Abstract

Cellular Lightweight Concrete Brick (CLC) is a material alternative that always used in building construction. Snail Shells Powder (SCB) and Shell Shells Powder (SCK) are home industry waste material from Kediri and Sidoarjo. Chemical compound of both waste materials is dominantly calcium. Therefore, these chemical compounds can use to replace the cement composition. The objection of this research is to find out the affect of SCB dan SCK on Cellular Lightweight Concrete Brick into density and compression value. Fabrication of Cellular Lightweight Concrete Brick is conducted at PT. Banancon Sidoarjo and the fabrication of CLC brick use Foaming Agent as a bubble maker chemical then mixing into mortar concrete and waste materials. The result that using waste material SCB and SCK on CLC brick can affect the quality of CLC brick. CLC brick with SCB material can increased density of mortar CLC brick with value 1.2928 gr/cm 3 or percentage of enhancement is 1.44% from density value on 0% percentage of SCB. For density value on CLC brick with SCK does not to show significantly increased value. Compression value without drying by oven on SCB material shows increase value than CLC with SCK material, maximum value of increasing compression test is 4.616 MPa on 4% of SCB material. In addition, compression value with drying by oven is increasing constantly until 6% of SCB with 4.935 MPa. In other hand, compression value of CLC with SCK material show drastically
