Lightweight bricks could be used as the substitute of conventional bricks for building wall materials. Lightweight brick has a weights beetween 600 to 1800 kg/m3. This research aims to investigate the characteristic of lighweight brick by performing compressive strength test, acoustic test, SEM and EDX test, and furnace teset. In this research, lightweight bricks were made by trial and errors made by adding combination of 0.3%, 0.6%, 0.9%, 1.2% and 1.5% of the weight of sand. After the foaming agent content was derived, trial and eror was performed to obtain the optimum 14 day compressive strength with 0,9% of variant. the CLC lightweight brick is the type of bricks which is constructed by adding air bubbles/foam agent to mortar mixture. It is necessary for the air bubbles to retain their shapes during the curing process of the mortar without triggering chemical reaction. An airlock was in a mixture of mortar structure of the cells that produce material, which contains the cavity the air with the size of the between 0,1 to 1,0 mm thick and spread uneven so that makes the nature of concrete better to prevent heat and more voice The curing process was performed by storing the samples indoor, in which the room temperatur varies over time. The sample size was 60x20x7.5 cm, made to investigate the impact of foaming agent to the compressive strength of the lightweight bricks (method of test SNI 03-6825-2002). The test results show the 7-day compressive strength was 0,489 MPa, the 14-day compressive strength was 0,578 MPa, and the 28-day compressive strength was0,667 MPa. The furnace test results show that the brick sample survives up to 500 ºC of temperature. The acoustic test results show that the bricks damp sound by 3%. The SEM and EDX test results indicate that the foaming agent forms air bubbles at the contact surface between the aggragate and cemen paste.
