Structural light-weight concrete has been used for bridge decks, piers and beams, slabs and wall elements in concrete and steel buildings, parking structures, tilt-up walls, topping slabs and composite slabs on metal decking. For residential homes, light-weight concrete is used on top of the wood framed decking as a mass to hold the heat from ...
Oct 11, 2018· The structural light weight concrete with density 1600Kg/m3 and strength of 25 Mpa was highly beneficial here and also forms a weathering course. The same benefit of load reduction with no compromise in mechanical properties is ideal for the construction of steel deck slabs with Structural Light Weight Concrete.

lightweight concrete with an equilibrium density of 70 to 105 lb/ft³ (1120 to 1680 kg/m³) is infrequently used, most lightweight concrete has an equilibrium density of 105 to 120 lb/ft³ (1680 to 1920 kg/m³). Because lightweight concrete is often project-specific, contacting the aggregate supplier before project design is advised
Concrete is considered to be lightweight is the density is not more than 2200kg/m 3 (the density of normal weight concrete is assumed to be between 2300kg/m 3 and 2400kg/m 3) and a proportion of the aggregate should have a density of less than 2000kg/m 3. Lightweight concrete can be specified using the notation LC for the strength class, e.g ...
Cellular light weight concrete, also known as ed concrete, Crete, concrete or reduced density concrete, is defined as cement based slurry. It is a light weight, water resistant, fire- proof, sound proof and environment friendly. The main feature of this block is light in weight. Cellular Lightweight Concrete blocks are made of fly
Geo is a lightweight fill in compliance with ASTM D6817 that gives you control over your geotechnical project. Geo is engineered to give you the greatest possible control for your project application: from design and timelines, to materials and costs, …

Information not presented in this guide includes above-grade concrete walls, deep foundation systems (such as piles, drilled piers, or caissons), free-standing retaining walls (>4 ft [1.2 m]), post-tensioned slabs-on-ground, and elevated concrete slabs. Information on the use of lightweight concrete is not covered in this guide.
The main objective of this paper is to study feasibility of using ultra-lightweight (ULW) slab as an alternative design solution for floor component used in high-rise buildings.
Figure 12: Post-tensioned slab-column connection (WHE Report 68, Serbia and Montenegro) poured on the ground in forms, one on top of the other, as shown in Figure 11. Precast concrete floor slabs are lifted from the ground up to the final height by lifting cranes. The slab panels are lifted to the top of the column and then moved downwards to the
