egg shell as a fine aggregate in concrete for sustainable,coarse aggregate: coarse aggregate: aggregates predominately retained on a no. 4 (4.75-mm) sieve are classified as coarse aggregate. generally, the size of coarse aggregate ranges from 5 to 150 mm. for normal concrete used for structural members such as beams and columns, the maximum size of coarse aggregate is about 25 mm..special concretes [part,aggregates or by adding colour pigments (astm c 979) or both. • if surfaces are to be washed with acid, a delay of approximately two weeks after casting is necessary. • coloured aggregates may be natural rock such as quartz, marble, and granite, or they may be ceramic materials. • synthetic pigments generally give more uniform results..

.08' to 1.0' (fine to medium gravel). granular soils are known for their water-draining properties. characteristics sand and gravel obtain maximum density in either a fully dry or saturated state. testing curves are relatively flat so density can be obtained regardless of water content. the tables on the following pages give a basic indication
basalt or crushed limestone, aggregate sizes of 12 mm ('h in.) or 19 mm (:y. in.), and coarse aggregate contents with aggregate volume factors (aci 211.1-91) of0.75 and 0.67. water-to-cementitious material ratios range from 0.24 to 0.50. compressive strengths range from 25
granite is a coarse to medium-grained rock that forms from the cooling of magma deep within the earth (intrusive). it is made up mainly of varying amounts of the minerals: quartz, orthoclase, muscovite, biotite and hornblende. the name is from the latin granum, for “grains”. quartz feldspar biotite mica (*) (*) granite - intrusive pegmatite
the hardness of granite is 6-7 whereas its compressive strength is 175.00 n/mm 2. streak is the color of rock when it is crushed or powdered. the streak of granite is white whereas its fracture is not available. luster of granite is the interaction of light with the surface of granite.
granite rock is crushed with a uniform feed of 2 in-spheres. the screen analysis is given in the table below. the power required to crush this material is 500 kw; of this 20kw is needed to operate the empty mill. the feed rate is at 150 ton/hr. calculate the power required for the second operation using: a) rittinger’s law b) kick’s law
the two most important characteristics of aggregate are particle shape and gradation. depending on what area of the country you work in you may find that concrete mixes are primarily made from gravel with a naturally rounded particle shape or from a rock (like limestone or granite) that is mined and crushed, producing more angular particles.

sieve mesh sizes are based on dimensions of the mesh size opening, or on the number of openings per linear inch. the two major standards governing test sieves and appropriate sizes are astm e11 and iso 565/3310-1, both of which specify parameters for aperture dimensions, mesh size, and statistical variations. opening sizes and mesh diameters for test sieves are often duplicated between these
it’s manufactured by grinding portland cement clinker and puzzolana (generally fly ash 10-25percent by mass of ppc) or by intimately and gradually mixing portland cement and fine puzzolana. puzzolana (burnt clay, shale, or fly ash) doesn’t have cementing value itself but gets the property of combining with lime to make a stable lime-puzzolana compound that has definite cementitious properties.

experimental plan in this work, 5%, 10%, 15% ,20% and30% of fine aggregate is replaced by glass powder for m20 grade concrete. cube specimens of size 150 mm x 150 mm x 150 mm were casted for different proportions with glass powder and compared with the properties of concrete prepared without glass powder (control mix). compression test was performed on the concrete after 7,14 and
granite slurry waste and iron waste are used as a fine aggregate by replacing which will fills the concrete gaps thereby increasing the strength characteristics of the concrete.
2.5. granite powder granite belongs to igneous rock family. the density of the granite is between 2.65 to 2.75 g/cm 3 and compressive strength will be greater than 200mpa. granite powder obtained from the polishing units and the properties were found. since the granite powder was fine, hydrometer

generally to displace a set weight (normally 100 g) of fine powder, and allows one to read off sg which is inscribed in a corresponding range onto the elongated neck (sans 5902). xylene is used because it has low surface tension with most powders, and for this has good penetration of fine open porosity.

this table is a data information resource for the specific gravity of many common general materials. while the data is extremely useful for design, actual individual samples will probably differ. temperature and purity will often have a definite effect. as 1000kg of pure water @ 4°c = 1 cubic meter, those materials under 1000kg per cubic meter
