    To ensure the safety of personnel during the construction of concrete floors, we need to establish a comprehensive safety protection system that covers management and execution, as well as individuals and the environment. The following are specific and operational measures, which are divided into three levels: core safety principles, specific safety measures, and the safety management system. Prevention first: The core of all safety work is to identify risks in advance and eliminate them, rather than to remedy them afterwards. Full participation: Safety is not only the responsibility of safety officers. From project managers to operators, everyone is responsible for their own and others' safety. Continuous education: Through uninterrupted training and safety briefings, internalize safety norms into everyone's behavioral habits.   This is a direct barrier to protect workers and must be mandatory. Head: Wear a qualified safety helmet correctly and fasten the chin strap. Feet: Wear safety shoes (work shoes) that are resistant to impact, puncture and slip. Concrete workers are advised to wear high-top rubber boots to prevent cement corrosion. Eyes: When performing stirring, pumping, cutting or grinding operations, protective glasses or face masks must be worn. Breathing: When dust is generated during the handling, mixing, dry spreading and cutting and grinding of cement, a dust mask (such as N95 level or higher) must be worn. Hands: Wear chemical-resistant gloves (such as rubber or latex gloves) to prevent burns from cement and alkaline substances. At heights and edges: When working near the edge of floor slabs or openings, a full-body safety belt must be fastened. Before use, check whether the electrical circuits, insulation and protective covers are in good condition. It is strictly forbidden to insert hands or tools into the cylinder during operation. When cleaning or conducting maintenance, power must be cut off and a "Do Not Close" warning sign hung. A dedicated person should be assigned for supervision. Check whether the blade/grinding disc is installed firmly and whether the cable is damaged. When operating, hold your hands tightly to maintain your balance and prevent the machine from losing control and "jumping" to hurt people. The cables should be managed overhead to prevent them from being caught in machinery or run over by vehicles. Operators need to undergo professional training. Clear all obstacles along the equipment's movement path and set up a warning area to prevent people from approaching. All electric tools must be connected to the power supply through a leakage protection device (RCD). Cables must not be dragged on the ground or immersed in water. It is strictl y prohibited to use aged or damaged cables. Non-professional electricians are strictly prohibited from wiring or conducting maintenance. Opening and edge protection: All reserved openings, staircase entrances, and elevator shaft openings must be covered with firm covers or equipped with guardrails, and safety warning signs must be hung. Cement, sand, gravel and other materials should be neatly stacked, with a height not exceeding the specified limit and kept away from the slope. When manually moving heavy objects, use the correct posture (bend your knees and keep your back straight), and have two or more people cooperate to carry them to prevent sprains and injuries from being hit. Arrange the processes reasonably and minimize vertical cross operations as much as possible. When it is unavoidable, a solid safety isolation layer (such as a protective shed) must be set up, and a dedicated person should be assigned to coordinate and direct. When working at night or underground, ensure that the working surface is well-lit and leaves no dark corners. When conducting construction in enclosed Spaces such as basements, it is essential to ensure forced ventilation to prevent the accumulation of harmful gases and oxygen deficiency. When using chemicals such as concrete curing agents, release agents, and epoxy resins, it is necessary to read the Material Safety Data Sheet (MSDS). According to the MSDS requirements, wear the corresponding protective equipment (such as gas masks, chemical protective gloves, and goggles). Ensure good ventilation in the operation area. Safety and technical Briefing: Before the start of each day's work or the beginning of each new process, the team leader must provide a detailed explanation to all workers about the day's work content, potential hazards, preventive measures and emergency methods, and have all personnel sign for confirmation. Equipment inspection: Before starting work every day, the operator conducts a routine inspection of the machinery and equipment used to ensure they are in a safe condition. Appoint a full-time safety officer: The safety officer continuously patrols the site, promptly identifying and correcting unsafe behaviors (such as not wearing a safety helmet, operating in violation of regulations, etc.). Set up warning zones: In the operation areas of large equipment such as laser screed machines and pump trucks, clearly demarcate dangerous zones with warning tapes, and irrelevant personnel are not allowed to enter. Civilized construction: Clean up debris, oil stains and standing water on the ground in a timely manner, keep the passageways unobstructed, and reduce the risk of slipping and tripping. On-site first aid kits should be provided: Ensure that all items in the first aid kit are complete and effective, and placed in a conspicuous and easily accessible location. Clarify emergency procedures: All personnel should be familiar with the initial rescue procedures and alarm methods in the event of accidents such as electric shock, mechanical injury, and falls from heights. Conduct emergency drills: Regularly organize simple emergency drills, such as fire evacuation and casualty transportation. To ensure the safety of concrete floor construction, the key lies in eliminating "unsafe human behaviors" and "unsafe conditions of objects" in their infancy. This requires the joint efforts of strict management systems, continuous education and training, effective personal protection measures and real-time on-site supervision to form a closed-loop safety culture, thereby truly ensuring the life safety of every construction worker.   Note: The parameters provided in this document are for reference only and are not mandatory.

