Codes and Standards for lightweight aggregates include ACI 213R-03: Guide for Structural Lightweight-Aggregate Concrete, and ASTM C330 / C330M – 09 Standard Specification for Lightweight Aggregates for Structural Concrete. The use of lightweight aggregates can be very beneficial and cost effective. However, when producing concrete using lightweight aggregates, there are several things you should be aware of. Fluctuations in the gradation, specific gravity, absorption, and moisture content ...
conventional (normal weight)aggregate. When used to make concrete, lightweight aggregate is simply a lighter type of rock, so the same admixtures are used,and batching, placing and finishing can be accomplished using the same equipment. Lightweight concrete has been successfully pumped long
Big River Industries, Inc. produces an expanded clay lightweight aggregate at its Erwinville, Louisiana plant. The aggregate is sold under the trade name "GRAVELITE". GRAVELITE expanded clay lightweight aggregate is structural grade aggregate for use in ready-mixed concrete products, as well as asphalt paving and geotechnical engineering projects.
Also, ready mixed concrete plant is applicable for small and medium-sized manufacturing factory for precast concrete. Simply, ready mix concrete batching plant is used to mix ready-mix concrete. Ready-mix concrete consists of cement, aggregates, water, additive and mineral admixture, which are in a certain proportion.
Brief History of ESCS and ESCSI. For over a century, ESCS has been used successfully in more than 50 different types of applications. The most notable among these are lightweight concrete masonry units, high-rise buildings, concrete bridge decks, high performance marine platforms, asphalt bituminous surface treatments, lightweight chip seal, soil conditioner and lightweight geotechnical fills.
One of the things that makes concrete so strong is the sand and gravel aggregate used in the mix. This rocky material naturally makes concrete heavy, limiting its transportation and use on some occasions. Making concrete lighter is possible, though, simply by replacing the aggregate with a lighter material such as pumice.
United States is or is becoming limited. In such areas, the use of recycled aggregate is beginning to serve as an environmentally friendly and economically viable solution. Many European countries have placed a tax on the use of virgin aggregates. This process is being used as an incentive to recycle aggregates.
blast-furnace slag is also used as fine or coarse aggregate. The aggregates are usually washed and graded at the pit or plant. Some variation in the type, quality, cleanli-ness, grading, moisture content, and other properties is expected. Close to half of the coarse aggregates used in portland cement concrete in North America are gravels;
requirements for aggregates for use in concrete. Aggregate produced from rock, gravel, metallurgical slag or suitable synthetic materials may be used provided the particular criteria set out for the aggregate is met. AS 2758.1 sets out the requirements for the quality of a material source and the properties of the coarse and fine aggregate.

Aggregates: The aggregates used in plain concrete are suitable for fiber reinforced concrete. The aggregates are normally divided in two categories, namely fine and coarse. Fine aggregate normally consists of natural, crushed, or manufactured sand. In some instances, manufactured lightweight particles are used for lightweight concrete or mortar.
The required properties of the lightweight concrete will have a bearing on the best type of lightweight aggregate to use. If little structural requirement, but high thermal insulation properties, are needed then a light, weak aggregate can be used. This will result in relatively low strength concrete.
