The measured slump values of quarry dust with constant water/cement ratio i.e. w/c ratio (0.55) are 37, 45, 50, 54, and 60mm for different mixes such as M 1 (0% quarry dust), M 2 (20% quarry dust), M3 (30% quarry dust), M 4 (40% quarry dust), M 5 (50% quarry dust) respectively. The variations of slump value with

12%The objective of this paper is to investigate the effect of quarry dust addition of different gradations on the compaction behavior of clay of different compressibility. A series of light compaction tests were carried out on soil mixes prepared with different quarry dust content with a locally available clayey soil and commercially available ...
IllangovanRet.al(2006)3 studied quarry dust as fine aggregate in concrete. Collins R.J et.al (1994)2 studied quarry dust in highway constructions. In the present investigations various percentages of sands such as 10%, 20%, etc., were added to crusher dust particles and the mixes were prepared and tested for compaction and
Quarry Dust. Fig.3 Variation Of Platic Limit with Increase in %of Quarry Dust. Effect of Quarry Dust on Compaction Characteristics The Maximum Dry Density of Expansive soil was found to increase from 15.80kN/m 3 to 17.75 kN/m and subsequently Optimum moisture content decreases from 28.5% to 25.2% up to the addition of 10% of stone dust

Soosan et al. ( 2005) have studied the effect of dif ferent percentages of quarry dust on. compaction characteristics of three different soils and observed an increase in MDD. values and decrease ...
cement ratio (w/c) which gives the slump of 60mm was selected from graph. The various w/c for different proportions of sand and quarry dust was presented in Table 2. Table 2: Workability of concrete ( slump 60mm) Fine aggregate Sand: Quarry dust water cement ratio ( w/c ) M20 M25 100:0 0.420 0.382 90:10 0.435 0.387 80:20 0.450 0.392
(CBR) and compaction parameters of black cotton soil are improved with the addition of quarry dust .It is observed that the CBR values are increased from 1.75% to 7.05%, the optimum moisture content has been reduced from 21.1% to 12.6% and maximum
cement with quarry dust mix volume is sufficient to get required strength (cement quarry dust ratio is 1: 10) and it can be used as a load bearing wall between columns. The system has identified main drawbacks while construction of a wall such as uneven compaction due to manual compaction, high operational and shutter lifting time etc.
2.2 Quarry Dust: Quarry Dust for this study was collected from Rajahmundry, East Godavari District of Andhra Pradesh, India. Quarry dust can be used in very large quantity, reducing the total cost of construction in addition to providing a solution to an environmental problem. The index and Engineering properties of the soil were
Greater than 25% replacement of quarry dust with sand this will be decreases the strength criteria. Abdul Razak.B.H, et al., [3] (NOV 2015) in their paper entitled "Impact of Quarry dust and Fly ash on the Fresh and Hardened Properties of Self Compacting Concrete",studied the importance of fly ash is used as a pozzolanic material as partial ...
SOIL COMPACTION HANDBOOK 5 Cohesive soils Cohesive soils have the smallest particles. Clay has a particle size range of .00004" to .002". Silt ranges from .0002" to .003".
Optimum utilization of quarry dust as partial replacement. compaction factor test, compressive strength (cube, cylindrical sample), split … surface, the ratio of the total surface area of all the particles to their volume. …. The measured slump values of quarry dust with constant water/cement ratio …. » More detailed.
Chapter 51.00 Мб. But for the quarry dust and other combinations of quarry dust and coarse aggregate as fillingFilling was done with proper compaction to achieve the required unit weight of 15 kN 1m3.3 • Each layer of the fill was compacted to get the same density by controlling the weight of soil and thickness of layer.
Smasher dust is blended in with high plastic rock to decrease the abundance disfigurement of the rock soils and increment the existence time of asphalt. Expansion of smasher dust diminished the plastic qualities and improved the CBR esteem. Orekanti Eshwara Reddy (2015); considered the impact of quarry dust on compaction properties of earth ...
Quarry dust obtained from Budera Quarry Mines near Raipur district and recycled aggregate is obtained from demolished old building in Raipur district. Here M20 mix of concrete of ratio 1:1.5:3 (Cement: Fine aggregate +Quarry dust: Coarse Aggregate +Recycled aggregate) and water cement ratio of 0.40 is used for preparing test samples
