Abstract
The objective of this research was to study the cementitious properties of cement paste mixed with electronic-laminated powder (EP), electronic waste and non-degradable, as a cement material. Portland cement Type 1 was partially replaced by EP at a replacement rates of 10, 20, 30, 40 and 50 % by weight. The chemical and physical properties of EP were studied. Properties of fresh and hardened paste were tested. The results showed that EP had silicon dioxide (SiO2) as a main component of 35.95 % by mass. Water requirement and setting time of EP-cement paste increased as the replacement rate increased. However, the density and compressive strength decreased as the replacement rate increased. In addition, the effect of EP mixed can significantly reduce the dry density and the thermal conductivity property of cement pastes.
