cured floor is completed, how to judge whether it is qualified? We generally judge from three aspects: hardness, sealing, and gloss.
There are many ways to check whether the hardness reaches the standard. The simplest and most direct method is to use the key you carry with you to slide back and forth on the finished curing agent floor to see if there are scratches on the ground. You can also use a professional Mohs Use a hardness test pen to test. Usually, the hardness of the cured floor is between 7 and 8 on the Mohs scale.
Testing the sealing of the curing agent floor mainly tests the anti-seepage effect of the ground. Through the penetration of the sealing and curing material, the density of the concrete will be greatly improved. The test method is simpler. Oil or water can be sprinkled on the ground for sealing. According to the performance test, usually after curing treatment, the liquid will form water beads on the surface of the concrete, which is not easy to penetrate. It should be noted that all curing agent floors cannot achieve completely zero penetration, so if there is oil stains and corrosive liquids, they need to be cleaned within the cleaning interval.
Finally, there is the glossiness test. The most intuitive way is to judge it with the naked eye. Generally, the concrete surface is dull before construction, and the ground shows a mirror effect after completion. You can also use professional glossiness instruments to detect it.
