Abstract

This study bases on showing the pictures of how to keep a recycled fine aggregate well (quality control) and how to invent the measurement of mortar's quantities which largely effect on basic properties of matter: strength, durability and so on. As a result of the experiment by immersion, quantities of adhesive cement takes 7 to 8 days to stabilize by sulfuric. However, by hydrochloric acid, it takes a little quicker due to the first quick reaction, aggregate of the measurement of adhesive mortar by immersion used acid liquids are likely applicable following a suitable inspection and complementarity.
