Concrete mix containing 40% FA with 7% lime (replacing 47% OPC) and100% of FS (replacing 100% natural coarse aggregate) achieved the properties of normal concrete or even better properties at all ages. The results were confirmed by microscopic study such as Xray diffraction and petrography examination. Environmental compatibility of concrete containing FA and FS was verified by the .

Cement density: generally density of cement is around 1440kg/m3 or it is measured in other unit their density is in g/cm3, 94 in lb/ft3 and in kn/m3. The cement mixed with fine aggregate produces cement mortar for masonry, or with sand and gravel produces concrete. Ans. 1440 kg/m3 is density of cement.

Concrete Aggregates. Granular material either natural/processed from deposits of sand, gravel or rock. Normally sized as coarse aggregate or fine aggregate. Coarse Aggregate is normally greater than 5mm. Fine Aggregate is aggregate less than 5mm. Can be a single sized material typically 20mm, 14mm, 10mm,or 7mm or a graded aggregate consisting ...

 · Though recycled aggregates, fly ash and ferrochrome ash are waste materials used for making geopolymer concrete, experimental results revealed that up to 20% of replacement of recycled aggregate can achieve the strength and it can be the recommended percentage of RCA in concrete industry. Keywords Recycled aggregate Geopolymer Fly ash Ferrochrome dust Mechanical .

Masonry Densities. Aggregate blocks come in two types. Dense aggregate blocks have a density in the range 1800 – 2100 kg/m 3, while lightweight aggregate blocks (otherwise known as Medium Dense) have with a density in the range 650 – 1500 kg/m 3.. Aircrete blocks have a density in the range 400 – 900 kg/m 3.. Concrete bricks have a density in the range 1900 – 2100 kg/m 3 for Commons ...

For this purpose, concrete must have high strength and density. Heavyweight and high strength concrete can be used for shielding purposes. Such concrete with magnetite aggregates can have a density in the range of –4 t/m3, which is significantly higher than that with normal aggregates [5,6]. Concrete specimens prepared with mag

Relative density is used to calculate the volume occupied by the aggregate in various mixtures containing aggregate including hydraulic cement concrete, bituminous concrete, and other mixtures that are proportioned or analyzed on an absolute volume basis. Relative density (specific gravity) is also used in the computation of voids in aggregate in Test Method C29/C29M and in Test Method C1252.

concrete with a density (unit weight) of 2200 to 2400 kg/m. 3 (140 to 150 lb/ft. 3). Aggregates of expanded shale, clay, slate, and slag (Fig. 53) are used to produce structural lightweight concrete with a freshly mixed density ranging from about 1350 to 1850 kg/m . 3 (90 to 120 lb/ft. 3). Other lightweight materials such as pumice, scoria, perlite, vermiculite, and diatomite are used to ...

ferrochrome slag as replacement of coarse aggregate in concrete. They conducted the study on M50 grade of concrete. Their studies revealed that in concrete made with up to 75% replacement of natural aggregates with ferrochrome slag, the compressive and flexural strength was found comparable with that of the control sample.

Through the use of lightweight aggregates, normal weight aggregates, or blends of lightweight and normal weight aggregates, the resulting density of concrete masonry units can be varied by the producer to achieve one or more desired physical properties. ASTM C90, Standard Specifiion for Loadbearing Concrete Masonry Units (ref. 3) defines three density classes for concrete masonry .

 · Considering concrete density = 2400 kg/cum, One bag of cement and other ingredients can produce = 400/2400 = Cum of concrete (1:2:4) 01 bag cement yield = cum concrete with a proportion of 1:2:4. 01 cum of concrete will require.
