Problems solved by technology

However, due to the lack of strength-enhancing components, the bricks prepared according to the formula in this plan have a compressive strength of about 20Mpa, which cannot meet the requirements of municipal roads.
Similarly, the winter freezing and thawing problem of permeable bricks is not considered in this plan, so it is very easy to be damaged by freezing when laying in areas where freezing occurs in winter in the north
And the added nano-titanium dioxide has not been improved, the catalytic efficiency under visible light cannot reach the best, and the effect of removing haze and purifying water is not good due to the lack of adsorbents

Abstract

The invention relates to a water permeable brick with haze removal and water purification functions and a making method. The water permeable brick mainly comprises a surface layer with the haze removal function and a base layer with the water permeable function, and the surface layer is located on the upper portion of the base layer; the surface layer is prepared from, by weight, 80-100 parts of cement, 310-360 parts of coarse sand, 7-11 parts of silicon ash, 25-35 parts of water, 0.8-1.2 parts of water reducing agents, 3-6 parts of titanium dioxide and 1.5-4 parts of activated carbon; the base layer is prepared from, by weight, 90-110 parts of cement, 220-260 parts of stone, 70-110 parts of coarse sand, 8-12 parts of silicon ash, 8-12 parts of VAE, 0.1-0.4 part of polyethylene fibers, 25-35 parts of water and 0.8-1.2 parts of water reducing agents. According to the water permeable brick, novel substance components are designed, the good water purification and haze removal effects are achieved, and superhigh anti-freezing and thawing performance is achieved.

Description

technical field [0001] The invention relates to the related technical field of civil engineering, in particular to a permeable brick with haze removal and water purification functions and a manufacturing method thereof. Background technique [0002] In recent years, due to the substantial increase in the number of motor vehicles, air pollution in my country has become more and more serious. According to a report, less than 1% of the 500 largest cities in China meet the air quality standards recommended by the World Health Organization. Meanwhile, seven of the 10 most polluted cities in the world are in China. On January 4, 2014, the National Disaster Reduction Office and the Ministry of Civil Affairs included health-threatening haze weather in the 2013 natural disaster situation for the first time. [0003] Smog is mainly composed of three items: nitrogen oxides, sulfur dioxide and inhalable particulate matter. They combine with fog to make the sky instantly dark and gloom...
