The UNT series cement brick machine designed and produced by UNIK can produce permeable bricks, which are suitable for paving squares and roads. The permeable bricks can remove dust, absorb sound, reduce noise, and can also purify the environment, reuse waste, and save ecological resources. The main influencing factors of making permeable block paving from industrial waste residues include preparation methods, raw material cleaning processes, mixing processes, extrusion processes, and maintenance processes.
The green environmental protection block making equipment is large and medium-sized automatic equipment, and the water permeability and strength of brick products produced by different deployment methods are different. First of all, the factors that adversely affect the water permeability of permeable bricks are the different mix ratios of the overall surface layer. Under the same standard of gradation numbers, when the proportions of each mix are the same, a relatively large water permeability can be obtained, and there are relatively few fine stones in particle size distribution. The performance index of the prepared permeable brick is obviously better than that of more fine stones with particle size distribution. This is because in the continuous mix ratio, the particle size distributions fill each other, the porosity of fine stones with more particle size distribution is less than that of fine stones with less particle size distribution, and because the specific surface area of fine stones with more particle size distribution exceeds that of smaller particle size distribution The specific surface area of fine stones increases the amount of mortar used, making the permeable brick surface test blocks with more fine stones in the continuous mix ratio have fewer communicating holes and poor water permeability. There is also a blending ratio in the continuous blending ratio with relatively small particle size distribution. Secondly, the base layer of the permeable bricks produced by the green cement brick making machine is different, and the water permeability of the permeable bricks produced will also be different. The water-cement ratio, lime-sand ratio, and mix ratio also adversely affect the water permeability of the permeable brick base. In the design of parameters, the gradation changes quite a lot, while the water-cement ratio and lime-sand ratio only make small changes. It can be seen that the water permeability of the permeable brick base has changed a lot after the mix ratio is adjusted. It shows that the grading has a great influence on the base of the seepage brick. When the lime-sand ratio increases, the water permeability of the base of the permeable brick increases. This is because the water-cement ratio and the mix ratio have a negative impact on the water permeability of the base of the permeable brick. Using aggregates in two mix ratios for mixing, under the premise that the tensile strength of the material remains the same, the water permeability will increase significantly, and the increase rate is quite large. Obviously, the aggregate mix ratio is one of the key factors that adversely affect the water permeability. As the water-cement ratio decreases, the amount of water used decreases, the fluidity of the cement mortar decreases, the porosity in the mixture is less filled by the cement mortar, and the water permeability of the base of the permeable brick after extrusion will increase. Big improvement. The water permeability of permeable bricks increases with the decrease of water-cement ratio. The green environmental protection seepage brick production line equipment is one of the special equipment for new building materials of cement brick making machine. The seepage brick produced by this mechanical equipment plays a key role in buildings and roads with poor water permeability.
The base layer of permeable bricks with different mix ratios has a great influence on the overall water permeability. Because the increase in the content of coarse-grained stones increases the porosity in the test block and increases its water permeability. This is because the content of coarse-grained stones When it decreases, the specific surface of the stone decreases. When the amount of lime-sand specific stone is the same, the amount of mortar used will increase, and the scale of cement mortar will expand.
