<dc:description>Bottom ash is a byproduct from incinerated municipal solid waste (MSW) to produce electric
power and reduced the volume of the solid waste damped in open land fill that is serious
problem to the environment is used to produce bricks. Primary data was collected from Reppie
waste to energy plant using a sack by going to the plant and secondary data sources
from literatures review. The tastes that are take place during the research are include;
chemical contents of the municipal solid waste incinerated bottom ash (MSWIBA) analysis,
fineness of grinded bottom ash, Loss on ignition (LOI), consistency of blended mortar paste,
setting time blended mortar paste, workability of fresh blended mortar, Compressive
Strength of mortar and brick compressive strength and water absorption of cementitious
brick block for the percentage replacement of 10 %, 15 %, 20 % and 25 % of bottom ash
in weight. The chemical contents of sample are different than ordinary Portland cement because
of organic contents of the bottom ash and the physical characteristics of the sample are not fall
in the range of the ordinary Portland cement. The compressive strength of brick is attained clay
brick standards and categories of classes A except 20% bottom ash replacement. In the research
replacement of bottom ash is recommended in production of brick for construction and addition
of gypsum for workability, setting time and fast strength gain is also recommended for blended
mortar.</dc:description>
