Effect of Chemical Composition of Clay on Physical-Mechanical Properties of Clay Paving Blocks

Clay paving blocks made of natural, environmentally friendly materials have their own originality and colorful authenticity, but due to the complex technological production process, they are also relatively expensive products; therefore, environmental resistance properties strictly defined controlled by standards. The physical mechanical clay key factors aiming ensure longevity products long-term success in market. Therefore, ensuring high become a most crucial challenge for manufactures. This article considers parameters process manufacturing evaluates influence chemical composition three different types on blocks. Water absorption, linear shrinkage, freeze/thaw, acid resistance, transverse breaking load investigated. study reveals importance raw material selection provides concept main quality clay.
