a mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. such comminution is an important unit operation in many processes. there are many different types of mills and many types of materials processed in them. historically mills were powered by hand or by animals, working animal, wind or water. in modern era, they are usually powered by electricity. the grinding of
keywords: refractory, periclase–carbon, material recycling the recycling process of post mortem mgo–c (mc) materials is based on carbon removal from the crushed material. the laboratory results of the annealing of the crushed post–mortem mc bricks in a static layer, in an air atmosphere in an electric furnace are presented.

three types of recycled products were investigated: i) aggregate a, ii) aggregate b and iii) aggregate c (fig. 1). according to the manufacturer, aggregate c is composed ofequalvolumesofaggregatea,aggregatebandsandb. it is important to point out that aggregate c represents around 44 % of the products sold by the recycling plant nowadays. 2.1.2.
the crushed aggregate is divided into high-quality recycled aggregate of 5-20 mm by secondary screening, which can be used in the concrete manufacturing of c25-c30. the high-quality recycled fine aggregate of 0.15 mm-5 mm and the fine powder

when the a/c ratio was 4, the strength values were high, and as a result, the mechanical properties were poor. with respect to aggregate gradation, it was determined that a grain size distribution of 9.50–12.50 mm was most suitable for this pervious concrete. recycled aggregates with low strength produced low strength concrete.
coarse and ﬁne aggregates, which include crushed, manu-factured, recycled, or marine aggregates. their physical properties including shape, size, texture, and grading including micro-ﬁnes can vary signiﬁcantly from the refer-ence state of aggregates that originated in a river. even though they marginally satisfy the standard of aggregates, its
16,000 tons of solid wastes from civil construction are produced daily in são paulo. lab tests show similar behavior of rcdw aggregate and a standard granular material. proper compaction energy increases the breakage of rcdw aggregate and its resistance. permanent deformation is one of the main problems of the rcdw aggregate. rcdw aggregate may be utilized as coarse base and sub-base
this paper presents an experimental research on mechanical properties of recycled aggregate concrete (rac) at low and high water/binder (w/b) ratios. concrete at two w/b ratios (0.255 and 0.586) was broken into recycled concrete aggregates (rca). a type of thermal treatment was employed to remove mortar attached to rca.
results show that the incorporation of recycled aggregate decreased the compressive strength of concrete at ages of 7 and 28 days. the decline in the compressive strength was more significant when the replacement percentage exceeds 50%. mass losses of concrete specimens were found to be increased as the level of recycled aggregate increased.
crushed concrete aggregates also called as recycled concrete aggregates are fragments and pieces of concrete buildings which are demolished or rebuild. these crushed concrete are cleaned from dirt and broken to smaller pieces to manufacture aggregate which is termed as recycled aggregate.

aggregate industry aggregates are building materials used in construction, including sand, gravel, crushed stone, and recycled concrete. aggregates are mined and either used in their raw form (for example, as foundations) or serve as composite materials in the production of concrete and asphalt.
(2) for recycled aggregate concrete at a low water/binder ratio of 0.255 prepared in this research, flaws in gravel are the main factor responsible for the decrease in mechanical properties, while flaws in attached mortar are the main factor responsible for the decrease in mechanical properties of recycled aggregate concrete at a high water/binder ratio of 0.586.
different types of backfill materials are used in construction industry. backfill materials that are commonly used are described below with their engineering properties. 1. coarse-grained soils. coarse-grained soils include gravelly and sandy soils and range from clayey sands ( sc) through the well-graded gravels of gravel-sand mixtures ( gw) with
the manual soil compaction hammers are lifted to their maximum height and allowed to fall freely onto the soil specimen for the required number of blows. for standard proctors, the hammers weigh 5.5lb (2.5kg) and drop 12in (305mm). the modified proctor method uses a 10lb hammer with 18in (457mm) drop height for compaction.
internal curing (ic) is a method to provide the water to hydrate all the cement, accomplishing what the mixing water alone cannot do. in low w/c ratio mixes (under 0.43 and increasingly those below 0.40) absorptive lightweight aggregate, replacing some of the sand, provides water that is desorbed into the mortar fraction (paste) to be used as additional curing water.
