296. (≪ 6%), and make the recycled red brick of the present invention have the compressive standard of general red brick (> 282kgf / cm2). Although the present invention has been disclosed in a preferred embodiment, it is not intended to limit the present invention. Anyone who is familiar with this skill can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope of the attached patent application. -^ --.--- install-- (please read the notes on the back before filling in page t) Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 558487 B7 V.
