We all know that GRC components are generally used for outdoor exterior wall engineering. However, some outdoor environmental factors can affect the compressive strength of Shandong GRC members. Therefore, grasp the correct maintenance and upkeep method of GRC components. Now let me take you to understand!
Regularly maintain and maintain surface waterproof materials or paint. Prevent water loss. On the other hand, it is to avoid contact with air, which can cause rust in the external building steel bars and lose practical value.
There is a lot of dirt on the surface of GRC. We can terminate the cleaning by using a high-pressure water pump below 80, but the compressive strength cannot be too high, otherwise it will damage the parts. Attention should be paid to terminating such cleaning regulations on time to avoid direct sunlight.
The specific cement-based material should have good flowability and process performance, and the moisture content should be higher than 25. But the higher the moisture content, the more impact it has on crack resistance.
During the production process, concrete needs to be mixed to make it come into contact with water, resulting in a hydration reaction and the production of cement mortar. Part of the concrete is not prone to producing fly ash cement, and the water that should have participated in the hydration reaction will increase the air holes and reduce the crack resistance of GRC components. Conversely, reducing porosity can improve crack resistance.
The adhesive properties formed by different cement grades are different, and the porosity and total number of capillaries are also different. And its crack resistance is also different. The crack resistance of ordinary Portland cement is better than that of cement mixed with fly ash and volcanic magma. The crack resistance of aluminate cement is better than that of ordinary cinnamate concrete.
