Utilizing the Hydro Clean 1000 wash plant from Haver & Boecker Niagara gave Stalite the potential to increase productivity and expand into new markets Photo courtesy of Haver & Boecker Niagara As the world s only producer of expanded slate lightweight aggregate Stalite Lightweight Aggregate has never lacked a competitive edge But that
Buildex ® makes tomorrow better by making todays buildings roads and structures stronger and more Our Haydite ® lightweight aggregate is prepared by expanding select shale in a rotary kiln at temperatures that exceed 2 200°F The end result is a uniform and high quality lightweight ceramic aggregate that can be used in many applications
The purpose of this study is to manufacture lightweight aggregates for the recycling of water treatment sludge WTS to identify the physical properties of the aggregates and to present a means by which to utilize the manufactured lightweight aggregates The chemical composition and thermal properties were examined via a raw materials analysis The
Table 2 1 lists the States in which lightweight aggregate manufacturing plants are located Domestic production of lightweight aggregate in 1990 totaled 3 800 000 Megagrams Mg 4 200 000 tons and was valued at $26 million PROCESS DESCRIPTION1 The production of lightweight aggregate begins with mining or quarrying the raw material
Official manufacturer of Leca® lightweight expanded clay aggregate 10 20mm LWA Stability reduces the risk of embankment landslide and deformation; Reduced settlements to road structures rail beds pipelines and other structures; Reduced earth pressure in structural backfill against foundations retaining walls and bridge abutments; Limited compaction approximately
Lightweight Aggregate Concrete LWAC has been utilized over a long period of time The first known construction to use LWAC is more than 2000 years old using natural volcanic materials Among several structures to utilize LWAC at that time is the Coliseum in Rome the most well known Industrialized and commercial production of Lightweight
Laterlite Expanded Clay is a lightweight aggregate LWA with insulating characteristics made by expanding special natural clays at high temperature 1200°C Laterlite Expanded Clay is manufactured in different types and sizes in granular or crushed form standard lighter and insulating applications or structural high mechanical strength applications
The product is shipped by barge to three of Midwest s production facilities near St Louis Missouri ARCOSA s Jeff Speck says the lightweight aggregate is perfect for the units being produced for this large scale project Lightweight aggregate is manufactured specifically for production of concrete masonry units says Speck
5 Manufacturing of Lightweight Aggregates in Pilot Scale In the pilot plant of IAB Weimar gGmbH a jaw crusher The speed and inclination of the kiln are adjustable The kiln is fired with natural gas For the lightweight aggregate production the kiln operates at a firing temperature of 1200 °C The total residence time of the granules
5 Arcosa Lightweight Plays a Part for Vital Water Treatment Plant; Lightweight Aggregate Creates New Land for Cruise Ship Terminal; Arcosa Lightweight is the largest producer of rotary kiln expanded shale and clay lightweight aggregate in North America with production facilities in Alabama Arkansas California Colorado Louisiana Indiana
Lytag® lightweight aggregate is sold under a number of brands depending on the application Aggregates are selected and graded to provide the optimum performance for each use Lytag® lightweight aggregate Structural Lightweight Concrete Lytag® lightweight aggregate has been used in lightweight concretes since the early 1960 s
The utilization of industrial waste as a construction material is a big leap towards sustainable development Flyash is a waste material obtained from thermal power plants during combustion of pulverized research in relation to the use of sintered flyash aggregate to produce structural lightweight concrete is summarized in this paper
On the other hand the SP aggregate is a sintered pelletized fly ash aggregate that has been a successful commercial lightweight aggregate since the 1960s and can represent the general characteristics of lightweight pelletized fly ash aggregates and their performance in concrete Table 4 lists the properties of the three other main aggregates
In our manufacturing process kiln temperatures of 2100°F are carefully maintained and monitored Our lightweight aggregate is then cooled and sized to ASTM C330 and C331 and other customer specification Northeast Solite Corporation produces lightweight aggregates for sale as Solite
The representative light weight aggregate with a dry specific gravity of 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
Therefore there is a considerable opportunity to employ agricultural waste materials as substitutes for traditional components in the manufacturing of concrete Previous studies have demonstrated the successful utilization of plant based waste materials as lightweight aggregate in the production of structural grade LWAC [10] [11]
