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...

Abstract

The invention discloses a sealing material for concrete impermeability tests and a test method thereof. The sealing material comprises butter and cement. Cement and butter are heated in a baking oven with a temperature of 50 to 80 DEG C according to a weight ratio of 2.2:1 or 2:1 so as to melt and evenly mix the butter and cement. In the impermeability tests, when the room temperature is higher or equal to 15 DEG C, the weight ratio of cement to butter is 2.2:1; and when the room temperature is lower than 15 DEG C and is higher than 5 DEG C at the same time, the weight ratio of cement to butter is 2:1. The impermeability performance of the provided sealing material is prominently better than that of conventional sealing materials.

Description

technical field [0001] The invention relates to a sealing material for concrete anti-seepage test and a test method thereof. Background technique [0002] In the construction of water conservancy projects, concrete works occupy a large proportion. How to improve the durability of concrete and prolong the service life of concrete structures has become the focus of water conservancy project construction. Whether the impermeability of concrete is good or not determines the durability of concrete to a large extent. The durability of concrete with high impermeability is good, and the impermeability also directly affects the frost resistance and erosion resistance of concrete. An important link in the concrete impermeability test is to seal the concrete specimen. There are several sealing methods, but these methods are cumbersome. Although the method of pressurizing the test piece by the instrument has become more and more intelligent, the sealing of the test piece is still diffi...
