EN 206-1 defines LWAC as concrete with oven dry density between 800 and 2000 kg/m3. The norm define classes for density D 1,0 – D 2,0 and compressive strength LC 8/10 - 80/88. The classes for LWAC compressive strength are different from nor-mal density concrete (NDC).
This book is written to give an overall picture of LWAC, from the historical background, aggregate production, proportioning and production of concrete, to applications in structures. Physical properties and chemical durability are described in detail. The physical properties include density, strength, shrinkage, and elasticity.

The pore mechanism of -based geopolymer is found to be different from that of lightweight aggregate-based geopolymer. This variation results in different physico-mechanical and durability properties such as better insulation properties (and lower thermal conductivity) for -based versus better mechanical properties for lightweight ...
Using structural lightweight concrete should pose few problems for knowledgeable contractors. With a typical unit weight of 90 to 120 pounds per cubic foot (pcf) and a compressive strength from 2500 psi to more than 8000 psi, structural lightweight concrete is a versatile building material. Since it is generally 20% to 40% …

The strength of lightweight self-compacting concrete generally depends on the concrete mix design, type of lightweight aggregate, and its characteristics. Other factors like water/binder ratio, inclusion of pozzolan, fiber, and nanomaterials have almost similar behaviors that can be observed in conventional concrete.

Since 1990s in Vietnam, Lightweight Aggregates have been produced by rotary kiln from expended clay or slate, which is called "Keramsite" (K) [1]. Since then, Lightweight Aggregate Concrete in general and Self-Compacting Lightweight Aggregate Concrete in particular has been studied and applied. However, it is difficult to produce …
Arcosa Lightweight Rotary Kiln11728 Highway 93Boulder, CO 80303303.499.1010 Arcosa Lightweight is the largest producer of rotary kiln expanded shale and clay lightweight aggregate in North America, with production facilities in California, Colorado, Texas, Louisiana, Alabama and Arkansas.

Based on the reviewed literature, concrete containing coconut shell as coarse aggregate with normal sand as fine showed the 28-day compressive strength between 2 and 36 MPa with the dried density ...
Lightweight concrete has long been used for suspended floors in order to reduce the weight on the structure and to increase the fire rating. And since a lightweight floor is typically thinner (5.25 inches versus 6.5 inches with normal weight for the equivalent fire rating), a lightweight floor will be 40% to 45% lighter than a normal-weight floor.
Lightweight concrete (LWC) is a broad term that mainly consists of aerated concrete, no-fines concrete and lightweight aggregate concrete (LWAC). LWC can be produced by inducing aeration or omitting fine content or by using lightweight aggregates. Lightweight aggregates are mainly obtained in two ways.
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.
The ultrasonic pulse velocity test was conducted according to ASTM-597. The tests for hardened concrete were carried out at the age of 3, 7, 14, 28 and 56 days. 3. Results and discussion 3.1. Test results of lightweight aggregate 3.1.1. Strength of lightweight aggregate Failure point loading and crushing strength of LWA are given in Table 4.
These vary from lightweight aggregate concrete, ed concrete, or Autoclaved Aerated Concrete (AAC). The aggregates used in AAC are extremely fine, even smaller than a grain of sand. This …
The production of concrete requires aggregate as an inert filler to provide bulk volume as well as stiffness to concrete. Crushed aggregates are commonly used in concrete which can be depleting the natural resources and necessitates an alternative building material. This led to the widespread research on using a viable waste material as aggregates. Fly ash …

The representative light weight aggregate with a dry specific gravity of l.38 will de velop a 54 percent fraction of enclosed aggregate particle ceramic solids and a remaining 46 percent pore volume (Figure 2). This leads to the illustration of the overall porosity in a bulk loose lightweight aggregate sample as shown in Figure 3.
Lightweight aggregate concrete is undergoing something of a renaissance. Although this material has been available for many years, only now is it being used more widely. This book provides a comprehensive review of this growing field from an international perspective.
