摘要：

In this study, mix proportion parameters of expanded polystyrene (EPS) lightweight aggregate concrete are analyzed by using Taguchi's approach. The density, compressive strength and stress-strain behavior were tested. The optimal mixture of EPS lightweight aggregate concrete was selected among experiments under consideration to manufacture the lightweight hollow bricks. The results show that EPS dosage has the most significant effect on compressive strength of EPS lightweight aggregate concrete, then water and cement ratio, while the content of cement and sand ratio play a comparatively less important part. The relationship between density and compressive strength of EPS lightweight aggregate concrete is proposed as f(c) = 2.43 x gamma(2.997) x 10(-9). The legitimacy of the use of EPS lightweight bricks made by EPS lightweight aggregate concrete is confirmed. (C) 2011 Elsevier Ltd. All rights reserved.
