To help find the exact section you need in the standard, could you clarify if you are designing a (like a bridge deck or high-rise floor) or if you need help calculating the modulus of elasticity using the lightweight density reduction factor? Share public link

LWAC typically exhibits lower tensile strength than NWC. Because shear strength in concrete relies heavily on tensile capacity and aggregate interlock, a reduction factor (

When pre-wetted lightweight aggregates are integrated into a concrete mix, they act as internal water reservoirs. As the cement hydrates and desiccation occurs, the moisture is drawn out of the aggregate pores into the surrounding cement paste. This process reduces autogenous shrinkage, minimizes microcracking, and significantly extends the service life of high-performance concrete bridges and pavements.

Mixture Proportioning: Unlike traditional concrete, lightweight aggregates often absorb more water. ACI 213R-14 explains the nuances of "pre-wetting" or "pre-saturation" of aggregates to prevent them from sucking water out of the paste during mixing, which could lead to loss of workability and poor hydration.

If you are working on a specific design,g., bridge deck, high-rise floor, precast panel) The targeted and density

This chapter dives deep into the "ingredients." It details the internal structure of lightweight aggregates (such as expanded shale, clay, or slate) and their production methods. Understanding aggregate properties like particle shape, gradation, and absorption is critical because lightweight aggregates behave very differently from normal-weight aggregates during mixing.
