Concrete, Sawdust, Compressive Strength

Better concrete quality is required as concrete technology advances both in terms of the type of concrete 

mixture used and the amount of additional ingredients added to the mixture to boost the strength of the 

concrete The waste product of the sawmill business is called sawdust Adding it to the concrete mixture 

when adding fine aggregate is one way to go about it This research attempts to ascertain the compressive 

strength of sawdust added concrete as well as the outcomes of contrasting regular concrete with sawdust 

additions to fine aggregate at percentages of 3 5 and 7 SNI 03 7656 2012 was the planning 

combination utilized in this investigation It included a plan for compressive strength of 16 MPa and 

concrete tests at 7 14 and 28 days of age According to the test results the percentages of 3 5 and 

7 had average compressive strength values of 18 50 MPa 10 36 MPa and 7 77 MPa at 28 days of age 

The intended value of 16 MPa for compressive strength is exceeded by typical concrete after 28 days 

reaching a value of 19 79 MPa Based on the study s findings it can be said that the concrete s 

compressive strength decreases with increasing proportion of cempaka sawdust used in place of fine
