Pdf: Aci 213r-14

ACI 213R-14 is intended for a wide range of professionals involved in the design, construction, and testing of high-strength concrete, including:

The guide specifies the use of lightweight aggregates such as expanded shale, clay, or slate, which are often processed in rotary kilns to create a porous, low-density structure. Structural Advantages and Applications

ACI 213R-14 is a comprehensive guide developed by ACI Committee 213. It outlines the specific properties, production methods, and structural design considerations of concrete made with lightweight aggregates. Key Definitions

: The guide was updated to align with the provisions of ACI 318-14 (Building Code Requirements for Structural Concrete) . aci 213r-14 pdf

Lightweight aggregates possess lower thermal conductivity than natural stone aggregates. ACI 213R-14 highlights that SLC provides superior fire-resistance ratings, often allowing for thinner slabs or reduced concrete cover over reinforcing steel to meet local building code fire requirements. Internal Curing Benefits

Lower thermal conductivity means slower heat transfer. Consequently, floors and walls built with LWAC achieve higher fire ratings with thinner cross-sections. Batching, Mixing, and Field Handling

Explains that LWAC has a lower modulus of elasticity than normalweight concrete of equal strength, affecting deflection calculations. 3. Proportioning and Mixing

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.
