The main natural lightweight aggregates are diatomite, pumice, scoria, volcanic cinder, and tuff. Except for diatomite, all are volcanic in origin. Pumice and scoria are more widely used for hollow and solid concrete block production in Ethiopia. Normal weight aggregate is generally produced in Ethiopia by crushing parent rocks
Dec 18, 2015· Problematic excess fluoride groundwater drinking water sources exist in rural northeast China. La(III)–Al(III) soak leaching with heat treatment was used to modify lightweight aggregate scoria to purify high fluoride groundwater. The main elements in scoria were iron, sulfur, oxygen, silicon, aluminum, and calcium. The main mineral compositions were 29.44 % quartz, 30.04 % alkali feldspar ...
Our lightweight aggregates from Lytag® are made from fly ash generated by coal fired power stations. Our technology heats the fly ash to 1,100°C to create a hard pellet, with a honeycombed internal structure. Which can then be used as a superior, lightweight aggregate which is up to 50% lighter than natural aggregate.

basalt or crushed limestone, aggregate sizes of 12 mm ('h in.) or 19 mm (:Y. in.), and coarse aggregate contents with aggregate volume factors (ACI 211.1-91) of0.75 and 0.67. Water-to-cementitious material ratios range from 0.24 to 0.50. Compressive strengths range from 25 …
Jul 07, 2016· -- i.e., perlite is used as a light weight aggregate in such things as sound-absorbing tiles. The Aztec term iztli was so-to-speak surnamed teotetl, which has been translated as divine stone, apparently in reference to its many uses -- Aztecs fashioned both tools and items for adornment from obsidian.
This light weight aggregate is further classified as: i. Clinker Aggregate: It is called cinder in U.S.A. It is made from well burnt residue of industrial high temperature furnaces, fused into lumps. The clinker should be free from harmful varieties of un-burnt coal, which is a main source of unsoundness in the concrete made from this aggregate.

Construction aggregate, or simply aggregate, is a broad category of coarse- to medium-grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates.Aggregates are the most mined materials in the world. Aggregates are a component of composite materials such as concrete and asphalt; the aggregate serves as ...
Lightweight concrete may not be as structurally sound as traditional concrete, but it can be useful in some projects where weight is more important than strength. To make this concrete, combine 8 parts cement, sand and lightweight aggregate with 5 parts water.
Sundar et al. (2010) prepared a light-weight concrete by using hemalite light-weight aggregate and different other materials i.e. silica fume, fly ash, and GGBS (Ground granulated blast furnace slag). They include additional materials in the concrete to examine the compressive strength.
