STANDARDS FOR СЕМENT CONSUMPTION FOR DIFFERENT ITEMS OF WORK

Government of Gujarat

Roads & Building Department,

Circular No. PRC/10/2017/Cement Consumption/16/C

14, Sardar Bhavan, 2nd Floor,

Sachivalaya, Gandhinagar

Read :- Government of Gujarat, Road & Building Department, Sachivalaya, Gandhinagar

Circular No. SOR/1085/7/H(1) dated 08/12/1986

The uniform rate of cement consumption for various item was prepared and circulated

vide No. SOR/1085/7/H(1) dated 08/12/1986.

At the outset, current practice of estimating cement consumption in concrete item of

various Building, Bridge and Road project is based on above circular. However, it is generally

observed that the cement consumption derived by actual mix design is lower than the standard

cement consumption. Some of provision of the said circular become obsolete due to subsequent

revisions in the relevant IS code and IRC code. The maximum cement consumption as per IS 456-

2000 and IRC : 112-2011 is 450 Kg./m³. Also cement industry and aggregate crushing industry

have involved better quality of cement and aggregate over the years which have far reacting

impact on mix design of the present day concrete.

Mix design report of GERI reflecting entire Gujarat region have been considered in

averaging the cement consumption in various grade of design mix concrete. To minimize the

difference between standard cement consumption of cement and actual consumption derived by

mix design by GERI and the cement consumption as per provision of IS and IRC code falling

cement consumption is proposed for estimation purpose.

Looking the above facts, the cement consumption mentioned in circular vide No.

SOR/1085/7/H(1) dated 08/12/1986 is required to modify as per below:
