Paving blocks were produced and subjected to compression strength, water absorption and porosity tests.
Mathematical models of the flexural strength, water absorption and density were developed and statistically validated.
The bricks were then tested for mechanical strength, water absorption freeze-thaw resistance.
The physical properties that are discussed include strength, water content and thermal stability.
Compressive strength, flexural strength, water absorption and drying shrinkage of the hardened composites were investigated.
Compressive strength, splitting tensile strength, water absorption and chloride ion penetration of the hardened composites were investigated.
The latters were then subjected to the main qualification tests (splitting tensile strength, water absorption, leaching test).
Compressive strength, water absorption, under-pressure water penetration depth, and elasticity modulus tests were done on the specimens.
The variables to be determined were film opacity, film thickness, tensile strength, water vapor permeability, elasticity and film solubility.
The properties considered included, immediate-bearing index, unconfined compressive strength, indirect tensile strength, water permeability and frost-heave.
Tests were performed for compressive strength, water absorption and rapid chloride permeability at the age of 28 and 91 days.
