Hydraulic bricks have good permeability, air permeability, and water retention. It has multiple functions such as cooling, noise reduction, climate regulation, improving air quality, and maintaining surface water circulation. Widely used in urban sidewalks, stations, pedestrian streets, apartment parking lots, airports and other places, it has become a popular paving stone among the public.
Guidelines for Material Selection in Production
The selection of materials is crucial for producing high-strength hydraulic bricks, which are made from stone powder. The transportation of materials depends on whether the thickness is appropriate. Is there any soil. Below is an introduction on how to choose materials.
1. When the materials arrive, you need to grab them by hand and hold them in your hand. Generally, materials with appropriate thickness will not feel too tight when held in the hand, and materials that are too coarse will not clump together when held in the hand. Too fine hydraulic bricks will be too soft and disappear with just one grip.
2. Put the material into the mixer and add an appropriate amount of aggregate stones (usually in a ratio of 4:1). Let the mixer stir a few times before adding water (the ratio of water to stones is 10:1) and then cement. Mix cement and stone thoroughly. After stirring evenly, grab it with your hand. As long as it is formed from a single stone. And having a damp feeling in your hands is enough.
Hydraulic bricks belong to a type of wear-resistant brick, which has a small volume on the brick surface, simple color of the brick body, and often adopts the form of concave and convex surfaces. This type of hydraulic brick has the characteristics of anti slip, wear-resistant, and easy repair.
