2021-4-1 Artificial aggregates (AAs) are man-made construction material, and the properties greatly depend on its manufacturing process (e.g. granulation and hardening) and the raw materials (usually different source of wastes) used. This paper reviews the granulation process and suitable raw materials for each hardening method.
Utilization as a raw material for production of artificial sintered aggregate is one of the ways to make optimal use of even low-quality fly ash. Environmental and economic reasons lead currently to trying to upgrade the technology, which will fully use of the principle of self-sintering process based on content of combustible substances.The

2007-6-1 Dried aggregate pellets were fed directly through the raw material inlet at temperatures of 750, 850, and 950 °C and sintered at 1050, 1100, 1150, 1200, and 1250 °C for 5, 15, and 25 min into LWA.2.2.4. CoolingThe sintered LWA was rapidly quenched under sprayed water to below 240 °C and cooled under ambient air.2.3. Analyses
2007-7-19 The waste raw materials collected were oven dried at 105 °C until constant weight was obtained. After sifting through the size of 75 μm, the metal sludge and mining residues were evenly mixed at a weight ratio of 40%:60% into raw aggregate pellets of 3–5 mm diameter and then dried to contain 15% water .
Artificial aggregates (AAs) are man-made construction material, and the properties greatly depend on its manufacturing process (e.g. granulation and hardening) and the raw materials (usually
Combustion of coal creates a high amount of by-products in heat power plants. The largest share occupies fly ash as solid mineral residuals. Global pressure grows currently for the use of energy by-products. Utilization as a raw material for production of artificial sintered aggregate is one of the ways to make optimal use of even low-quality fly ash.
2019-5-31 Raw material should be processed through crushing, screening and washing steps and made into the aggregate which can meet the grading requirement finally. (1) Crushing. In order to break the mined materials into the

2019-4-17 The purpose of this study was to improve the recycling rate of industrial wastes by investigating the bloating mechanism of artificial lightweight aggregate depending on the ramping rate and time, which is a dynamic parameter in the production of artificial lightweight aggregate. In this study, coal bottom ash and dredged soil at a weight ratio of 1 : 1 from a
2021-12-9 ADVERTISEMENTS: In this article we will discuss about the natural and artificial types of light weight aggregates. 1. Natural Aggregate: They are not of uniform quality, and not found in many countries. As such they are not used universally for making light weight concrete. Out of all the natural light weight aggregate, only pumice is
2020-2-18 This study analyzed the characteristics of reject ash and bottom ash as raw materials for lightweight aggregate and suggested an optimum mixing ratio for recycling coal ash. The physical and chemical properties of reject ash and bottom ash for the manufacture of lightweight aggregate were examined. sintering tests were conducted to find an optimum mixing

The first step in making concrete is to prepare the cement. One type of cement, Pordand cement, is considered superior to natural cement because it is stronger, more durable, and of a more consistent quality. To make it, the raw materials are crushed and ground into a fine powder and mixed together.
They are made of various refractory raw materials through calcination, crushing processing or artificial synthesis, with a particle size greater than O. 088mm granular material. Aggregate is the main material in amorphous refractory materials, and generally accounts for 60% to 75% of the total composition.
