The lightweight concrete masonry unit of the present invention contains, before being mixed with water, about 11 to 11.5% by weight of cement, about 47 to 47.5% by weight of pumice lightweight aggregate, about 22.5 to 23% by weight of other aggregate, about 18 to 18.5% by weight of ...
The Institute also defines normalweight as one word. ACI Committee 213 “Lightweight Aggregates and Lightweight Concrete” defines “lightweight concrete” as being concrete made with lightweight coarse aggregates and normalweight fine aggregates with possibly some lightweight fine aggregates. “All ...
Andrews, Ph.D.Program Objective: NineSigma, representing Owens Corning, invites proposals for materials or process modifications that will enable significant unit weight reductions in lightweight concrete.

The 𝜇𝛥μΔ value of the integral-unit specimens was 2.57, which was 11% lower than that of the divided-unit specimens. Overall, the ductility of the insulation panels governed by flexure was comparable to that of conventional lightweight concrete (LWAC) beams with the minimal ...
The ULCC generally has a unit weight of at least 40% less than that of conventional concrete and compressive strength of up to about 65 MPa with low permeability [23]. The ULCC has lower densities and higher specific strengths (compressive strength/density) compared with lightweight concrete (...
