pemanfaatan serbuk gergaji untuk mengukur porositas pada pembuatan batu bata

Abstrak

A study entitled "the use of saw blades to measure porosity in brick making" where the initial stages were made of clay mixed with aiar and then a mixture of different sawdust, sawdust used were damar, kruweng, semarang and merbo. . Furthermore, after the mixture has been mixed, the bricks are formed and dried for several days until they dry and then enter the combustion stage, but after completing the combustion process, they enter the porosity measurement stage by immersing the bricks that have been burned for 210 minutes in order to see the incoming porosity levels. into the brick. The results obtained from measurements with the best value is 122% because this sample has good quality on the powder so that it is able to absorb water to the maximum, while the worst is 96% because this sample does not have a poor quality in absorbing water.
Keywords: brick quality, clay, sawdust and porosity of bricks.
