Abstract


Epscrete, which is made by employing aggregate made of expanded polystyrene beads, is often used to make wall panels, block components, and insulating plates. For these products to have greater mechanical qualities, 400, 600, and 800 dose epscrete specimens were made in this research, which also considered the influence of cement quantity. The water-cement ratio was considered to be 0.5. In addition to the reference specimens, the same manufacture was carried out utilizing a 1% plasticizer admixture. Specimens were subjected to unit weight, ultrasonic pulse, water absorption, bending, and comprehension tests 7 and 28 days after production. The effects of the dose and plasticizer rate on the physical and mechanical properties of early and ultimate epscrete specimens were determined according to the unit weight, ultrasonic pulse velocity, water absorption rates, bending and compressive strength values. Increasing the dosage increased the ultrasonic pulse velocity, reduced water absorption by reducing the amount of gap and reduced water absorption, and increased compressive strength by approximately 65 % and bending strength by about 60 %. It has been determined that the mechanical and physical properties of epscrete are affected by dose and mixture ratios. By increasing the dosage, it has been seen that carrier light carrier blocks can be obtained.