    Choosing the particle size and mix ratio of a colored dry-spread hardener (wear-resistant flooring material) essentially involves balancing workability, surface abrasion resistance, and the final color appearance. Because colored flooring requires extremely high visual consistency, the selection of particles is more stringent than for natural-colored flooring. The following is a detailed selection guide: Particle size directly determines the impact resistance and surface smoothness of the floor. Coarse Aggregate (1.5 – 3.5 mm): * Suitable for: Heavy industrial workshops, logistics channels with frequent forklift traffic. Leak inspection: Carefully inspect the entire hydraulic system, including: Features: High impact resistance, but in colored flooring, too many coarse particles can result in a slightly rough surface texture and are prone to "pinholes" during polishing. Fine aggregate (0.1 – 1.5 mm): * Suitable for: Commercial spaces, sidewalks, cleanrooms. Features: Extremely smooth surface, high color fidelity, easy to achieve a mirror finish. Optimal gradation scheme: * Typically uses a continuous gradation, i.e., 30%-40% coarse aggregate + 60%-70% medium-fine aggregate. This combination ensures tight interlocking between aggregates, reducing porosity. Colored dry-spread hardeners are typically pre-mixed from hardening aggregates, high-grade cement, pigment powder, and specialized additives. Aggregate to cementitious material ratio: * Recommended ratio is generally 1:1 to 1.5:1. If the aggregate ratio is too high (e.g., exceeding 2:1), the material's adhesion will decrease, and the colored flooring will be prone to peeling and flaking. Pigment content: * Typically 3% – 8% of total weight. Note: Pigments are fine powders. Excessive content (>10%) will reduce the strength of the surface and increase the risk of cracking; insufficient content will result in unsaturated color, making the underlying concrete color more visible. The amount of paint applied directly affects the depth and wear resistance of the colored flooring. Expected Load Recommended dosage (kg/m2) Construction Methods Light Load (Pedestrian walkways, light storage) 4.0 – 5.0 Manual spreading or light equipment Medium Load (Parking lots, production workshops) 5.0 – 7.0 Automatic spreading machine (spreads material in two stages) Heavy Load (Heavy machinery, unloading areas) 7.0 – 9.0 Specialized equipment must be used to ensure compaction. Colored concrete flooring is most susceptible to color difference, which is directly related to particle size and mixing ratio: Batch Control: Ensure that the hardener used in the same area is from the same batch and has the same mixing ratio. Even slight differences in particle size between different batches can lead to inconsistent light reflection. Two-Coat Application Method: * Apply 2/3 of the amount in the first coat, using the concrete moisture to wet it; Apply 1/3 of the amount in the second coat, specifically to fill in any sparse areas of color left from the first coat.   Use Nano Hardener: After construction, it is recommended to use a nano sealing and curing agent. It fills the tiny gaps between the aggregates, "locking in" the colored particles and improving color durability by more than 50%.   Note: The parameters provided in this document are for reference only and are not mandatory.
