Partial Replacement of Cement by Waste Paper Pulp Ash and Its Effect on Concrete Properties

Table 21

Raw material saving in one ton of cement production.

Percentage of replacement	0%	5%	10%	15%
Total raw materials	1.46	1.39	1.31	1.24
Saving of raw materials (%)	0	4.79	10.27	15.07

Replacing 5%, 10%, and 15% of cement by waste paper pulp ash will reduce 4.79%, 10.27%, and 15.07% of raw materials, respectively.
