2.3 Construction Factors Construction factors can also affect the durability of concrete. Some of the most common construction factors that can affect concrete durability include:
Because lightweight aggregates are highly porous, they absorb water during batching. As the cement hydrates and consumes moisture, the aggregates slowly release this stored water internally. This minimizes autogenous shrinkage, reduces microcracking, and enhances long-term durability. 3. Superior Thermal Insulation aci 213r-14 pdf
According to ACI 213R-14, structural lightweight-aggregate concrete is defined by specific physical benchmarks: : A minimum 28-day cylinder strength of ) . Equilibrium Density : A range between ) . Equilibrium Density : A range between )
Designing with lightweight concrete requires modifications to standard structural code equations found in ACI 318. ACI 213R-14 explains the rationale behind these adjustments. Shear and Development Length Modification Factor ( According to ACI 213R-14
If you want to dive deeper into specific deployment details,
According to ACI 213R-14, structural lightweight concrete is defined by specific density and strength criteria:
