8.2 Maintenance Regular maintenance of concrete structures should be done to prevent damage and deterioration.

Structural lightweight concrete is defined by its density and minimum compressive strength. According to ACI specifications, structural LWAC must have: aci 213r-14 pdf

Clay, shale, or slate is heated to roughly 2000°F (1100°C), causing the material to expand or "bloat" into a porous structure. structural LWAC must have: Clay

Lightweight concrete yields a lower modulus of elasticity compared to normalweight concrete of equal compressive strength. The lower stiffness of the porous aggregates means structural members will experience greater deflections under identical loading conditions. Engineers must use modified empirical formulas provided in the text to calculate Eccap E sub c accurately. 2. Shear and Torsional Strength aci 213r-14 pdf
