In this work, models for predicting six structural characteristics and cost of sand-quarry dust blocks were developed. Three model equations namely Scheffe's simplex lattice design (pseudo component), Scheffe's simplex lattice design (component proportion) and Osadebe's model were developed for .
Mar 01, 2012· AN INVESTIGATION ON EFFECT OF QUARRY DUST AS SAND REPLACEMENT ON COMPRESSIVE AND FLEXURAL STRENGTH OF CONCRETE ... The thermal conductivity of concrete of density 1000 kg/m3 is reported to be one-sixth the value of typical cement—sand mortar (Aidrige et al.,2001). A study by Giannakau and Jones (2002) exploring the
use of quarry dust (QD), which is a waste produced from the process of aggregates in quarry industry can be used as replacement of sand to helps overcome shortage of river sand [1], [2], and in construction industry for road base, or ... from 70 kg/m3 to 110 kg/m3, and thermal conductivity of around
The increase of thermal conductivity in the quarry dust specimens indicated a refinement of pore structures when incorporating a large volume of refined quarry dust. This could also be attributed to the smaller pores in control LFC specimen, which were more efficient to insulate thermal conduction.
partially replaced with quarry dust by weight of quarry dust in different percentages as 0%, 0.6%, 1.2%, and 1.8%. The water absorption, bulk density and thermal conductivity of each alternative material were compared. The results reveal that there is a considerable increase in the flexural strength, compressive strength, and reduction in ...
strength, density and coefficient of thermal conductivity of the fly ash aerated concrete in time. Siong Kang Limet.al. (2017), [10] investigates the feasible utilization of quarry ... quarry dust ratio were obtained separately for lightweight masonry block. It is to be noted that the optimum
Oct 01, 2017· Quarry dust was used to replace sand at ratios of 75% and , and four different water-to-cement ratios (w/c) of 0.52, 0.54, 0.56 and 0.58 were studied and compared. For a given w/c ratio, it was found that the use of high volume quarry dust could reduce the fluidity and increase the compressive strength and the thermal conductivity of LFC.
thermal conductivity reduction is due to the presence of 5.2% of porosity in the composite. The porosity reduces the conduction between the matrix and reinforcement materials. Also the quarry dust particle has lesser conductivity than the A356 alloy [7]. 4. Conclusions Castings of A356 alloy by adding different weight percentage of quarry dust
