Application of LECA Clay. Lightweight expanded clay has many advantages such as lightweight, low thermal conductivity (as low as 0.097W/mK), good sound insulation, impermeability, non-decomposition under harsh conditions, fire resistance, freeze-thaw resistance, and lightweight backfill.. LECA clay aggregate is an increasingly popular building material and is widely used …

The lightweight aggregate was placed in 12-inch lifts on top of geotech fabric and then compacted to the bottom of the pavement course. The use of a welded wire mesh and geo-tech fabric held the lifts of lightweight aggregate in place while constructing the new travel lanes. This allowed the …

Lightweight aggregate concrete manufactured by solid waste or recycled by-products is a burgeoning topic in construction and building materials. It has significant merits in mitigating the negative impact on the environment during the manufacturing of Portland cement and reduces the consumption of natural resources. In this review article, the agricultural and industrial …

Moreover, recycled lightweight concrete aggregates were also explored as lightweight aggregate replacement by Posi et al. (2016), and they observed that lightweight geopolymer concretes with densities between 1200 and 1500 kg/m 3 obtained 28-day compressive strengths of 4.5 and 17.5 MPa, respectively.

Lightweight aggregates (LWA) are characterized by lower bulk density in a comparison with common construction aggregates [1].LWA with a density below 2000 kg/m 3 are used particularly for the reduction of weight, improvement of durability, and enhancement of thermal and acoustic properties of concrete [2].Quite a few different lightweight materials have …

lightweight aggregate is placed in a 0.5 cf bucket in three layers, with each layer ... volume of lightweight aggregate in the abrasion machine to avoid overcrowding during the test. The results of the amended test method can vary depending on the aggregate, but for lightweight aggregate fill discussed in this ...

Lightweight concrete (LWC) is a kind of concrete that is made of lightweight aggregates or gas bubbles. These aggregates could be natural or artificial, and expanded polystyrene (EPS) lightweight ...

term most commonly used to refer to structural lightweight aggregate concrete. Structural lightweight aggregate concrete is defined by the American Concrete Institute's (ACI) Guide for Structural Lightweight-Aggregate Concrete (ACI 213R) as concrete made with structural lightweight aggregate as defined in ASTM C330, Standard Specification

However, the concretes presented significantly low-unit weight, approximately 1200 kg/m3. This work presented a structural lightweight concrete (ACI 213-R) using only lightweight aggregates and mostly plastic waste aggregate, with a compressive strength of up to 17.6 MPa, a unit weight of 1282 kg/m3, and an efficiency factor of 12.3 MPa·cm3/g.
