    <dct:description>&lt;p&gt;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.&lt;/p&gt;</dct:description>
