Problems solved by technology

[0003] With the rapid development of industrialization in our country, more and more industrial wastes are produced. For example, due to a series of reasons such as limited mining technology and weak environmental protection awareness, a large amount of abandoned ore slag is produced in the quarry. Most of these ore slags are not in shape. Rules, small size and other reasons cannot be used as building materials, and the storage of waste slag requires a large amount of land, which seriously affects the country's soil resources and people's health
Another example is that tires are one of the main consumables of automobiles. Our country needs to eliminate a large number of waste tires every year. As we all know, tires, as stable organic industrial products, are difficult to decompose and take a long time to decompose. The decomposition process may produce toxic gases and endanger the environment.

Abstract

The invention provides impermeable concrete and a preparation method thereof. The impermeable concrete is prepared from the following components in parts by mass: 100 parts of cement, 30-50 parts of water, 120-150 parts of sand, 280-310 parts of gravel, 1-3 parts of a water reducing agent, 5-7 parts of nano silicon dioxide, 60-75 parts of rubber particles and 50-64 parts of granite stone powder. The impermeable concrete has strong impermeability, develops and utilizes nanoscale silicon dioxide, granite waste stone and waste tire rubber particles to become a potential huge market of green and environment-friendly buildings, and has remarkable economic, social and ecological benefits.

Description

technical field [0001] The invention belongs to the technical field of building anti-seepage, in particular to an anti-seepage concrete and a preparation method thereof. Background technique [0002] With the development of my country's economy, the field of underground space has developed rapidly, but the construction and maintenance of underground space are often accompanied by many problems. Underground space leakage is a problem in most underground projects. The erosion of water on underground structures has become one of the major problems restricting the development of underground space. How to effectively reduce groundwater leakage has become the subject of current research. At present, conventional anti-seepage measures are mostly used in China, such as adding polypropylene fibers to concrete to improve its impermeability. However, as people continue to increase the requirements for underground anti-seepage performance, today's anti-seepage technology is increasingly...
