The Effect of Different Proportioning Schemes of Permeable Blocks on Permeability
Permeable blocks are the new environmentally friendly building materials born from the maintenance of urban ecological balance, which have the characteristics of sound absorption and noise reduction, heat island effect mitigation, rainwater quality purification, and landscaping, etc. Mainly used in urban squares and urban road paving. Permeable block of different proportioning schemes on the impact of product permeability, here are analysis following:
Different proportioning schemes produce different permeability and strength of the block products. The main factor affecting the permeability of permeable block is still the raw material grading, under the same conditions of the grading number of all levels of the same proportion of the same permeability can be obtained, less granular fine aggregate formulated by the permeable block performance is significantly better than more granular fine aggregate. This is because in the continuous grading of each grain level fill each other, the pores of the finer aggregates with more grains are less than those of the finer aggregates with fewer grains. And because the surface area of more granular fine aggregate is larger than that of less granular fine aggregate, which increases the amount of cement, making the continuous grading of more granular fine aggregate permeable block within the less connected holes, permeability is also poor.
Environmental protection permeable block machine production line plays a pivotal role in urban construction, the reason why the machine produces different blocks-- on the one hand, the role of the mould, on the other hand, the role of different proportioning schemes.
QGM in 2014 fully acquisition of Germany Zenith, and in 2016 acquired the Austrian high-end mould company, QGM has formed three series of block making machines, is an integrated solution operator of block making, which can meet most needs of the market and has a number of block making proportioning schemes and related technology so that can greatly for clients to solve the problems encountered in daily production and help clients understand the details of the proportioning scheme.
