1. With the large-scale development of infrastructure and major projects, the reserves of natural sand have decreased sharply. Manufactured sand has become an alternative aggregate to river sand due to its good performance and large reserves. 2. As a substitute for natural sand, manufactured sand reduces the large-scale environmental damage caused by river sand mining. 3. Using manufactured sand as the fine aggregate for concrete and conducting research on manufactured sand concrete technology effectively solves the problems in major projects

1. The heat sink of the LED floodlight is made of finned pure aluminum sheets, which have good heat transfer and conduction effects. It is manufactured using the FIN-clamping process with advanced technical design. 2. The contact area between the aluminum substrate and the heat sink of the LED floodlight is increased and they are in close contact without gaps, which reduces the air thermal resistance and speeds up the heat conduction of the aluminum substrate.
3. Each fin of the LED floodlight has air holes, and the fins are connected to form a circular air convection channel, which allows the high-temperature heat inside the lamp to be conducted out through air convection or heat sinking. 4. The power supply of the LED floodlight is placed in an insulated and flame-retardant circular power supply box, which meets safety regulations and ensures safe use. There are air convection holes at the top and bottom, which allow the heat generated by the power supply to be diffused into the air through air convection, reducing the internal temperature of the power supply, extending its service life, and ensuring the service time of the lamp. 5. The structure of the LED floodlight body is lightweight, only 60% - 70% of the weight of turned aluminum. There is no need to fill the power supply box with thermal conductive silicone, which not only reduces the production and maintenance costs of the enterprise but also reduces the transportation costs. 5. The structural parts of the heat sink of the LED floodlight have applied for multiple technical protections
7. Suitable for: Panoramic lighting of interior and exterior walls in lighting projects, commercial venues, airports, subways, elevated overpasses, billboards, stadiums, architectural landmarks, etc.
- The project lighting lamps, 6 - meter stadium lamps, LED industrial and mining lamps, and floodlights use American CREE lamp beads, which have the characteristics of high thermal conductivity, small light attenuation, pure light color, and no double - image.
- The heat dissipation of the project lighting lamps, 6 - meter stadium lamps, LED industrial and mining lamps, and floodlights is integrated with the lamp housing design, which effectively conducts and diffuses heat, thereby reducing the temperature inside the lamp and ensuring a service life of 50,000 hours for the LED light source. Calculated by lighting for 11 - 12 hours a day, the LED industrial and mining lamps do not need to be replaced for 12 years.
- The surface of the project lighting lamps, 6 - meter stadium lamps, LED industrial and mining lamps, and floodlights is treated with anodic oxidation for anti - corrosion, with a compact and beautiful structure. It has good anti - corrosion, waterproof, and dust - proof performance.
- The project lighting lamps, 6 - meter stadium lamps, LED industrial and mining lamps, and floodlights have obvious energy - saving effects. They use high - power LED light sources equipped with Taiwan Mean Well power supplies, which can save more than 60% energy compared with sodium lamps.
- The project lighting lamps, 6 - meter stadium lamps, LED industrial and mining lamps, and floodlights are green and environmentally friendly, containing no pollution elements such as lead and mercury, and causing no pollution to the environment.
- The project lighting lamps, 6 - meter stadium lamps, LED industrial and mining lamps, and floodlights have good color rendering, presenting the real color of objects more vividly. Various light colors are available to meet the needs of different environments. The traditional lamps with too high or too low color temperature may cause depression, while these lamps make the vision more comfortable and improve the work efficiency of workers.
- The project lighting lamps, 6 - meter stadium lamps, LED industrial and mining lamps, and floodlights use Mean Well constant - current and constant - voltage power supplies, with a wide applicable voltage range (AC85V - 265V). They overcome the power grid, noise pollution caused by the ballast and the instability of the light, avoiding the irritation and fatigue to the eyes during work.
- The fin - type LED floodlights have a good decorative effect. Using surface treatment technology, the appearance can be in a variety of colors. They are easy to install and disassemble, and are applicable.
Decompose the dry - wet cycle process of concrete into drying and wetting processes, and study the change rules of relative humidity at different depths, the rules of water evaporation/absorption, and the influence of chloride ions on water transport during the dry - wet process. The results show that: Measuring the evaporation/absorption water volume and relative humidity during the dry - wet process of concrete can reasonably formulate the dry - wet cycle system and carry out the conversion of the acceleration ratio between indoor tests and on - site environments; In the early stage of dry - wet cycle, the water loss/absorption rate of concrete is high and then decreases significantly; The drying time determines the deterioration depth of concrete. When formulating the dry - wet cycle system, it is advisable to extend the drying time and shorten the wetting time; The presence of ions does not affect the water transport mode of concrete, but will greatly reduce its capillary adsorption and diffusion transport effects.
