suppose if you take M25 grade concrete, 25 N/mm² is called characteristic strength of concrete, which means if you test 100 cubes of it, 95 cubes will give you strength greater than or equal to 25N/mm², but those 5 cubes may give …

Crushed concrete comes in all shapes and sizes. It packs well and also provides drainage. While its substance is concrete aggregate, in texture it will be closer to gravel. With crushed concrete, you will not need to worry about maintaining and repairing cracks like you would with concrete or asphalt surfaces.

They can be caused by a pour water to concrete mix when the concrete was poured. Or they can be caused by the speed at which the concrete cured. These cracks are pretty insignificant and typically are not damaging to the integrity of your concrete. Misaligned cracks are the big ones to look for, for the cause.

Crushed concrete is an environmentally favorable "green" building material since it requires less energy to generate than new concrete that is transported in between processing plants. You may feel good about contributing to the reduction of non-biodegradable garbage in our increasing landfills.

Unstabilized, loose crushed concrete has all the downsides that loose gravel does. It spreads and thins easily, requiring you to add more and to constantly even out your driveway so it doesn't develop bare spots and ruts. Crushed concrete also creates dust rather easily, which can stick to your vehicles and dirty them.
