Comparative Analysis of the Compressive Strength of Concrete Hollow Blocks Containing Different Treatments of Rice (Oryza sativa) Husk

Concrete hollow blocks (CHB) have proven their significance in the modern construction of various human architecture. Rice husk is an organic waste product and a major by-product of the agricultural biomass and rice milling industry. In the Philippines, utilizing this agricultural waste may potentia...
