Abstract
Lightweight concrete interlocking H-brick is an innovation wall material which is barely using cement as an adhesive between bricks. The presence of lip elements on the lightweight concrete interlocking H-brick allows bricks to be paired permanently and automatically interlocked and symmetrical, making the brick has interlock ability. The H-brick is more resistance to the earthquake, produce a better facade, also rapid installation process. This research used the lightweight concrete interlocking H-brick prepared with food packaging styrofoam waste and fly ash as material addition. The aim of this article was to compare the economic value of material needs of the lightweight concrete interlocking H-brick wall with two others wall material that was currently widely used, namely red brick and square lightweight concrete. The calculation of economic value was applied to a 98 type of housing. The calculation of material requirements and economic value in accordance with the Basic Unit Price and Unit Price of Principal Activity Building Construction Work and Residential of Surakarta City for the year 2018. The analysis results obtained the economic value of red brick, square lightweight concrete, and lightweight concrete interlocking H-brick was Rp. 36.649.718,82, Rp. 36.174.326,95, and Rp. 34.705.783,93, respectively. The results showed that lightweight concrete interlocking H-brick prepared with waste materials used in this research gain the cheapest material among the other two materials.
