Natural river aggregate and crushed bricks aggregate were used. After demolition of masonry structure bricks were crushed and separated into fractions 0/4, 4/8 and 8/16 mm (see Figure 1). Fig. 1 Crushed brick -fractions 0/4 and 4/8mm Properties and chemical composition of recycled brick aggregate are given in the Tables 1 and 2.

Maximum aggregate size can be defined in two different ways: Maximum aggregate size. The smallest sieve through which 100 percent of the aggregate sample particles pass. Superpave mix design defines the maximum aggregate size as "one sieve larger than the nominal maximum size" (Roberts et al., 1996 [1]). Nominal maximum aggregate size .

(a) One major UV-260 nm absorbance peak between density fractions 11 and 14 from the sham-control sample was resolved in the density gradient (sham, arrow). This peak shifted to higher density fractions 16–21 at 4 h (4 h, arrow, dashed line) and fractions 27–33 at 24 h of reperfusion (24 h, arrow, solid line), respectively.

The SSD density of the recycled concrete aggregate ranges from 2150 to 2680 kg/m³. The density values of recycled coarse aggregate vary from 2280 to 2680 kg/m³, higher than that of fine aggregate.

d) Fine aggregate Those fractions from 4.75 mm to 150 micron are termed as fine aggregate. The river sand is be used in combination as fine aggregate conforming to the requirements of IS 383- 1970. The river sand is washed and screened, to eliminate deleterious materials and over size particles.

LIGHTWEIGHT AGGREGATE CONCRETE: EFFECT OF AGE AND CURING METHOD Rita Nemes1 УДК: 666.972.125 DOI:10.14415/zbornikGFS26.04 Summary: For normal weight concrete we have conversion factors, when testing not at the age of 28 days or the curing of specimens is not according to the standard.

first hour, LDA fraction-I (16mm–8mm) and fraction II (8 mm - 4 mm) water absorption are 9.09% and 9.01% respectively i.e. the LDA absorbs almost 70% of total water absorption in first hour. • Loss on Ignition of LDA fraction (16mm-8mm) is 3.55% which conforms to the ASTM C330 requirement of maximum loss on ignition of 5%.

For example: artificial aggregate(bulk density 1120-1300 kg/m^3) normal weight aggregate(sp. gr. 2.5-2.7) bulk density 1520-1680 kg/m^3 . heavy weight aggregate (sp. gr. 2.8-2.9) bulk density >2080 kg/m^3. REMEMBER: Bulk density may be expressed in g/cm^3 but this presents some inconveniences, and this is why it is generally .
