Portland is a type of cement. The other commonly offered type is masonry cement. Rizal is a product of Cemex.

Sa CHB best way to test strength is pag umpugin mo sila. Pag nabasag/na damage, konti cement content and mahina yun. Also look out for the shape. Most backyard makers have deformed blocks na wala sa hulog. Magastos sa palitada kasi papantayin ng mason yung irregularities.
