Limited Tenders are invited for Civil Works For Bkffpl At Kial Kannur : Earth filling supplying and filling earth obtained from approved quarries or equivalent quality free from all organic vegetation and foreign matter including all royalties, taxes, handling and transportation to site, stacking the same by the side of trench if required, spreading in layers not exceeding 150 mm, watering, compacting by mechanical means by power driven roller vibratory compactor of minimum 8-10 tonne capacity, testing at various stages to obtain 90%modified proctor maximum laboratory dry density
, removing the surplus material etc.
The unconfined compression test (UCT) was carried out based on the compacted sample with moisture content at 95% maximum dry density
The compaction behavior of recycled aggregates mixed with 5% to 25% sand, cement and brick was evaluated by Melbouci (2009), who made the following observations: (1) addition of 10% by mass of cement to RCA, leads to the maximum dry density
and a low optimum moisture content; (2) Addition to RCA of crushed brick particles having sizes lower than 0.
During the experiment the hydraulic conductivity (k), dry density

, and electrical conductivity--EC (measured in a suspension of 1:2 substrate:deionized water).
Previous resource estimates across this area used a dry density
s] can be a difficult parameter to estimate, since it depends not only on the volumetric water content, but also on mineral composition, porosity and dry density
(Peters-Lidard et al.
Physical properties such as available soil moisture, specific gravity, dry density
, and permeability, as well as chemical properties such as total N and total carbon contents, were measured in each plot before and after cultivation.
9% of water (OMC) is added and the soil is compacted in compaction test mould in 3layers with 25blows per layer, so as to get the maximum dry density
51 % nickel, using a 1% nickel cut-off and a dry density
Shape and Compact to 102% maximum dry density
