characteristic of lightweight aggregate for housing and the effect of material regarding the durability. The compressive strength, water absorption and workability are significant for the structural lightweight aggregate concrete. One of the ways to reduce the weight of structure is the use of lightweight aggregate concrete (LWAC).
Aug 26, 2007· 2. Lightweight block have superior fire ratings, with the actual rating depending on the type of aggregate used. 3. Lightweight block has superior insulating properties. 4. Both lightweight and Normal weight block can be used for much higher strength engineered walls (f''m up to 4500 psi)based on the strength of the units and mortar.
Lightweight concrete block. The True Lite innovation has paved the way for a slag-based formula to create the ultimate lightweight unit. This product complies with Canada''s National Building Code as Type L2 concrete and is easily available in all modular sizes, shapes and profiles currently offered in the concrete block industry.
Lightweight Concrete. One of the most significant of the advantages of pumice aggregate concrete is its lightweight quality—up to one-third lighter than conventional sand-and-gravel concrete. This trait contributes to a decrease in structural steel costs and, consequently, job costs.
Advantages: Being chemically neutral, Leca aggregate and blocks, are the best bed for buiding installation and prevent pipe and wires from decay. Leca blocks are designed in a way not to be only lightweight but cover all required.
Geofill LD cellular (foam) concrete offers significant advantages in projects that require lightweight fill. Densities can be varied from 20 to 60 PCF and compressive strengths from 50 to 900 PSI. Load reduction (vertical and lateral) Stability and strength with only minimal weight.
The purpose of the present study is to recover marble waste and expanded perlite aggregate (EPA) for use as an additive to cementitious matrix building materials. The main goal is to produce a new insulation block floor from lightweight concrete (LC) by mixing sand from the waste marble crushing process (SWM), natural sand, and EPA. First, optimal mixture of natural sand, SWM, and EPA was ...
Aug 26, 2007· RE: lightweight vs. normal weight CMU. 24 Aug 07 13:41. ASTM C90 specifies that Normal weight block should have a density of over 125 pcf. and lightweight should be less than 105 pcf. Depending on you location lightweight will usually be between 90 and 100 pcf.
The environmental impact of lightweight aggregate concrete block, which use fly ash ceramic, was analyzed. The results show that AP and GWP are the most significant environmental impact categories accounting for 30% and 25% of the total environmental impact respectively. The results also show that, in different life cycle phases, the environmental load of the lightweight aggregate concrete ...

A structural light-weight concrete mix has a density of about 105 pounds per cubic foot compared to normal concrete with a density of 150 pounds per cubic foot. The light-weight concrete density is less because lightweight coarse aggregates and sometimes lightweight fine aggregates are used, which make the concrete weigh less.

1.1 This specification covers lightweight aggregates intended for use in structural concrete in which prime considerations are reducing the density while maintaining the compressive strength of the concrete. Procedures covered in this specification are not intended for job control of concrete.
Low-Density Natural Aggregate Concrete. Most low-density aggregates are volcanic in origin and include pumice, tuff, scoria, and cinders. Diatomite is also something used as the aggregate component of lightweight concretes. The advantage to these types of aggregate is that they often do not require processing apart from crushing or screening.
Structural lightweight aggregate concrete is an important and versatile material, which offers a range of technical, economic and environmental-enhancing and preserving advantages and is designed to become a dominant material in the new millennium. For structural application of lightweight concrete, the density is often more important than the strength.
