Engineers looking to stay compliant with local building codes should ensure they are using the version referenced by their jurisdiction's adopted IBC (International Building Code) or ACI 318 code cycle.

for sand-lightweight concrete) to safely reduce the calculated shear strength provided by the concrete ( Vccap V sub c Durability and Fire Resistance

): SLC generally has a lower modulus of elasticity than normalweight concrete of the same strength, affecting deflection calculations.

The primary benefit of following the ACI 213R-14 guidelines is the significant reduction in on a structure, which can lead to smaller foundation sizes and reduced reinforcement requirements. Key performance areas discussed in the guide 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 Engineers looking to stay compliant with local building

The document covers concrete with a balanced density (unit weight) generally between 90 and 135 lb/ft³ (1440 to 2160 kg/m³). It focuses on structural applications where the concrete must meet specific strength requirements while maintaining a reduced weight.

The guide categorizes aggregates based on their manufacturing process:

Fly ash or slag processed on a sintering grate. Key performance areas discussed in the guide include:

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
