1/2/1992 · Better pumps and a better understanding of lightweight aggregate properties have made it easier to pump lightweight structural concrete. Pumping this material efficiently, however, requires a team approach that involves the design engineer, general contractor, pumping contractor, concrete producer, aggregate supplier and testing lab.
Lightweight concrete is made using lightweight aggregates of expanded shale, clay and slag. These are used to produce structural lightweight concrete with a freshly mixed unit weight of 90 to 120 pounds per cubic foot. Normal weight concrete is typically 135 to
11/10/2018 · Structural Lightweight Concrete is made with processed aggregates such as expanded or sintered clays, shale, slates, fly ash, and slag or with naturally occurring light weight rocks like pumice and scoria. The low concrete density is achieved by using low-density aggregates and a specific concrete mix design, which helps it offer significantly
Ozinga Chicago was called on to supply lightweight concrete for the Lake Street project, a steel frame building with a lightweight concrete slab on metal deck floor system. Specifications called for a concrete compressive strength of 4,000 psi at 28 days and a maximum equilibrium density …
Lightweight concrete has an average density of about 105 pounds per cubic foot compared to regular concrete which has an average density of about 150 pounds per cubic foot. Hi, I am Mike Day, owner of Day's Concrete Floors, Inc. in Maine, where I've been working with concrete for 40 years now, and this website is where I can share with you all the knowledge and wisdom I've gained from

1/6/2021 · Structural low-density (lightweight) concrete is structural concrete made with low-density aggregate having an air-dried density of not more than 115490 lb/ft3 (1850 kg/m3) and a 28 day compressive strength of more than360,000 1b/ ft3 (17.2 MPa) [ACI 213R].
Structural Lightweight Concrete. Structural lightweight concrete solves weight and durability problems in buildings and exposed structures. Structural concrete mixes designed with Utelite Expanded Shale Aggregates have strengths comparable to normal weight concretes, yet are typically 25% to 35% lighter. Utelite Expanded Shale Aggregates offer
Structural loads requirements dictated the use of lightweight concrete with a maximum equilibrium density of 120 pounds per cubic foot (pcf). The specified compressive strength for the lightweight concrete was 5,500 psi @ 28 days, and 6,000 psi @ 56 days.
A 1,440 foot-long floating concrete breakwater was constructed in the state of Washington using lightweight aggregate produced at Boulder, Colorado. The $8 million breakwater project was designed for the Port of Bremerton Marina to attenuate wind driven waves and ferry wakes.
