This work investigated the effect of partial replacement of sand with quarry dust on the compressive strength flexural strength split tensile strength and water absorption of sandcrete blocks River sand was replaced with quarry dust at percentages ranging from 0 to 40 at cement/combined aggregate ratio of 1 6 The blocks were moulded using a Rosa Commetta
Quarry dust is a byproduct of the crushing process which Literature Review The suitability of quarry dust as a sand replacement material shows that the mechanical properties are improved and also elastic modulus was replaced with stone dust in percentage of 3 5 and 7 percent Similarly sand was replaced with stone dust in
Quarry dust Physical properties of the aggregate Table 2 shows the physical properties of the aggregate used in the moulding of blocks These values are also in line with those in the literature For example [10] and [1] obtained the values of 1296kg/m3 and 1230kg/m3 for quarry dust respectively
In the universe of landscaping and hardscaping one material often gets overlooked yet holds the key to many successful projects stone byproduct of crushing stones is more than what it appears to be Also known as quarry dust stone dust is a highly versatile substance prized for its multitude of serves as an important player in various

Quarry dust is obtained as soil solid wastes during crushing of stones to obtain aggregates This waste product is left in huge heaps in the neighborhood of the quarry causing serious health hazards
concrete and Quarry Stone dust concrete The strength achieved in concrete made with sand as fine aggregate achieved high strengths when compared with Quarry stone dust concrete However in both the cases strengths were falling at a super plasticizer dosage of % by weight of cement Similar behaviour was also observed in cubes of M40 grade
A Study on Influene of Quarry Dust on Behaviour of Self Compacting Concrete Kakarla Gopinadh Dr Kota Srinivasu Jujjuri Ushakranthi [] LITERATURE REVIEW 1 Celik et al 1996 observes crusher dust formed during the process of comminution of rock into crushed stone or crushed sand They investigated the effects of varying
The results show that a 20% substitution of pit sand with quarry dust produced the highest average compressive strength of N/mm 2 However the compressive strength of the blocks reduces as the proportion of quarry dust increases It is recommended that at most 30% of quarry dust replacements be used for non load bearing walls
