Abstract

ABSTRACT This final project is aimed to know the strength of concrete brick pressure with materials lime sludge adding, that is considered by the strength of pressure, water absorption, and exterior concrete brick testing, also determination of the best composition of them. This final project can be categorized as experimental research with laboratory test technique, which is using dependent variable (variety testing), independent variable (mixed composition), and variable of control (the materials, how to make it, and the treatment). The research used three varians of mixed composition and a control composition, with the amount of samples are 5 matters of each other. The research was take a place in UNY Civil Engineering Laboratory. The step of research include : planning model and matters test composition that’s based on comparation (1Pc : 1Sludge : 7Ps;1Pc : 2Sludge : 6Ps;1Pc : 3Sludge : 5Ps and 1Pc : 8Ps as a control), preparation of materials and tools, making of matters examination, and data processing. Examination was accomplished if concrete brick had been 28 days. Analysis data technique is quantitative descriptive method and SNI 03-0349-1989 Generally, the examination gave data : a). Mean of the strength of pressure for own composition consecutively are 87.13 kg/cm², 74.83 kg/cm², and 61.53 kg/cm². It accomplished quality terms qualification are composition I quality level II, and composition II quality level II, and composition III quality level II ; b). The water absorption for each composition consecutively are 10,1%, 9.51%, and 9.29% which accomplished quality terms of qualification is composition III quality level B70 ; c). Deviation size of composition I has length’s 0,60 mm, wide’s 0,84 mm, and thick’s 0,82 mm ; composition II has 0,58 mm for length, 0,77 mm for wide, 0,81 for thick ; composition III has length’s 0,57 mm, wide’s 0,75 mm, and thick’s 0,88 mm ; which accomplished quality terms qualification ; d). Composition 1Pc : 1 Sludge : 7Ps is the best composition that’s based on SNI 03-0349-1989 with strength of pressure is quality II, water absorption quality’s B70, and deviation size length’s 0,60 mm, wide’s 0,84 mm, thick’s 0,82 mm. Keyword : Sludge, lime, concrete brick, strength of presure
