1) With using River sand :
• Cement one bag ……….. 50 Kg
• Sand 135 Kg
• Agg. 20 mm 135 Kg
• Agg. 12 mm 67.5 Kg
• Water 27.5 ltrs
Strength achieved after 7 days curing………..174.81 Kg/Cmsq.
2) With using Artificial sand : Proportions
are by weight
• Cement one bag 50 Kgs
• Sand (artificial m/c made) 125 Kgs
• Agg. 20 mm 137 Kgs
• Agg. 12 mm 75 Kgs
• Water 27.5 Ltrs
Strength achieved after 7 days curing …….186.67 Kg / Cmsq.
Similar test is performed with higher grade
Concrete Mix Design M 55
M 55 concrete is designed for River sand and
artificial sand.
Results are as follows:
1) With using River Sand : All proportions
are by weight
• Cement 50 Kg
• River Sand 75 Kg
• Agg. 20 mm 75 Kg
• Agg. 12 mm 37.5 Kg
• Water 19 Ltrs
Strength achieved after 7 days curing …….441
Kg per Sq.cm
2) With using Artificial Sand : All
proportion are by weight:
• Cement 50 Kg
• Artificial Sand 70 Kg
• Agg. 20 mm 80 Kg
• Agg. 12 mm 35 Kg
• Water 19 ltrs
Strength achieved after 7 days curing …….468.14 Kg per Sq.cm
Conclusion:
From the above design results it can be
observed that the strength of Concrete increases
with Artificial Sand. More over the presence
of Fines in artificial sand increases the
workability and gives more sound Concrete. The
slabs, using Artificial sand, are more leak
proof than by river sand. |
