Carborundum, also known as refractory sand or steel shot, boasts high hardness and high-temperature resistance, making it widely applicable as an abrasive or in the production of hardware, glass, semiconductors, and more. Additionally, it is used for surfaces that require wear and impact resistance with reduced dust generation, such as parking lots, factories, workshops, and more. During construction, every step must be carefully executed to ensure the quality of the flooring. For specific construction techniques, please refer to the following text:
1. Basic concrete pouring
The preparatory work for the grassroots concrete pumping process should be thoroughly done to ensure continuous pouring. Simultaneously, a concrete setting time test must be conducted to beforehand understand the time from initial to final setting of the concrete, making it suitable for the necessary construction sequence time of the diamond sand surface layer. During concrete pouring, mark the boundary with pre-buried steel channels, fill and compact the concrete between the two channels, then use a trowel to level the surface against the steel channels. After the concrete is in a non-flowing state, remove the fixed nuts, remove the steel channels, and immediately fill, compact, and smooth the concrete with a trowel, then hand it over to the surface layer construction team for work.

2. Surface Construction
Gritstone surface layer is a pre-mixed product primarily composed of tightly packed high-strength aggregates and special additive formulations. The application process occurs during the initial setting stage of freshly poured concrete, where the product is applied in two stages followed by specialized mechanical operations. The formed surface layer, when integrated with the base concrete, offers high strength, hardness, and non-dust properties.
3. The main construction processes include: 1) Remove froth, first application: Sprinkle the specified amount of 2/3 of the product before the base concrete is 50-60% dry, compact and abrade with a polishing machine to allow it to penetrate the concrete surface. 2) Detailed leveling, second application: After a certain period, sprinkle the remaining 1/3 in the same manner, and use a polishing machine and a metal trowel for overall smoothing. 3) Troweling operation: Perform at least three passes of blade-type polishing based on the concrete curing condition. 4) Surface finishing: Complete with mechanical or hand troweling. 5) Maintenance: Apply maintenance agent according to weather conditions. 6) Cutting of expansion joints and filling with PU glue. 7) Waxing and handover.
In summary, it's crucial to be aware of the concrete freezing time, select appropriate surface materials, and remind everyone of the importance of finished product protection. By addressing these points, the entire construction process can be better completed. The editor also believes that with the superior properties of金刚砂 itself, it will also have a broader application and greater value in the future.
