Question

3- %(30+0,1n) kum ve geri kalan çakıl karışımı, 1920 kg/m3 birim ağırlığa sahiptir. Kumun özgül ağırlığı 2.60 ve çakıl 2.70 ise, karışımdaki boşluk alanının hacimsel yüzdesini hesaplayınız.

3-% (30 + 0,1n) sand and the remaining gravel mixture has a unit weight of 1920 kg / m3. the sand
If the specific gravity is 2.60 and the gravel is 2.70,calculate the volumetric percentage of the void area in the mixture

Answer 1

Ima As its Mixture → 30% Sand, 70% Gravel. GS = 2.6 Gg - 2.7 Consider volume of mix be Im3 unit wt is 1920 kg mass of lm3 mix = 1920 kg. Ms= mass of sand in mix 0.3 x 1920 = 576 xg 0.7 x 1920 = mg = mass of gravel in mex - 0.221 m² Vs = Voi of sand in mix = 576 2.6x1000 density а = Vot of gravel in mix - 1344 0.4977 m 2-7x1000 13 44 kg mais As we know Vs + vg + vair - Vmixture. 0.221+ 0.4977 + Va= 1 m3 Va = 0.2813 m3 28.13 % % voida va x 100 ✓ - Ans.
