การศึกษาความเป็นไปได้ของคอนกรีตผสมอีพีเอสโฟมที่ใช้แล้วสำหรับการรับน้ำหนัก

Abstract

This research is the feasibility study of concrete mixed with used EPS foam for loading, comparing with typical concrete and assessment for cost of concrete mixed with used ESP foam. The testing of compressive strength compared with typical concrete and concrete which mixed with EPS foam in rate of 0.1%, 0.2%, 0.3%, and 0.4 % by weight of fine aggregates and the curing age of 7,14 and 28 days. The results have shown that increased EPS foam the lower the strength compare to typical concrete. The proper percentage of EPS foam is no more than 0.3 % by weight, average strength of 218 kg/cm² and average density of green concrete is 2%-6% lower than density of typical concrete.   The cost of concrete is around 1980 baths per cubic meter which is 3% lower than typical concrete.
