Preventive measures for permeable brick defects
Disadvantage prevention measures for colorful pavement permeable bricks The economic level of our country is continuously improving, which is a certain degree of progress on the daily level of our people. Because of the acceleration of the urbanization process in China, the number of urban residents is constantly improving. Therefore, in order to better meet the daily needs of residents, we use pavement bricks for laying on the ground in parks and other entertainment places. Because the research and analysis of pavement bricks by professionals in our country can know that new pavement brick methods have also appeared in people's day, such as permeable bricks , grass planting bricks and interlocking block pavement bricks, their functional advantages are more obvious, The new style of pavement tiles is widely used in people's day.
As for pavement bricks, because of the different colors, China has presented a colorful way of pavement bricks. However, because of the difference in the materials used, it is extremely prone to the depth of the fabric in practice. At this time, in order to avoid this phenomenon in the production process of colorful pavement bricks, the nature of the cement and gravel aggregates used must be stable. During the production of the same batch of colorful concrete pavement bricks, a batch of cement of the same model must be used. And aggregates of the same layer and same color mine. Cement can only be stored for one month to prevent moisture. Agglomerated cement cannot be used, to avoid the appearance of potholes, matte, and uneven colors in colorful concrete pavement bricks. We should use the composition mineral pigments in the process of producing colorful pavement tiles. Various pigments can be matched with each other, but it should be determined through experiments, and the respective pigment content and the true color of the filler should be recorded for future comparison. Generally, the pigment content of the coloring layer is 3% to 5% of the cement content.
