Hello friends please tell me some material name by use of which we can increase the performance of concrete except admixture like silica fume, or some other chemical admixture.

Please if someone have any idea then please inbox me. Please help me try to give some innovative ideas.

M30 to above grade is ratio 1:1:1 (Cement:Sand:Aggregates).

What is grade?
NAGESWAR said:   10 years ago
Grade means types of aggregate whether it is fine or coarse. According to the grade the aggregate shape is depend.

For: M5-1:5:10 M10-1:4:8 M15-1:3:6 M20-1:2:4 M25-1:1. 5:3 M30-1:1:1.

Grade means characteristics strength of concrete after 28 days.

For example M-10
M represent mix &10 is the compressive strength of concrete after 28 days.
Characteristics strength means the expected result of the cube should not below 5%.
