What is a cement flexural testing machine?
The cement flexural testing machine is a special equipment used to measure the flexural strength of cement mortar or concrete specimens. It is widely used in building materials laboratories, engineering quality inspection institutions and scientific research units. With the rapid development of the infrastructure industry, cement flexural testing machines, as a key tool for quality control, have recently become one of the hot topics in the industry. This article will combine the popular discussions on the Internet in the past 10 days to introduce in detail its definition, principles, technical parameters and purchase points.
1. Basic principles of cement flexural testing machine
The equipment applies a load to the cement specimen after standard curing through the three-point bending method, and records the maximum pressure value when the specimen breaks, thereby calculating the flexural strength. Its core components include loading frame, hydraulic system, sensors and control system.
| Core components | Function description |
|---|---|
| Loading frame | Provide rigid support to ensure uniform force |
| Hydraulic system | Smooth application of load, accuracy ±1% |
| High precision sensor | Real-time monitoring of pressure value with resolution 0.01kN |
2. Latest industry hot spots and technology trends
According to the analysis of the entire network data in the past 10 days, the following topics are the most popular:
| hot topics | focus of discussion | heat index |
|---|---|---|
| Intelligent testing machine | IoT data upload function | 85% |
| Implementation of new national standards | GB/T17671-2021 standard adaptation | 78% |
| Energy saving design | Standby power consumption＜50W | 62% |
3. Key purchasing technical parameters
By analyzing the latest sales data of e-commerce platforms, mainstream models need to pay attention to the following parameters:
| Parameter type | Standard range | High-end configuration |
|---|---|---|
| maximum load | 10kN | 20kN |
| Test accuracy | ±1%FS | ±0.5%FS |
| loading speed | 50N/s±5N/s | Programmable speed regulation |
4. Operation precautions
Recently, multiple technical forums have focused on the following operational points:
1. The test piece must be placed in the center, and the deviation does not exceed ±0.5mm.
2. The ambient temperature needs to be maintained at 20±2°C and the humidity >50%
3. Calibration is required once a month with a standard force measuring instrument.
4. The latest models of equipment are recommended to be equipped with automatic centering fixtures
5. Comparison of mainstream brands in the market
According to recent purchasing platform transaction data:
| brand | market share | Typical model |
|---|---|---|
| MTS | 28% | TestStarⅣ |
| Instron | 22% | 3367 series |
| Domestic first-line | 35% | WDW-10E |
The industry is currently developing towards intelligence and high precision. The latest equipment has integrated AI crack recognition technology and can automatically determine the fracture shape. It is recommended that users focus on the data traceability and third-party certification of the equipment when purchasing to ensure compliance with the latest national standards.
