The performance of SLWC relies entirely on the quality of its porous aggregates. ACI 213R-14 categorizes these materials and details their production. Types of Lightweight Aggregates

The guide details the physical properties of Structural Lightweight Aggregates (LWA) and how they differ from normal weight aggregates. It explains the concept of equilibrium density, typically between 1120 and 1920 kg/m³ (70 and 120 lb/ft³). 2. Mixture Proportioning

Due to the lower modulus of elasticity, structural members made with LWAC will experience higher immediate deflections. Long-term creep and shrinkage can also be more pronounced. Engineers must carefully evaluate long-term serviceability requirements for long-span beams and thin floor slabs. 4. Proportioning, Mixing, and Placing aci 213r-14 pdf

1.3 Definitions For the purposes of this guide, the following definitions apply:

What specific are you designing? (e.g., high-rise floor slabs, bridge decks, precast panels) What is your target compressive strength and density ? The performance of SLWC relies entirely on the

By following these recommendations, professionals can ensure that they are using the most up-to-date and accurate information available for designing, constructing, and testing structural lightweight concrete.

Pumping introduces high pressure into the concrete line, which can force water deep into the pores of unsaturated lightweight aggregates. This causes the mix to stiffen instantly and clog the pump line. It explains the concept of equilibrium density, typically

The applications of ACI 213R-14 PDF are diverse, and the guide is useful for various construction projects, such as:
