Abstract: PURPOSE: A preparation method of lightweight concrete by using an ingot fused waste of expanded polystyrene is provided which improves compression strength. CONSTITUTION: A process for making lightweight concrete comprises: (a)a process for producing an ingot by fusing waste of expanded polystyrene with a frictional heat of 80-100°C through a miniature instrument of expanded polystyrene and extruding; b)a process for crushing the ingot in a plastic crusher mill of rotary-type; c)a process for adjusting grading of the crushed ingot where the biggest ingot is about 20 mm; d)a process for blending the ingot with cement powder, water, an additive, and silica hume for 6 min in a forced mixer. The weight of lightweight concrete by using the reclaimed aggregate of waste expanded polystyrene is reduced to 40-45%.

Abstract: PURPOSE: A concrete brick is provided to remarkably decrease the weight of a brick by manufacturing a brick using ingot which is made by melting the waste styrofoam, and to promote the thermal insulating effectiveness. CONSTITUTION: The concrete brick is manufactured by: mixing usual aggregate with the waste styrofoam reproduced aggregate which having its particle sized to be modulated according to the standard of aggregate about concrete bricks by pulverizing and processing the waster styrofoam ingot using a crusher; mixing cement to have 1:7 of ratio of the waste styrofoam to the reproduced aggregate; pressurizing using a vibrating press. Therefore, the concrete brick using the waste styrofoam reproduced aggregate meets the standard of KS F 4004, and particularly having 1120-2100 kg/m¬3 of unit volume weight, 93-320 kg/cm¬2 of compressing strength; 6.2-11.7 % of absorption rate, and 0.28-1.35 kcal/mh°C of heat conduction rate.
