7.2 Testing Testing of concrete should be done in accordance with the approved testing procedures.
This guide provides information on the selection, proportioning, and use of structural lightweight aggregate concrete. It is intended to guide architects and engineers who are designing structures that require reduced dead weight, improved fire resistance, or better thermal properties compared to normal-weight concrete. aci 213r-14 pdf
: Guidelines on how to achieve specific compressive strengths (often exceeding 2500 psi) while managing the unique absorption characteristics of lightweight aggregates. : Guidelines on how to achieve specific compressive
4.3 Admixtures The use of admixtures can affect the durability of concrete. Mixture Proportioning: Unlike traditional concrete
Analysis of how lightweight aggregate concrete behaves in service, particularly regarding long-term performance and resistance to environmental factors.
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.
