This light weight aggregate is further classified as: i. Clinker Aggregate: It is called cinder in It is made from well burnt residue of industrial high temperature furnaces, fused into lumps. The clinker should be free from harmful varieties of unburnt coal, which is a main source of unsoundness in the concrete made from this aggregate. has laid down limits of loss on ...
nature of the slag, resulting in a light weight aggregate suitable for use in concrete. Quenching the molten slag into glass granules by using high pressure water jets produces granulated slag. Quenching prevents the crystallization of minerals constituting the slag composition, thus resulting in a granular, glassy aggregate. This slag is ...
slag lightweight aggregate concrete has also achieved certain research progress and engineering practice in China [1], Jilin Province volcanic slag reserves rank first in the country, of which light volcanic slag accounts for 30 million m3. Experts and related scientific research institutions have carried out a series of experimental studies on volcanic slag concrete and hollow blocks. Such as ...
processed through a screening and crushing plant and is processed into many sizes for use primarily as a construction aggregate. Common uses are as aggregates in readymix concrete, precast concrete, hot mix asphalt aggregate, septic drain fields and pipe backfill. EXPANDED SLAG • Pelletized or Expanded Slag is quickly cooled using water or steam to produce a lightweight aggregate that can ...
ed slag is such type of light weight aggregate which is a byproduct of quenching blast furnace slag as produce by the manufacturing of pig iron. The slag should have the following requirement: The heavy impurities should be removed from it. Volatile impurities such as coke or coal should not be contaminated in it. Sulphate should be removed from it. ed slag is manufactured by iron ...
Most lightweight aggregate is produced from materials such as clay, shale, or slate. Blast furnace slag, natural pumice, vermiculite, and perlite can be used as substitutes. To produce lightweight aggregate, the raw material (excluding pumice) is expanded to about twice the original volume of the raw material. The expanded material has properties similar to natural aggregate, but is less dense ...
A particle size was discovered that, with limited crushing, produced an aggregate grading suitable for making lightweight concrete (ESCSI 1971). Commercial production of expanded slag began in 1928, and in 1948 the first structuralquality, sinteredshale, lightweight aggregate was produced using shale in eastern Pennsylvania.
Mechanical strength properties of various flyash aggregate were tested for crushing strength and impact strength. The investigation results suggested that the coldbonded flyash lightweight aggregate using slag showed a highest crushing strength of MPa and also exhibited lower water absorption of %. The influence of binary blends of flyash and a binder was observed to be an ...
furnace slag, natural pumice, vermiculite, and perlite can be used as substitutes, however. To produce lightweight aggregate, the raw material (excluding pumice) is expanded to about twice the original volume of the raw material. The expanded material has properties similar to natural aggregate, but is less dense and therefore yields a lighter concrete product. The production of lightweight ...
Byproduct lightweight aggregat es which are prepared by crushing and sizing ed and granul ated slag, cinders, and coke breeze. The first three types of lightweight aggregates are produced from naturally occurring materials while the fourth is produced as a byproduct of i ron and steel product ion. Lightweight aggregates are distinguished from other mineral aggregate materials by their ...
Cold bonded lightweight aggregate (LWA) was produced by adding 0%, 25% and 50% granulated blast furnace slag (GGBS) or rice husk ash (RHA) to fly ash (FA) by the pelletization process with cement additives. The results show that GGBS addition significantly improved the crushing strength of LWA, whereas there was no effective on crushing strength of LWA when RHA was used.

lightweight aggregates can be produced from industrial byproducts such as fly ash, bottom ash, silica fume, blast furnace slag, rice husk, slag or sludge waste or palm oil shell, shale, slate, clay. The use of cost effective construction materials has accelerated in recent times due to the increase in the demand of light weight concrete for mass appliions. The present experimental ...
Expanded shale is artificial light aggregate for structural use after shale is artificially heated and expanded. Blast furnace slag is a byproduct of the steelmaking process and is usually mixed with cement to make concrete. Fly ash is the fine residue from the combustion of coal and can be used to make concrete or cement. Recycled Aggregates / Secondary Aggregates （Construction waste ...
