state’s 30-year-old concrete highways by 10 to 15 years (www. cement. org/pavements). Grinding of PCC pavements is done to remove surface irregularities often caused by faulting, curling, and warping of the slabs and improve smoothness. Diamond grinding as a concrete pavement restoration technique dates back to 1965, when it was

Compressive strength and durability properties of

Compressive strength and durability properties of

grinding is related to the amount of material grounded. For 20% cement replacement represents 3.75 of the cost of Portland cement. This indicates saving of around 17% in the cost of Portland cement in concrete. The cost of cement represents almost 45% of the concrete cost. Therefore, over all cost of concrete will be reduced by more than 7.5%
