文摘

Mechanical resistance depends on the type of the additive but not on the sand content. Capillarity absorption test is not appropriated to estimate earth based construction materials real durability. The total water absorbed test is suitable as earth based construction materials durability estimator. The freeze/thawing cycles test as it is defined in the Spanish Standards is not a good durability estimator. PC-8+GGBS additive obtained the best laboratory and real durability results.
