Embodiment Construction
[0047] The present invention will be further described below in conjunction with the embodiments and accompanying drawings. Those skilled in the art should understand that the embodiments and accompanying drawings are only for better understanding of the present invention, and are not used to make any limitation.
[0048] The invention is mainly used to detect the waterproof performance of concrete after hardening, and finally determine its impermeability grade. The impermeability of concrete is expressed by the impermeability grade (p) or permeability coefficient. my country's standard adopts impermeability grade. The impermeability level is the maximum pressure that a standard specimen with an age of 28 days can withstand when tested according to the standard test method. Impervious concrete is divided into P4, P6, P8, P10, P12, >P12 according to the different anti-seepage pressure. Impermeable concrete refers to the concrete whose impermeability grade is equal to or great...
