The resulting product was lightweight (60% of the density of natural gravel) and satisfied the US EPA's toxicity characteristic leaching procedure (TCLP) test. The MIBA-based artificial aggregate was considered suitable for application as a coarse lightweight aggregate. 9.5.2 Islip, New York, USA: Artificial Aggregate From Rolite, Inc.
Artificial lightweight aggregate (LWA) is produced using water reservoir sediment, spent glass, and diatomaceous earth in various compositions and sintering temperatures between 1020°C and 1110°C. This study prepared aggregate samples whose physical properties included bloating index (BI), water absorption capacity (WAC), apparent density ...

The purpose of this study is to compare the bloating mechanism of artificial lightweight aggregate under sintering and rapid sintering conditions to identify the factors behind the bloating of the lightweight aggregate under these sintering conditions, and to find suitable temperature ramping conditions. The aggregate had an average particle size of 10 mm as formed using acid clay, and it was ...
The production of artificial lightweight coarse aggregate using fly ash has potential for its large-scale utilization in the construction industry and this is an area that merits attention in many ...
The present invention relates to a method for producing an artificial lightweight aggregate containing bottom ash. The method includes the steps of: (a) mixing 100 parts by weight of clay and 10-100 parts by weight of bottom ash to obtain a mixture; (b) extrusion-molding the mixture by using an extruder and cutting the extrusion-molded mixture to form a molded article; (c) drying the molded ...
• Artificial aggregates are made out of various waste materials. • Artificial aggregates are sometimes produced for special purposes: - for making lightweight concrete: burned clays, artificial cinders, ed slag, expanded shales and slate, sintered fly ash exfoliated vermiculite are used - for making heavy- weight concrete: steel rivet
for the manufacture of artificial lightweight aggregate and it has a promising future due to the increasing interest and its need for using as a recycling waste product. Pelletization is a worldwide process used for the manufacturing of artificial aggregates. According to the mechanism of agglomeration

In the last decade, there have been many innovations developed to replace the aggregate as material for concrete, particularly the coarse aggregate using the artificial lightweight aggregates a.k.a. ALWA. In the study, the main ingredient used to develop the artificial lightweight aggregates is the styro.
A wide variety of artificial lightweight aggregate options are available to you, such as graphic design, others. You can also choose from new artificial lightweight aggregate, as well as from tile, thin slab, and block artificial lightweight aggregate, and whether artificial lightweight aggregate is …
Pelletization is one method that predicts the production of balls from a powdery substance with extra stable round pellets [1]. Lightweight concrete manufactured from artificial aggregates or ...

LECA (Lightweight Expanded Clay Aggregate) Lightweight expanded clay aggregate (LECA) or expanded clay (exclay) is a lightweight aggregate made by heating clay to around 1,200 °C (2,190 °F) in a rotary kiln. The yielding gases expand the clay by thousands of small bubbles forming during heating producing a honeycomb structure.
Based on the classification of lightweight concrete according to the level of compressive strength and aggregate type by Mindess and Young [4], lightweight aggregate concrete using artificial lightweight aggregate (ALWA) or lightweight coarse sintered fly ash and ed slag aggregates can produce compressive strength values of 17-41 MPa with a ...
The possibility of creating lighter structures such as beams, piles and floors, cast on site or prefabricated, is feasible by replacing the larger parts of the traditional "natural" aggregate (gravel or stones) with an "artificial" aggregate, made up of expanded clay aggregates or ECA or Lightweight Expanded Clay Aggregate (LECA).

To get lightweight concrete, it is necessary to replace fillers such as coarse and fine aggregates whose weight and density are lower than the aggregates used for normal concrete or according to the ACI classification [16]. In this study, the replacement of coarse aggregate was replaced by making artificial coarse aggregate from ironwood.
